A clearance is set between a nail feeder and an outer profile portion so that the nail feeder can turn. A pin as a first restriction member that inhibits movement of the nail feeder to an ejection portion by engaging with the nail feeder and can release the engagement with the rotation of the nail feeder is provided to the outer profile portion. The position at which the nail feeder and a spring engage is set in deviation from the position at which the nail feeder and the pin engage, in a reciprocating direction of the nail feeder and in a vertical direction.
