PURPOSE:To improve resistance to vibration and durability, by a method wherein the securing member of a transmission mechanism is coupled to a static member through a buffering member. CONSTITUTION:A buffering member 21 is located between a stationary plate 11, forming a stationary member for a planetary continuously variable transmission mechanism, and a boss 1b forming the static member of an engine. The buffering member 21 is formed with a metallic bush 21a with a seat, situated at the inner side, and a bush 21b with a seat, e.g., rubber material, combined with the outer periphery of the bush 21a. As a result, the vibration modes of a crank shaft 1a and a boss 1b and relative vibration due to a phase difference enable reduction of extroadinary vibration, exerted on a driving device for an auxiliary machine by buffering action of the buffering member 21. Besides, even if strain and disorder of some degree on position accuracy of the crank shaft 1a and the boss 1b are produced, the buffering member 21 is deformed to absorb the strain and disorder, and this enables elimination of application of all strain on a device.
