Abstract: A motion conversion mechanism of a brake device includes a rotation member and a linear motion member that linearly moves accompanying the rotation of the rotation member. The rotation member is rotationally driven through a third gear. A male screw and a female screw mesh with each other on the side opposite to the brake shoe of the third gear, where one end of an actuating member receives a force for actuating the brake shoe from the linear motion member, and the other end actuates the brake shoe. The guide member that guides the actuating member is made of a material different from that of the rotation member, and slidably guides the actuating member in the axial direction.

Abstract: A pad support spring includes a U-shaped portion comprising an outer peripheral surface portion, an inner peripheral surface portion and a linking surface portion. The U-shaped portion is configured to include: a pad holding portion; a cutout portion provided by cutting out a part from the linking surface portion toward the inner peripheral surface portion; a tongue piece portion which in an unassembled state has a base end formed by the cutout portion on the outer peripheral surface portion side of the pad holding portion and a distal end which projects out from an opposing surface of the inner peripheral surface portion, and which in an assembled state deforms elastically to press a brake pad in conjunction with the U-shaped portion; and a first slit portion provided by cutting out part of a first linking part.
