摘要： The present invention provides a disk brake capable of ensuring excellent actuation efficiency. A piston holding mechanism 34 mounted in a disk brake 1a includes a planetary gear speed reduction mechanism 36 configured to power up a rotation of a motor 38, and a screw mechanism 52 and a ball and ramp mechanism 28 configured to convert a rotation of the planetary gear speed reduction mechanism 36 into a linear motion to advance a piston 12 in parallel. The planetary gear speed reduction mechanism 36 transmits a rotational output provided by powering up an input from the motor 38 to the screw mechanism 52 or the ball and ramp mechanism 28, and transmits a reactive force of the rotational output to the screw mechanism 52 or the ball and ramp mechanism 28. The screw mechanism 52 maintains a braked state when a supply of a rotational force from the motor 38 is stopped. As a result, it is possible to ensure excellent actuation efficiency.

摘要： An object of the present invention is to provide a disk brake having excellent responsiveness. A rotation preventing mechanism 34A prevents a rotation of a carrier 41 (one output member) in a direction causing a piston 12 to return. An internal gear 46 (the other output member) rotates by a predetermined degree to act on the rotation preventing mechanism 34A. When the motor 38 causes a sun gear (input member) to rotate such that the piston 12 moves in a return direction, a rotation of the internal gear 46 according to the rotation of the sun gear 44 releases rotation prevention of the rotation preventing mechanism 34A to the carrier 41. It is possible to release the parking brake without use of a worm gear which is used in the conventional arts for holding a thrust force (self-holding). As a result, it is possible to quickly release the parking brake, and therefore a driver can start to run without delay after parking brake release, whereby the responsiveness is improved.

摘要： Provided is a disk brake improved in production efficiency by simplifying a structure for retaining the braking force of a parking brake. A disk brake is equipped with a piston holding mechanism having a ball-and-ramp mechanism in which balls are moved by rotation transmitted from a motor, causing a rotary-rectilinear ramp to press a piston. The rotary-rectilinear ramp has an external thread engaged with an internal thread formed on a base nut immovable in a rotor axis direction relative to a caliper body. The external thread, when a force is applied thereto from the piston in the rotor axis direction, can retain the position of the rotary-rectilinear ramp in the rotor axis direction. Thus, the structure for retaining the braking force of the parking brake can be simplified to improve the production efficiency.
