The partition wall 62 is used to partition the wiring space 59a and the lead-in space 59b. The outside of the frame 50 and the introduction part 92 is introduced from the outside of the swing frame 50 . The introduction portion 92 is inserted into the partition wall 62 via the sealing member 66 . According to this configuration, when the three-phase line 90 is introduced into the connection space 59a, the introduction part 92 of the three-phase line 90 can be extended from the introduction space 59b to the Wiring space 59a. Thereby, it is possible to prevent water from entering the connection portion of the motor connection portion 91 and the lead-in portion 92 .

PCU80具有設於外表面且沿前後方向延伸的冷卻翼片83。根據該構成，由於可使行駛風通過冷卻翼片83之間隙，因此可期求提高PCU80之空冷效果。The PCU 80 has cooling fins 83 provided on the outer surface and extending in the front-rear direction. According to this configuration, since the running wind can pass through the gaps of the cooling fins 83, it is expected that the air cooling effect of the PCU 80 can be enhanced.

PCU80之至少一部分係配置於電池6之下方。電池6係在長邊方向相對於上下方向朝前後方向傾斜的狀態下所配置。根據該構成，相較於在電池6之長邊方向沿上下方向的狀態下配置電池6的構成，可確保相對於伴隨連桿構件70之擺動所位移之PCU80的間隙。因此，其可設為適合於將PCU80固定於連桿構件70之構成的電池6之配置。At least a part of the PCU 80 is arranged below the battery 6 . The battery 6 is arranged in a state in which the longitudinal direction is inclined toward the front-back direction with respect to the up-down direction.
