Abstract
A construction of coupling spline sections of an automatic transmission includes: a rotary shaft section having an outer periphery formed with a spline section; a rotary hollow section having an inner periphery formed with a spline section which is coupled with the spline section of the rotary shaft section in a press fitting state; a support member; and a bearing disposed between a part of an outer periphery of the rotary hollow section and the support member. The bearing rotatably bears the rotary shaft section in such a manner as to transmit a torque between the rotary shaft section and the rotary hollow section. The spline section of the rotary shaft section and the spline section of the rotary hollow section which are disposed at least inside the bearing are coupled with each other in a loose state looser than the press fitting state.
