Abstract

Official abstract text for this publication.

A centrifugal clutch intermittently transmits power of rotation about an axis. The centrifugal clutch includes: a plurality of clutch shoes that are pressed against an inner peripheral surface of a clutch drum; a plurality of pivot members configured to rotatably support the clutch shoes; and a pressing member having a plurality of insertion portions that are inserted between head portions of the pivot members and the clutch shoes. The pressing member has a connecting portion that connects between the plurality of insertion portions, and the insertion portions and the connecting portion are curved in a direction of the axis.

First claim

Opening claim text (preview).

What is claimed is: 1. A centrifugal clutch that intermittently transmits power of rotation about an axis, the centrifugal clutch comprising: a clutch drum; a plurality of clutch shoes that are pressed against an inner peripheral surface of the clutch drum; a plurality of pivot members configured to rotatably support the clutch shoes; and a pressing member having a plurality of insertion portions that are inserted between head portions of the pivot members and the clutch shoes, wherein the pressing member has a connecting portion that connects between the plurality of insertion portions, the plurality of insertion portions and the connecting portion forming a curvature that extends between the plurality of insertion portions and along the entire connecting portion. 2. The centrifugal clutch as claimed in claim 1 , wherein the plurality of insertion portions and the connecting portion are curved inward in a direction of the axis. 3. The centrifugal clutch as claimed in claim 2 , wherein the plurality of insertion portions are provided with a plurality of insertion holes into which the pivot members are inserted. 4. The centrifugal clutch as claimed in claim 2 , wherein the plurality of insertion portions each have an arc-shaped portion formed along a portion, closer to the axis, of an outer periphery of each pivot member. 5. The centrifugal clutch as claimed in claim 1 , wherein the insertion portions and the connecting portion are curved outward in a direction of the axis. 6. The centrifugal clutch as claimed in claim 1 , wherein a gap between the head portions of the pivot members and the clutch shoes is a dimension G, and a plate thickness T of the pressing member is set within the range of 0.4G to 0.6G. 7. The centrifugal clutch as claimed m claim 1 , wherein a distance between axes of the pivot members is of a dimension D, and a radius of curvature R formed by the plurality of insertion portions and the connecting portion is set within the range of 2D to 4D.
