Abstract: An axial piston pump has: a cylinder body that forms therein a cylinder chamber extending in an axial direction of a drive shaft and rotates integrally with a driven shaft; a piston that reciprocates in the axial direction of the drive shaft; and a cam device that rotates integrally with the drive shaft and has: a fixed cam member that has a cam surface capable of coming into contact with a cam follower coupled to the piston and is capable of rotating integrally with the drive shaft, with movement of the fixed cam member in the axial direction being restricted; and a movable cam member that has a cam surface capable of coming into contact with the cam follower and is capable of rotating integrally with the drive shaft, with movement of the movable cam member in the axial direction being allowed, irregularity differences in the axial direction of the cam surface of the fixed cam member and the movable cam member being different from each other.

Abstract: In a controller of a vehicle transmission, the transmission includes a continuously variable transmission 3 and a planetary gear mechanism 4 and is coupled to an output of an engine 1. The transmission includes a first shift mode using only the continuously variable transmission 3 and a second shift mode using in combination the continuously variable transmission 3 and the planetary gear mechanism 4. The controller determines the shift mode based on load of the engine 1 according to a required output and an input/output revolution speed ratio ? of the continuously variable transmission 3, and switches between the above two shift modes at the predetermined input/output revolution speed ratio.
