A folding part 3b on which stress is concentrated, and thickness of a portion is made thin in a uniform state over whole width of the tab 3, so that the folding part is folded easily between the snap 2 and the rear end, is provided. The rear end is provided on one side of the tab 3, and a top pushing end 3c is provided on an opposite front end. The can top plate 1 comprises a fulcrum 5 for supporting the can top plate 1 and the tab 3 in an approximately parallel state between the rear end of the tab 3 and the folding part 3b on an apex projecting from the can top plate 1 in a mountain-state.
