an oil pressure valve unit that controls transmission of the oil pressure generated by the master cylinder to the slave cylinder; a master-side connection pipe arrangement that connects the master cylinder to the oil pressure valve unit; and a slave-side connection pipe arrangement that connects the oil pressure valve unit to the slave cylinder, wherein the slave cylinder and the oil pressure valve unit are arranged on one side part in a vehicle width direction of the saddle-riding type vehicle, and the oil pressure actuator is arranged on another side part in the vehicle width direction of the saddle-riding type vehicle. ## Claims ### Claim 1 A saddle-riding type vehicle, comprising: a transmission that includes a clutch operated by an operation of a slave cylinder; an oil pressure actuator that includes a master cylinder which generates an oil pressure on an operation oil; an oil pressure valve unit that controls transmission of the oil pressure generated by the master cylinder to the slave cylinder; a master-side connection pipe arrangement that connects the master cylinder to the oil pressure valve unit; a slave-side connection pipe arrangement that connects the oil pressure valve unit to the slave cylinder; a left cowl member that covers a vehicle body left side part; and a right cowl member that covers a vehicle body right side part, wherein the slave cylinder and the oil pressure valve unit are arranged adjacent to one of the left cowl member and the right cowl member, and the oil pressure actuator is arranged adjacent to another one of the left cowl member and the right cowl member. ### Claim 2 (depends on 1) The saddle-riding type vehicle according to claim 1, wherein the clutch is arranged on the other side part in a vehicle width direction. ### Claim 3 (depends on 1) The saddle-riding type vehicle according to claim 1, wherein the oil pressure actuator and the oil pressure valve unit are arranged within a bank range of the saddle-riding type vehicle. ### Claim 4 (depends on 1) The saddle-riding type vehicle according to claim 1, further comprising: an engine arranged in front of the transmission, wherein the engine includes a cylinder that stands upward, and the oil pressure actuator and the oil pressure valve unit are arranged in front of and below the engine. ### Claim 5 (depends on 4) The saddle-riding type vehicle according to claim 4, further comprising: a discharge pipe that is connected to a front part of the cylinder, wherein at least part of the oil pressure actuator and the oil pressure valve unit is covered by the discharge pipe from a front direction. ### Claim 6 (depends on 4) The saddle-riding type vehicle according to claim 4, wherein the oil pressure actuator further comprises a motor for driving the master cylinder, wherein the master cylinder and the motor are arranged such that a longitudinal direction is directed in a vertical direction and are arranged to be inclined such that an upper end part is located at an outer position in a vehicle width direction, and a lower end part is located at an inner position in the vehicle width direction. ### Claim 7 (depends on 4) The saddle-riding type vehicle according to claim 4, wherein the oil pressure valve unit comprises an oil pressure sensor arranged such that a longitudinal direction is directed in a vertical direction and arranged to be inclined such that an upper end part is located at an outer position in a vehicle width direction, and a lower end part is located at an inner position in the vehicle width direction. ### Claim 8 (depends on 1) The saddle-riding type vehicle according to claim 1, further comprising: an engine arranged in front of the transmission, wherein at least a part of the engine is arranged between the oil pressure valve unit and the oil pressure actuator in a vehicle width direction. ### Claim 9 (depends on 1) The saddle-riding type vehicle according to claim 1, wherein an axis direction of the oil pressure valve unit intersects with a vehicle width direction, and an axis direction of the oil pressure actuator intersects with the vehicle width direction. ### Claim 10 (depends on 1) The saddle-riding type vehicle according to claim 1, wherein an axis direction of the oil pressure valve unit and an axis direction of the oil pressure actuator are arranged in non-parallel to each other.
