Claim 0:
1. A component supply device configured to feed a component having a through hole to a target position, the component supply device comprising:
a rod including at its distal end a holding portion to be inserted into the through hole, and configured to advance in an axial direction to feed the component to the target position;
an actuator configured to cause the rod to advance and withdraw in the axial direction;
a valve mounted on the rod and configured to advance and withdraw with the rod; and
a fixing portion that is configured not to advance and withdraw with the rod and by which the valve that advances with the rod passes, wherein
the rod includes
a gas outlet located in an outer periphery of the holding portion and configured to blow gas rearward in the axial direction, and
a gas passage extending in the axial direction inside the rod and configured to send gas supplied from a gas source to the gas outlet,

the valve includes
a push switch configured to be switched between an advanced attitude corresponding to an open state in which a gas channel from the gas source to the gas passage is open and a withdrawn attitude corresponding to a closed state in which the gas channel from the gas source to the gas passage is closed, and
a biasing unit configured to bias the push switch to the withdrawn attitude,

the fixing portion includes a pressing wall portion facing the push switch and extending in the axial direction, and
as the valve advances, the push switch advances along the pressing wall portion and is pressed by the pressing wall portion into the advanced attitude against a biasing force of the biasing unit before the component reaches the target position, and the push switch is released from the pressing wall portion and changed from the advanced attitude to the withdrawn attitude by the biasing force of the biasing unit after the component reaches the target position.
