A reserve tank structure includes a reserve hose for connecting a reserve tank to a radiator. The reserve tank includes a tank body portion for reserving a cooling water with a filling portion that extends upwardly from the tank body portion and includes a water supply port on an upper end thereof. A hose plug is connected to an end portion of the reserve hose. Mounting brackets support an intermediate portion of the reserve hose wherein the mounting bracket is mounted on the filling portion. ## Claims ### Claim 1 A reserve tank structure for connecting a reserve tank to a radiator by way of a reserve hose, comprising: a tank body portion for reserving a coolant; a filling portion extending upwardly from the tank body portion and including a coolant supply port on an upper end thereof; a hose plug to which an end portion of the reserve hose is connected; and a mounting bracket for supporting the reserve hose; wherein the mounting bracket is mounted on the filling portion. ### Claim 2 (depends on 1) The reserve tank structure according to claim 1, wherein a recessed portion is formed in an outer peripheral portion of the filling portion and the mounting bracket is mounted in the recessed portion. ### Claim 3 (depends on 1) The reserve tank structure according to claim 1, wherein a support portion for supporting the reserve tank on a vehicle body side is arranged in the vicinity of the mounting bracket which is mounted on the filling portion. ### Claim 4 (depends on 2) The reserve tank structure according to claim 2, wherein a support portion for supporting the reserve tank on a vehicle body side is arranged in the vicinity of the mounting bracket which is mounted on the filling portion. ### Claim 5 (depends on 3) The reserve tank structure according to claim 3, wherein the support portion is supported on a vehicle-body-side stay and a distal end portion of the support portion includes a tapered portion which is tapered toward a tip end thereof and a removal-preventing bulging portion. ### Claim 6 (depends on 4) The reserve tank structure according to claim 4, wherein the support portion is supported on a vehicle-body-side stay and a distal end portion of the support portion includes a tapered portion which is tapered toward a tip end thereof and a removal-preventing bulging portion. ### Claim 7 (depends on 1) The reserve tank structure according to claim 1, wherein the reserve tank is arranged below the radiator and an atmospheric pressure port in communication with an atmospheric side maintains a pressure in the inside of the reserve tank at an atmospheric pressure, said atmospheric pressure port being mounted on an upper surface of the tank body portion in an obliquely and upwardly projecting manner. ### Claim 8 (depends on 2) The reserve tank structure according to claim 2, wherein the reserve tank is arranged below the radiator and an atmospheric pressure port in communication with an atmospheric side maintains a pressure in the inside of the reserve tank at an atmospheric pressure, said atmospheric pressure port being mounted on an upper surface of the tank body portion in an obliquely and upwardly projecting manner. ### Claim 9 (depends on 3) The reserve tank structure according to claim 3, wherein the reserve tank is arranged below the radiator and an atmospheric pressure port in communication with an atmospheric side maintains a pressure in the inside of the reserve tank at an atmospheric pressure, said atmospheric pressure port being mounted on an upper surface of the tank body portion in an obliquely and upwardly projecting manner. ### Claim 10 (depends on 5) The reserve tank structure according to claim 5, wherein the reserve tank is arranged below the radiator and an atmospheric pressure port in communication with an atmospheric side maintains a pressure in the inside of the reserve tank at an atmospheric pressure, said atmospheric pressure port being mounted on an upper surface of the tank body portion in an obliquely and upwardly projecting manner. ### Claim 11 A reserve tank adapted to be connected to a radiator by a reserve hose, comprising: a tank body portion for holding a predetermined quality of fluid; a filling portion extending upwardly from the tank body portion and including a fluid supply port on an upper end thereof; a hose plug to which an end portion of the reserve hose is connected; and a mounting bracket for supporting the reserve hose, said mounting bracket being mounted on the filling portion for retaining the reserve hose relative thereto. ### Claim 12 (depends on 11) The reserve tank according to claim 11, wherein a recessed portion is formed in an outer peripheral portion of the filling portion and the mounting bracket is mounted in the recessed portion. ### Claim 13 (depends on 11) The reserve tank according to claim 11, wherein a support portion for supporting the reserve tank on a vehicle body side is arranged in the vicinity of the mounting bracket which is mounted on the filling portion. ### Claim 14 (depends on 12) The reserve tank according to claim 12, wherein a support portion for supporting the reserve tank on a vehicle body side is arranged in the vicinity of the mounting bracket which is mounted on the filling portion. ### Claim 15 (depends on 13) The reserve tank according to claim 13, wherein the support portion is supported on a vehicle-body-side stay and a distal end portion of the support portion includes a tapered portion which is tapered toward a tip end thereof and a removal-preventing bulging portion. ### Claim 16 (depends on 14) The reserve tank according to claim 14, wherein the support portion is supported on a vehicle-body-side stay and a distal end portion of the support portion includes a tapered portion which is tapered toward a tip end thereof and a removal-preventing bulging portion. ### Claim 17 (depends on 11) The reserve tank according to claim 11, wherein the reserve tank is arranged below the radiator and an atmospheric pressure port in communication with an atmospheric side maintains a pressure in the inside of the reserve tank at an atmospheric pressure, said atmospheric pressure port being mounted on an upper surface of the tank body portion in an obliquely and upwardly projecting manner. ### Claim 18 (depends on 12) The reserve tank according to claim 12, wherein the reserve tank is arranged below the radiator and an atmospheric pressure port in communication with an atmospheric side maintains a pressure in the inside of the reserve tank at an atmospheric pressure, said atmospheric pressure port being mounted on an upper surface of the tank body portion in an obliquely and upwardly projecting manner. ### Claim 19 (depends on 13) The reserve tank according to claim 13, wherein the reserve tank is arranged below the radiator and an atmospheric pressure port in communication with an atmospheric side maintains a pressure in the inside of the reserve tank at an atmospheric pressure, said atmospheric pressure port being mounted on an upper surface of the tank body portion in an obliquely and upwardly projecting manner. ### Claim 20 (depends on 15) The reserve tank according to claim 15, wherein the reserve tank is arranged below the radiator and an atmospheric pressure port in communication with an atmospheric side maintains a pressure in the inside of the reserve tank at an atmospheric pressure, said atmospheric pressure port being mounted on an upper surface of the tank body portion in an obliquely and upwardly projecting manner.
