    • PROBLEM TO BE SOLVED: To form compact a hydraulic circuit apparatus having a plurality of solenoid valves.
      SOLUTION: The plurality of solenoid valves 14a and 14b are disposed on a pair of side faces 12a and 12b positioned parallel with each other and facing outwards so as not to be overlapped with each other in a direction perpendicular to the axes thereof, and assembled so that valve parts 24 can be overlapped with each other in the axial directions of the solenoid valves 14a and 14b. Also, because hydraulic switches 16a and 16b are disposed on the side faces 12a and 12b at positions corresponding to valve storage holes 18b and 18a in the side faces 12b and 12a on the opposite sides of the side faces 12a and 12b, a dead space in which the solenoid valves 14a and 14b cannot be assembled can be effectively utilized.

    • PROBLEM TO BE SOLVED: To provide a vehicular automatic transmission achieving sub assembly independently of a vehicle type, FF, FR, or whatever, thus actualizing a compact main line and suppressing the risk of stopping the main line. SOLUTION: A first planetary gear device 22 and a first friction engaging element 50 are supported in the direction of the axial center by an oil pump housing 42. Thus, the automatic transmission 16 using the oil pump housing 42 on which an oil pump 94 is assembled achieves the sub assembly. Namely, it achieves the sub assembly with a single type oil pump 94 independently of an automatic transmission different in size such as axial length, FF, FR, or whatever. The sub assembly allows the assembly of the oil pump 94, the first planetary gear device 22 and the first friction engaging element 50 on the oil pump housing 42 in a sub line, actualizes the compact main line, and suppresses the risk of stopping the main line.
