A shift fork shaft formed by slidably fitting a plurality of shift forks according to the number of gears;
A plurality of actuators each lock each shift fork to the shift fork shaft according to a command, and when each actuator is turned off, each shift fork is engaged with the casing, and when a certain actuator is turned on, a specific shift fork is locked with the casing. a locking mechanism for disengaging and locking the actuator to the shift fork shaft; each actuator includes a first piston slidably inserted into a cylinder chamber;
an electromagnetic valve that drives a piston; a second piston that is slidably fitted on the outer circumferential side of the first piston; and a stopper that restricts the amount of movement of the second piston to be smaller than that of the first piston; 1. A shift mechanism for an automatic transmission, comprising: a spring member that biases a second piston along a locking direction of the first piston.
