    Abstract: A housing has a screw shaft passing wall in which a through hole, through which a screw shaft passes, is formed. A spline outer cylinder is held at one end by the screw shaft passing wall, and a disc spring that biases the spline outer cylinder toward the screw shaft passing wall is arranged at the other end of the spline outer cylinder. A tapered recess is formed in one end face of the spline outer cylinder, and a tapered projection that is fitted in the tapered recess is formed in a face of the screw shaft passing wall of the housing, which faces the spline outer cylinder.

    Abstract: A universal joint including an intermediate joint member having a spherical portion as assembled and four ridges formed on the outer surface of the spherical portion and defining four guide furrows therebetween, and two shaft each having one end bifurcating into two arms. The two arms of one of the shafts are fitted in two of the guide furrows positioned symmetrically, and the two arms of the other shaft are fitted in the other two guide furrows positioned symmetrically. The entire joint member comprises two divided half segments arranged in combination axially of the member. Alternatively, the spherical portion comprises two divided half segments arranged in combination axially thereof, one of the spherical half segments being integrally formed with two of the ridges positioned symmetrically and extending to over the outer surface of the other spherical half segment, the other spherical half segment being integrally formed with the other two ridges positioned symmetrically and extending to over the outer surface of said one spherical half segment. In either of these arrangements, an elastic member is provided at the combined portion of the two segments inside the contour of the combined portion for biasing the segments at least circumferentially thereof out of register with each other.

    Abstract: A belt tensioner comprising an intermediate annular member rotatably provided around a fixed member in the form of a solid cylinder and to be secured to a stationary portion, a movable eccentric member in the form of a solid cylinder and rotatably provided around the intermediate annular member eccentrically therewith, an idler in the form of a hollow cylinder and rotatably provided around the movable eccentric member for contact with a belt, and a spring provided between the stationary portion or the fixed member and the movable eccentric member for biasing the movable eccentric member in a direction to bring the idler into pressing contact with the belt. The intermediate annular member has a cylindrical or tapered first sliding surface in contact with the fixed member and a cylindrical or tapered second sliding surface in contact with the eccentric member. One of the first and second sliding surfaces of the annular member is a high-friction sliding surface, and the other surface is a low-friction sliding surface. An oil of high viscosity is provided between the low-friction sliding surface and the surface of the fixed member or the eccentric member in contact therewith.
