<P>PROBLEM TO BE SOLVED: To provide a belt-driven continuously variable transmission capable of preventing damage in the rotation of a primary pulley while preventing earlier damage of the shaft bearing unit which freely rotatably supports at least the primary pulley to the change gear case. <P>SOLUTION: A projection 76 for an oil receiving surface is provided on the outside surface of a cylinder member 43, and the projection 76 is extended circumferentially over it, so that the cylinder member 43 is formed so that the shaft bearing 34 is situated radially internally against the projection 76. Further, a projection 67 for the oil receiving surface is provided on the opposed surface of a fixed sieve 40 which faces the shaft bearing 35, and the projection 67 is extended circumferentially along the fixed sieve 40 and the fixed sieve 40 is provided so that the shaft bearing 35 is situated radially internally against the projection 67. <P>COPYRIGHT: (C)2009,JPO&INPIT |
