  • Mechanism for adjustment of vehicle operating lever
    Patent number: 8141691
    Abstract: An operating lever, for example for use in a vehicle, is provided. The operating lever may comprise a lever holder, and an operating component pivotably coupled to the lever holder. Manipulation of the operating component may regulate or control a “pulling margin” of a wire that operates a device such as a clutch. The operating component and the lever holder may contact each other circumferentially at a contact portion. At the contact portion, projections on respective surfaces of the operating component and lever holder may engage each other in such a way that when the operating component is turned to regulate the pulling margin, the operating component undergoes elastic deformation in a radial direction. In this way, a definite operating feel is transmitted to a person operating the operating component.
