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.
