摘要： A caliper brake device includes a brake caliper (10), a movable brake pad (7), pistons (55), and a guide member (65). The brake caliper (10) has a first caliper arm (12) facing a first friction surface (6a) of a wheel (5), and also has a second caliper arm (14) facing a second friction surface (6b) of the wheel (5). The movable brake pad (7) is supported on the first caliper arm (12) and applies braking force to the first friction surface (6a) by moving toward the first friction surface (6a). The pistons (55) drive the movable brake pad (7) in response to expansion of a diaphragm (75) in the brake caliper (10). The guide member (65) guides movement of the pistons (55) in the direction perpendicular to the first friction surface (6a). The brake pad (7) uniformly applies braking force to the wheel (5) in cooperation with a fixed brake pad (700) supported on the second caliper arm (14).
