Abstract

PROBLEM TO BE SOLVED: To eliminate a play between a key top and a link member and restrict the generation of hitting noise by protruding the link member fitted to a slide groove with a spring member which elastically comes into contact with the back face of the key top and generates a repulsive force. SOLUTION: A spring member 6E is protruded and formed in parallel to a link member 6 from a press part provided for the link member 6. A cylinder- shaped runway part 6F is protruded above a shaft 6C, the runway part 6F comes into contact with the back face of a key top 8 when the shaft 6C is inserted into a slide groove 8B, the spring member 6E is elastically deformed, and a repulsive force P is generated. When a resistance force is applied to the key top 8 by utilizing the repulsive force P of the spring member 6E, the shaft 6C is pressed to a lower side wall face 8C in the slide groove 8B and held in a state free of a play. And, the repulsive force P of the spring member 6F is set more strongly than the resistance force of a dome-shaped body 5, the shaft 6C can be pressed to the lower side wall face 8C even during press operation.

FIG. 3 shows an embodiment corresponding to claim 2 of the present invention. A second aspect of the present invention proposes a configuration in which any one surface of the sliding groove 8B formed in the key top 8 is provided with a friction engagement means 8D that engages with the shaft 6C. In the embodiment shown in FIG. 3, an inclined surface is formed on the lower wall surface 8C constituting the sliding groove 8B, and the friction engagement means 8D is formed by this inclined surface.
Shows the case of configuring. The friction engagement means 8D is an inclined surface in the direction in which the frictional force increases as the key top 8 approaches the top dead center position. That is, as the key top 8 approaches the top dead center position, the shaft 6C moves upward due to the inclined surface and is sandwiched between the wall surface 8C and the facing ceiling surface. As a result, the key top 8 is sandwiched by the narrow portion of the sliding groove 8B at the top dead center position, and is maintained in a state without rattling.
