An insertion tool according to the present invention comprises a shaft part that, by being inserted through a hole in a fixture, protrudes in the direction from the tip of the fixture toward the tip side and an air supply channel that is formed on the shaft part and has, on a tip part of the shaft part, a blowout port for blowing out air. Air is supplied by the air supply channel from a base end side to the tip side toward the blowout port and the extension dimension of the air supply channel along the lengthwise axis from the blowout port to the base end side is larger than the extension dimension of the hole in the fixture. |
