Abstract

A valve-actuating lever for internal combustion engines with a slide member disposed in a rectangular groove which is form-lockingly retained at the lever member by at least two strips within the area of the forward and rear edge in relation to the direction of rotation of the cam shaft, whereby the lever member is provided with undercuts within the area of the rectangular groove; the strips thereby consist of fiber-reinforced plastic material with a temperature resistance of at least 150.degree. C. and form-lockingly surround the undercuts of the lever member as well as the forward and rear edge of the slide body in relation to the direction of rotation. It is preferred if the strips are constructed as closed frame.
