The caliper brake device is provided with: a guide plate for supporting a brake shoe; anchor pins for supporting the guide plate and which are provided on the main caliper body so as to advance and retract freely; a piston provided on the main caliper body so as to advance and retract freely; a piston plate that is secured to the piston and is supported by the anchor pins; an elastic membrane provided so as to define a pressure chamber inside the main caliper body and which moves the brake shoe by means of the piston, piston plate and guide plate; and a middle member disposed between the piston plate and the guide plate. By the middle member being interposed between the piston plate and the guide plate, a gap is formed between the piston plate and the guide plate.
