PROBLEM TO BE SOLVED: To reduce an axial length of a brake device while disposing a stopper member for regulating a stroke amount of a piston, in a brake device of a transmission including a first piston and a second piston.SOLUTION: A brake device (L-R brake 60) of a transmission includes a first piston (piston 66 for adjusting clearance) and a second piston (piston 65 for pressing). An oil passage 63 for supplying and discharging an oil pressure to a second hydraulic chamber (A chamber 61) is opened on an inner peripheral face of a transmission case 3, and an opening portion 612 for communicating the second hydraulic chamber and the oil passage, is formed on an intermediate position in the axial direction, of the first piston. A stopper member 160 for regulating a position of the first piston by being kept into contact with an edge portion 674 of the opening portion when the first piston is moved in the direction to be close to a multiple disc brake 69, is disposed on the inner peripheral face of the transmission case. |
