  • Patent number: 11333211
    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.

  • Patent number: 11242901
    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.

  • Patent number: 9822832
    Abstract: A disc brake device includes flat springs assembled in a support body and holding the brake pad back plates. The flat springs have a C-shaped part provided with: a connection surface part comprising a pad-receiving surface part; an outer circumferential surface part extending along the rotor circumferential direction from the end region of the connection surface part in the rotor radially outward direction; and an inner circumferential surface part extending along the rotor circumferential direction from the end region of the connection surface part in the rotor radially inward direction. Each flat spring also has a tongue-shaped part that: extends towards the connection surface part from the tip region of the inner circumferential surface part in the rotor circumferential direction; elastically engages an inner circumferential wall of a recess at a tip region of the tongue-shaped part; and biases the pad-receiving surface part towards a base wall of the recess.
