A linear reciprocating-motion apparatus that can further improve reliability by simplifying electrical circuitry related to a switch is provided. A linear reciprocating-motion apparatus (1) comprises: a housing (90); a movable member (10, 30) that is supported by the housing (90) and is capable of undergoing linear reciprocating motion in a range that includes a first position, a second position, and a third position; a stopper (50) that is supported by the housing (90), is displaceable between a blocking position at which movement of the movable member (10, 30) from the second position to the first position is prohibited and a nonblocking position at which movement of the movable member (10, 30) from the second position to the first position is permitted, and is displaced to the nonblocking position in response to a specific operation; an intermittent mechanism (100, 200) that interacts with the linear reciprocating motion of the movable member (10, 30) and assumes a specific state once every two times when the movable member (10, 30) repeats the action of moving to the third position; and a switch (SW1) that, when the specific state is assumed, is switched from one of a disconnected state and a connected state to the other of the disconnected state and the connected state.
