Patent attributes
A motor including an intake-side conduit member disposed outside a casing that makes a connection between a cooling water intake section of a water pump and an intake hole, and a cooling water relay section provided outside the casing. The cooling water relay section communicates with a cooling water supply passage in the casing. A discharge-side conduit member that is disposed outside the casing connects the cooling water relay section to a cooling water discharge section of the water pump. Additionally, the other end of a transmission cooling conduit member that is branched from the cooling water relay section is connected to a water jacket of the transmission. The conduit members are preferably flexible hose members, for example. Accordingly, this unique construction improves a cooling water piping layout around a water pump, a discharge performance of the water pump, and an assembly workability of a motor.
