摘要： A rotary shaft and a rotation driven member are connected as to transmit motive power when the rotary shaft rotates relatively to the rotation driven member. A roller gets displaced to a first position where a frictional force with an outer race and the rotation driven member decreases, thereby permitting transmission of a rotational force from the rotary shaft to the rotation driven member. When the rotation driven member rotates relatively to the rotary shaft, the roller gets displaced to a second position where the frictional force with the outer race and the rotation driven member increases, thereby rotationally fixing the rotation driven member with respect to the outer race. The power transmission from a brake apparatus to an electric motor can be hindered while permitting the power transmission to the brake apparatus from the electric motor by using either a worm exhibiting a relatively low transmission efficiency or a worm wheel.

摘要： A ball screw mechanism that can drive a movable pulley disk in an axial direction includes a screw cylinder and a nut member. A stopper pin is inserted through the screw cylinder from one end surface of the circumferential wall of the screw cylinder to the other end surface. As an end portion of the stopper pin is engaged with a notch portion of a transmission case, the rotation of the screw cylinder is inhibited. A stopper projection is provided on the nut member. As the other end portion of the stopper pin abuts against the stopper projection, the rotation range of the nut member is regulated. The stopper projection and the stopper pin function as excessive fastening preventing means for preventing the excessive fastening of the ball screw mechanism.

摘要： A rotary shaft (3) and a rotation driven member (4) are so connected as to be capable of transmitting motive power when the rotary shaft (3) rotates relatively to the rotation driven member (4). A roller (6) gets displaced to a first position where a frictional force with an outer race (5) and the rotation driven member (4) decreases, thereby permitting transmission of a rotational force from the rotary shaft (3) to the rotation driven member (4). When the rotation driven member (4) rotates relatively to the rotary shaft (3), the roller (6) gets displaced to a second position where the frictional force with the outer race (5) and the rotation driven member (4) increases, thereby rotationally fixing the rotation driven member (4) with respect to the outer race (5). The power transmission from a brake apparatus (e.g., a parking brake apparatus) to an electric motor (2) can be hindered while permitting the power transmission to the brake apparatus from the electric motor (2) by using neither a worm exhibiting a relatively low transmission efficiency nor a worm wheel. In a state where the brake apparatus exhibits its braking force, the roller (6) receives the force from the brake apparatus and is thereby biased toward the second position, whereby a construction of a power transmission mechanism (50) can be simplified and costs can be reduced to such an extent.
