Abstract
A switching device capable of preventing entrance of water from outside of a case through a space below an operation knob into the case is disclosed. The switching device includes: a switch; a case within which the switch is accommodated; a hollow cylinder which is formed integrally with the upper surface of the case and open to above and below to communicate with the inside of the case; an operation knob provided to cover an upper opening of the cylinder such that the operation knob can swing; and an operation bar which extends through a lower opening of the cylinder into the case to transmit the motion of the operation knob to the switch. A concave is formed on the upper surface of the case at a position around the cylinder. A lid for covering a part of the concave is provided on the concave near the cylinder.
