ABSTRACT:
A U-shaped spring member is placed on the outer periphery of a hollow cylindrical part of an operating body. Engaging portions in arm portions upwardly inwardly extending from both ends of the spring member are fitted into holes through the hollow cylindrical part and brought into resilient contact with a groove on the outer periphery of an operating shaft. This structure provides a switch device that has great resistance to pull-out of the operating body for secure fastening thereof and is easy to assemble.
