a lid member which covers the upper portion of the case body; and a cover member which is attached to the lid member and which covers at least an opening part formed in the lid member, wherein: an intake port for taking in air from outside is formed in the cover member; a space part is formed between the cover member and the lid member; the opening part of the lid member is surrounded by a circumferential wall having a cylindrical shape; and a drain passage communicating with a drain port is connected with an outer circumference of the circumferential wall. ## Claims ### Claim 1 A case structure of a power equipment unit which contains power equipment mounted in a vehicle, the case structure comprising: a case body which contains the power equipment and an upper portion of which is open; a lid member which covers the upper portion of the case body; and a cover member which is attached to the lid member and which covers at least an opening part formed in the lid member, wherein: an intake port for taking in air from outside is formed in the cover member; a space part is formed between the cover member and the lid member; the opening part of the lid member is surrounded by a circumferential wall having a cylindrical shape; and a drain passage communicating with a drain port is connected with an outer circumference of the circumferential wall. ### Claim 2 (depends on 1) The case structure of the power equipment unit according to claim 1, wherein: a recess part having an annular shape is provided in the outer circumference; and the drain passage is connected with the recess part. ### Claim 3 (depends on 2) The case structure of the power equipment unit according to claim 2, wherein the recess part and the drain passage are formed by concaving the lid member. ### Claim 4 (depends on 1) The case structure of the power equipment unit according to claim 1, wherein: the intake port is provided on one surface of the vehicle in a front and rear direction; and the drain port is provided on an other surface of the vehicle in the front and rear direction. ### Claim 5 (depends on 1) The case structure of the power equipment unit according to claim 1, wherein the drain passage is tilted downward toward the drain port. ### Claim 6 (depends on 1) The case structure of the power equipment unit according to claim 1, wherein: in the cover member, a partition wall part is provided between the intake port and the opening part to extend downward from an upper wall; and a lower end of the partition wall part is positioned below an upper end of the opening part and below a lower end of the intake port. ### Claim 7 (depends on 1) The case structure of the power equipment unit according to claim 1, wherein the power equipment includes a vehicle driving battery. ### Claim 8 (depends on 1) The case structure of the power equipment unit according to claim 1, wherein the power equipment unit is arranged under a seat. ### Claim 9 (depends on 8) The case structure of the power equipment unit according to claim 8, wherein the intake port is arranged to be positioned under the seat even in a state where the seat moves to a most front side or a most rear side of the vehicle.
