An automatic transmission comprises a transmission mechanism including plural planetary gear sets, a transmission case storing the transmission mechanism, and an end cover closing an opening at one end of the transmission case. A planetary gear set disposed the closest to the end cover is assembled in such a manner that before the end cover is attached to the transmission case, a sun gear is assembled to the transmission case and a pinion carrier is assembled to the end cover. A thrust washer is disposed between an end face of the sun gear and an end face of an inner peripheral portion of the pinion carrier. The thrust washer is a member for adjusting a gap which is formed in an axial direction in the transmission case, and the member is selected from plural ones which have different axial thicknesses from each other.

According to an operation of a shift lever to parking range, a cam member at a parking rod comes in between a parking pole and a support member, and the parking pole swings so that a pawl portion of the parking rod can engage with a parking gear. A concave holding portion to hold the support member is formed at a transmission case. The support member comprises a first cylindrical outer face having a first radius R1 which is supported in a concave inner face the concave holding portion to rotate in a specified range and a second cylindrical outer face (cam-contact portion) having a second radius R2 which contacts a cam member. The first radius R1 has a center which is located at the same position as that of the second radius R2. Herein, R2 is shorter than R1.
