Abstract
A switch shaft connection shaft (24) is formed on a switch knob (22), and connected to a switch shaft (26). Therefore, the switch shaft (26) can move in response to an inclination restoration operation of the switch knob (22). Further, the switch shaft (26) has movement in the lateral direction regulated by a guide rail (17), which makes it possible to always exert pressing force vertically with respect to a tact switch (25). Moreover, a region where the tact switch (25) is pressed from the switch shaft (26) is constituted by a resilient member, which means that there is no striking noise when the switch shaft (26) strikes the tact switch (25), and it is possible to provide a switch unit that is quiet at the time of operation.
