1. A transaxle with a brake comprising:
a transaxle casing;
an axle supported by the transaxle casing;
a continuously variable transmission disposed in the transaxle casing, wherein a motor shaft of the continuously variable transmission is supported by a motor supporting member; and
a braking device that is disposed in the transaxle casing and is configured to lock a rotation of the axle, wherein the braking device comprises:
a plurality of brake discs,
a plurality of fixing plates that are stacked alternately with the brake discs,
a brake operating member that presses the brake discs against a brake contact surface of each of the fixing plates and the motor supporting member, and
a stopper fixedly provided to the transaxle casing at a position facing the brake operating member,
wherein the brake discs have an inner gear tooth portion that are fitted to an outer gear tooth portion of an output gear of the motor shaft so as not to rotate relative to the outer gear tooth portion,
wherein the brake discs are slidably fixed in an axial direction of the motor shaft,
wherein the fixing plates are fixed to the transaxle casing so as not to rotate relative to each other and are slidably fixed in the axial direction of the motor shaft, and
wherein the brake operating member provides a predetermined gap between the fixing plates and the brake discs when the brake discs are not pressed.
