Abstract
A mechanical component configured to rotate with a shaft member includes a component main body having a through-hole through which the shaft member is passed, and one or more shaft support portions formed on the inner surface of the through-hole to fix the shaft member to the component main body. The one or more shaft support portions protrude from the inner surface of the through-hole and are capable of retaining the shaft member due to an elastic force. The one or more shaft support portions are made of material having a larger elongation percentage than that of the material of the component main body thereby preventing breakage of the mechanical component due to stress created when the shaft member is forced through the through-hole in the component main body.
