Abstract
In a vehicle caliper brake device, a brake pad supported by a holder applies a frictional force to a braking surface as a diaphragm actuator is driven. The holder is supported by a caliper main body to be capable of displacing in a displacement direction of the brake pad. The diaphragm actuator includes a piston that is driven by a diaphragm to push the holder. The piston is fixed to the holder using a plurality of screws, and therefore the piston applies a pressing force to the brake pad uniformly without the need for guidance by a guide.
