MASTER CYLINDER OPERATING MECHANISM

When a pushrod (23) slides inside a cylinder body (31) and a guiding member (36) in response to an operational input and then comes into contact with a stopper member (35) of the guiding member (36), the guiding member (36) receives a load that acts in a direction in which the pushrod (23) is pulled out of the guiding member (36). A surface of the guiding member (36) in contact with the dashboard (40) faces an engine compartment-side surface of the dashboard (40) in the direction in which the pushrod (23) is pulled out of the guiding member (36). Thus, displacement of the guiding member (36) in a direction in which the guiding member (36) comes out of the cylinder body (31) is restricted by the engine compartment-side surface of the dashboard (40).
