In a vehicle push button switch, movement of a push button is guided by multiple guide portions and backlash of the push button during a push operation thereof is thereby prevented, and operations of the push button are not hindered even when water attached to an outer surface of a bar-shaped portion of the push button freezes. The case is provided with a plurality of guide portions spaced away from each other in a peripheral direction of the bar-shaped portion to guide a plurality of sections of the bar-shaped portion that are located in the peripheral direction, and an ice scraping rib protrudes from an outer surface of the bar-shaped portion. The ice scraping rib scraps away a frozen ice portion formed by freezing of water attached to the outer surface of the bar-shaped portion between the plurality of guide portions, in response to movement of the bar-shaped portion.
