たことを特徴とする変速装置。 A gear type transmission; and an actuator unit configured to include a fluid pressure cylinder and a solenoid valve and to selectively open and close the solenoid valve to perform a gear change operation in a shift direction of the transmission by the action of fluid. , a transmission comprising means for outputting a command signal indicating a desired shift position, and means for opening and closing the solenoid valve in response to the command signal so as to obtain the desired shift position. In the above, the fluid pressure cylinder is a multi-position cylinder, and the space formed between the free piston and the shaft piston of the multi-position cylinder is communicated with the atmosphere through a throttle valve with a check valve. A transmission featuring:
