Claims

[Scope of utility model registration request]

A drive-side pulley and a driven-side pulley having a fixed sheave and a movable sheave arranged opposite to each other on a drive shaft driven by an engine and a driven shaft that drives an engine accessory, and a movable sheave on one of the drive-side and driven-side pulleys. a spring that biases the fixed sheave in the direction thereof, a belt wound between the driving side and driven side pulleys, and a belt attached to the driving side and driven side pulleys so as to move together with the other movable sheave. In an engine accessory drive device comprising a flyweight inserted between opposing guide cam surfaces consisting of a tapered plate and a plate with a fixed shaft so as to be moved radially outward by the action of centrifugal force, the flyweight is fixed. An engine auxiliary equipment drive device having a rotating shaft, wherein the flyweight is rotatably supported by a bearing device between the opposing guide cam surfaces around the rotating axis.
