Abstract
A cam portion is composed of a first to fifth arcuate surfaces to . The first arcuate surface is arranged such that when a cover member C of a cellular telephone is located in a neutral position, a plate spring portion contacts a crossing portion where the first arcuate surface crosses an orthogonal line Lp passing through a center of curvature of the first arcuate surface and orthogonal to a rotation axis L. A second and a third arcuate surface are arranged on both sides of the first arcuate surface . Radii of curvature of the second and third arcuate surfaces are set to be larger than a radius of curvature of the fist arcuate surface
