Abstract: 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.

Abstract: A system for transmitting power from a driving, or input, shaft to a driven, or output, shaft by way of an elastomeric belt nipped between opposing surfaces associated with the driving and driven shafts utilizes opposing surfaces which define a plurality of indentations disposed thereacross. Each indentation of the surfaces includes a cavity for accepting a portion of the elastomeric belt as the belt passes between the opposing surfaces and as edge which borders the cavity at the corresponding surface. As power is transmitted from the driving shaft to the driven shaft, significant shear and normal forces are applied between the edges of the indentations and the portions of the belt accepted by the indentations.

Each actuator can be similar having a cylinder and a shaft and annular pistons located about the shaft. For the rotational movement of the selector three positions are required, a neutral, a gear engaged position in one direction and a gear engaged position in the other direction. For movements in the direction of the axis two, three or four positions are required depending upon whether it is a two, three or four rail gearbox.
