  • Patent number: 9746062
    Abstract: A lockup device (63) includes a lockup clutch (64) for establishing connection between a rotating body (44) of a torque converter (41) and a transmission shaft (55), a lockup control valve (70) that controls supply/discharge of pressurized oil from a hydraulic pump (69) to/from the lockup clutch (64), and a lockup oil passage (75) that introduces pressurized oil from the lockup control valve (70) to the lockup clutch (64). The lockup control valve (70) is arranged on an outer side face (18B) of an intermediate casing (18) in a position of radially overlapping the transmission shaft (55) in a radial direction of the transmission shaft (55). Further, a casing side oil passage (76) constituting the lockup oil passage (75) is formed as a linear oil passage that linearly extends in the radial direction of the transmission shaft (55) between the lockup control valve (70) and the transmission shaft side oil passage (77).
