動する。 A guide lever 1 is swingably supported on the outer periphery of the back of the movable face 7 by a tangential support shaft 12.
Place 3. The guide lever 13 extends in the centripetal direction and has an elongated hole 14 extending parallel to the support shaft 12 along the longitudinal direction of its inner half. The centrifugal roller 15 is separated into two parts and connected by a rod 16 with a slight distance between them, with a circumferential groove 17 formed in the center. The circumferential groove 17 is fitted into the elongated hole 14 to slidably support the centrifugal roller 15 on the guide lever 13;

し易く、特に高速時には擦り力も大きくなり重錘
の高速位置（Ａ部）での摩耗が大きかつた。 When the rotation of the drive shaft 1 increases and the tube shaft 2 rotates via the starting clutch, the fixed and movable faces 6,
7 rotate together and transmit power to a driven V pulley (not shown) via a V belt 8. When the rotational speed further increases, the movable face 7 is pushed by the centrifugal force of the centrifugal roller 15, the diameter of the V-pulley increases, and finally, as shown in FIG. 5, power is transmitted at high speed. When such a centrifugal weight accelerates,
During deceleration, force is applied to the weight in the rotational and counter-rotational directions due to rotational fluctuations, causing the weight to vibrate from side to side, resulting in strong friction between the elongated hole 14 of the guide lever 13 and the rod 16. This rubbing causes wear on the contact part, but since the elongated hole 14 and the rod 16 are in line contact and the contact area is small, the influence of rubbing is large and wear is likely to occur.Especially at high speeds, the rubbing force becomes large and the high speed position of the weight (A part) had a large amount of wear.

A rectangular guide hole 19d into which the guide piece 18b of the guide lever 18 is fitted is passed through the center of the shaft 19a, and this guide hole is formed on the circumferential surface of the shaft 19a. A guide surface 19e is provided parallel to 19d.
