Abstract
PURPOSE: To lighten a change cam by forming a cam body with a lead groove by a light material such as a resin base material in a transmission for an autobicycle.
CONSTITUTION: A change cam 10 is divided and made up into a cam body 11 consisting of a light material, such as a resin base material, a light alloy material or the like, while a bearing section 13 being composed of an iron base material and a changing force transmitting section 14, and these bearing section 13 and changing force transmitting section 14 are welded or pressed in to both ends of the cam body 11 and unified. A lead groove 12 is built up on a circumferential surface of the body 11. Thus, the change cam can be lightened because the sections, to which strength and abrasion resistance are needed comparatively, of the both ends are formed by the iron base material and other most sections including the lead groove 12 are made up by the light material, such as the resin base material, the light alloy material or the like.
