<p>PURPOSE:To aim at miniaturization for a motor and a device by making force, which energizes a brake pad and a disc so as to be engaged for braking, work to be doubled, in case of a disk brake assembly being operated by the motor. CONSTITUTION:Brake pads 11 and 12 have planes 13 and 14, and set up each in opposed relationship on an opposed surface of a brake disc 10 in an ordinary method, while these planes 13 and 14 are installed to be engaged with other planes 15 and 16. The brake pad 12 is installed on an arm 17 of a yoke 18 which bestrides an end of the brake disc 10 and has the opposition arm 19 set up on the opposed side of the brake disc 10 from the arm 17. The brake pad 11 is made to be drictionally engaged with the plane 15 of the brake disc 10 by a reversible motor 28 which has a shaft 30, and this shaft 30 is movable end to end within the limited range and it is provided with a thread ridge.</p> |
