摘要： A ball-and-ramp mechanism of a thrust generator includes a rotary ramp member and a rectilinear ramp member, each having a plurality of sloped grooves sloped along a circumferential direction and having an arcuate diametrical cross-section, and a spherical member interposed between the sloped grooves of the ramp members to transmit force from the rotary ramp member to the rectilinear ramp member. Each of the sloped grooves has regions varying in the curvature radius of the diametrical cross-section in a track area where the spherical member contacts the sloped groove. Accordingly, it is possible to improve the durability of the rotary ramp member and the rectilinear ramp member.

摘要： In an electric brake of the present invention, a plunger of an actuator is connected through a pin to a pivot arm to which an engaging pawl engageable with a tooth portion of a ratchet is pivotably attached. A lower surface (a force-receiving portion) of the pin is adapted to receive an upward force which is applied by a tool inserted through a bolt hole threadably engaged with a watertight bolt. When the parking brake is operated (the engaging pawl is engaged with the tooth portion of the ratchet), if supply of current to the coil becomes impossible, the pin is moved upward by means of the tool, to thereby separate the engaging pawl from the tooth portion. Therefore, an emergency action to release the parking brake can be manually conducted.

摘要： The present invention provides an electric disk brake which enables an operation for wiring the harness to be easily conducted without the risk of lowering production efficiency. A caliper body-side connector 26 which, together with a harness-side connector 24 of a harness 23, forms a connector 25, is provided in a caliper body 3. In the caliper body-side connector 26, first to fourth lead-out terminals 30a to 30d connected to an electric portion for an electric motor are arranged in this order from a first side portion 20a towards a third side portion 20c of a cover 20. In the harness-side connector 24, a first set of first to fourth harness-side terminals and a second set of first to fourth harness-side terminals independently connected to the first to fourth lead-out terminals 30a to 30d are arranged in reverse order. When an electric disk brake 1 is used for each of the left rear wheel and the right rear wheel, one of the first set of first to fourth harness-side terminals and the second set of first to fourth harness-side terminals is used for the left rear wheel while the other is used for the right rear wheel, and the first to fourth lead-out terminals and the first to fourth harness-side terminals are connected. The harnesses 23 extend in the same direction relative to the vehicle, thus ensuring ease of operation for wiring the harnesses 23.

摘要： One of brake pads 5 is pressed against the disc rotor D by a piston of a caliper 3 which is floatably supported on the carrier 2, and in reaction thereto, the other brake pad 5 is pressed against the disc rotor D by a claw portion 14 on the caliper 3, thereby producing a braking force. During brake release, the spring force of a return spring 22 separates the brake pad 5 from the disc rotor D. A positioning convex portion 27 is provided on the carrier 2 in a standing position adjacent to the return spring 22, and serves to restrict the sideward movement of the distal end portion of the return spring 22. Thus displacement and deformation of the return spring can be prevented, and its functions can be maintained.

摘要： A motor-driven disk brake has a first brake pad and a second brake pad disposed at opposite sides of a disk rotor, a piston disposed so as to face the first brake pad, a claw portion extending over the disk rotor and facing the second brake pad, and an electric motor disposed in the vicinity of the piston. A ball ramp mechanism for converting rotation of the electric motor to a linear motion is disposed between the first brake pad and the electric motor. When the motor is operated, the piston is reciprocally moved by the ball ramp mechanism, to thereby enable application and removal of a braking force relative to the disk rotor by the brake pads.
