A band brake actuator is for actuating a band brake on a planetary gearset. The band brake actuator comprises a actuator shaft; an output finger; and a linkage assembly. The linkage assembly connects the actuator shaft to the output finger such that rotation of the actuator shaft in a first rotation direction causes the output finger to engage the band brake on the planetary gearset, and such that rotation of the actuator shaft in an opposite, second rotation direction causes the output finger to disengage the band brake from the planetary gearset. Engagement of the band brake and the planetary gearset shifts the planetary gearset into one of a forward and a reverse gear and wherein disengagement of the band brake and the planetary gearset shifts the planetary gearset into a neutral gear.

A meshing engagement device includes a movable member; a first engaging element; a spring member; first engaging teeth formed on the first engaging element; and a second engaging element having second engaging teeth which engage with the first engaging teeth. Further, the meshing engagement device switches between an engagement state and a disengagement state, and the engagement state includes: a first engagement state where the spring member is brought into a state where the spring member is contracted in the axial direction; and a second engagement state where the spring member is brought into a state where the spring member is further contracted in the axial direction compared to the spring member in the first engagement state.

An automatic transmission which includes a first rotating member and a second rotating member is provided. The first rotating member includes an outer rotating member having a first outer power transmission part and an outer extending part, and an inner rotating member which is made of a different material from the outer rotating member and has a first inner power transmission part and an inner extending part. The outer and inner extending parts are coupled through a first extending part formed by axially joining them to each other at a caulking part. The second rotating member includes a second extending part having a recess indented on an opposite side of the first extending part. The caulking part has a protrusion protruding by being recessed from the first extending part to the second extending part. At least a part of the protrusion is located inside the recess.
