Claims

[Scope of utility model registration request]

It consists of a fixed pulley piece and a movable pulley piece attached to the fixed pulley piece so as to be freely movable in the axial and rotational directions on the axial extension of the fixed pulley piece. A coil spring is provided between the two locking portions, with a locking portion provided on the side thereof and one side of the movable pulley, and the end of the coil spring is pressed against each locking portion. When the belt is suspended in the groove formed between the fixed pulley pieces and travels, the shaft of the fixed pulley piece of the variable speed pulley is interposed so that a load is generated in the direction of unwinding due to the torque generated on the movable pulley piece. Further, an inward piece is provided on the extension part integrally with the shaft, and an outward piece facing the inward piece is provided on the boss part of the movable pulley piece, and an inverted ■-shaped groove is formed by these inner and outward pieces,
A plurality of balls are interposed in the inverted ■-shaped groove, and the movable pulley piece is pressed against one side of the fixed pulley by the centrifugal force generated on the balls according to the rotation speed of the variable speed pulley, and the force combined with the repulsive force of the coil spring. 1. A rotation-sensitive transmission device characterized in that a speed change pulley as described above is used on at least one of the driving side and the driven side, and a belt is suspended between the other pulley and the other pulley.
