Claims

[Claims for Utility Model Registration] (1) A rim having an annular groove that can be engaged with a power transmission means, a hub having a shaft hole that can be engaged with a shaft that receives the transmitted power, and the rim and the hub. and a pulley seat is attached to the web for reinforcement coaxially with the hub, and a pulley is provided with a plurality of through holes for dynamic and static balance adjustment. The pulley seat is formed into a modified regular polygonal shape having a concave outer peripheral edge facing radially inward, or a shape similar to this, and the through hole in the web is formed at the outermost radially outer edge of the pulley seat. A pulley, characterized in that the pulley is located at a position separated from a contour line formed by projecting tangent lines connecting adjacent peripheral edges onto the web surface. (2) Consisting of a rim having an annular groove that can be engaged with a power transmission means, a hub having a shaft hole that can be locked to a shaft that receives the transmitted power, and a web that connects the rim and the hub. , a pulley in which a pulley seat is attached to the web for reinforcement coaxially with the hub, and a plurality of through holes are provided for dynamic and static balance adjustment, the pulley seat having a radius It is formed into a circular shape, a regular polygonal shape, or a modified regular polygonal shape similar to these, with an outer peripheral edge that is convex outward in the direction, and the through hole in the web is formed at the outermost peripheral edge in the radial direction of the pulley seat. A pulley characterized in that the pulley is located at a position separated from a contour line formed by projecting a line onto a web surface.
