Rocker switch device

A rocker switch device comprising a switch case that retains a fixed contact and can be joined to a support body, and an operating knob that retains a movable contact and is axially supported on the switch case so that the operating knob can swing, the switch case having a pair of mutually opposing side wall parts with the operating knob sandwiched therebetween, and a linking wall part providing a connection between base portions of the pair of side wall parts,

• wherein a pair of shaft portions are projectingly provided on mutually opposing faces of extremity portions of the pair of side wall parts, the pair of shaft portions being aligned on the same axis as each other, a bearing hole is formed in the operating knob so as to extend therethrough, the pair of shaft portions being rotatably fitted into the bearing hole, a projecting portion is provided on an outside face of at least one of the side wall parts, the projecting portion being pressed into contact with the support body to thus prevent rattling of the switch case, and the pair of shaft portions are formed so as to have a length such that mutually opposing extremities of the pair of shaft portions directly abut against each other.
