Abstract

PURPOSE:To provide a takeout tool for an insert metal fitting which easily separates the insert metal fitting from a plastic part into which the insert metal fitting is pressed. CONSTITUTION:A slidable heater member 32 is arranged to the inside of unfoldable lock claws 21. In a state that the lock claws 21 are folded, the lock claw 21 is inserted in an insert fitment on the inside of which a female screw is formed. When a heater member 32 is slid from this state to unfold the lock claws 21, a lock tooth 22 formed on the outer periphery of the lock claw is engaged with the female screw. The heater member 32 is electrically heated through a source cord 33, the insert metal fitting and the joining part of a sheathing member are fused through the lock claws 21 to loosen an engaged state. Thus, by lifting the lock claws 21 from the state, the insert metal fitting is easily pulled out from the sheath member and separated.
