Abstract
There is proposed a nail driving tool provided with a driver guide including an injection hole for driving a nail and a contact arm surrounding an outer surface of a forward end of the driver guide in a nail driving direction, provided with an eject hole penetrating through the contact arm, movable on an axial line along the nail driving direction for making triggering operation for driving a nail effective by being moved in the opposite direction to the nail driving direction and designed to drive a nail outwardly through the eject hole, wherein a diameter of an outer surface of a forward end portion of the contact arm is decreased taperingly toward its edge in the nail driving direction. A diameter of the eject hole of the contact arm in the vicinity of the forward end of the contact arm in the nail driving direction is nearly equal to that of the injection hole of the driver guide in the vicinity of the forward end of the driver guide in the nail driving direction and an outer diameter of the contact arm in the vicinity of the forward end of the contact arm is equal to or smaller than an outer diameter of the driver guide in the vicinity of the forward end of the driver guide. A spike is provided on the outer surface of the forward end portion of the contact arm for preventing slippage of the contact arm when a nail is driven obliquely. It is easy for the user of the nail driving tool to see and aim at the point to drive a nail.
