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.

A ball screw groove of the screw shaft is formed having a loaded surface which is pressed against the balls, on the side of a groove base in the first axial direction. A ball screw groove of the nut member is having a loaded surface which is pressed against the balls, on the side of its groove base in the second axial direction. These loaded surfaces are finished so that their surface roughness is lower than that of the unloaded surfaces.

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 frictional transmission comprises first and second rotary shafts arranged in directions in which the central axes thereof crossed each other, a roller supported coaxially with the first rotary shaft for rotating with the first rotary shaft, a first frictional surface provided on the roller coaxially with the first rotary shaft, a disc supported coaxially with the second rotary shaft for rotating with the second rotary shaft, and a second frictional surface provided on this disc coaxially with the second rotary shaft. The second frictional surface and the first frictional surface are brought into frictional engagement with each other. A loading cam device is arranged so as to press the second frictional surface toward the first frictional surface at the time of driving. A further disc coaxial with the aforementioned disc is disposed in the environs of the second rotary shaft, and the roller is sandwiched by and between the two discs. This further disc is rotatably supported by an angular-type ball bearing relative to the second rotary shaft and the first-mentioned disc in the environs of the second rotary shaft in a state that this further disc is prevented from being displaced in a direction to be separated from the first-mentioned disc.
