Claim:
1. A closer device comprising: a threaded shaft that rotates by drive force of a motor; an elongated member that threadedly engages with the threaded shaft to transmit decelerated rotation of the threaded shaft and permit displacement in an axial direction between a first axial position and a second axial position; a tubular member in which the elongated member is positioned, the tubular member and the elongated member being integrally rotatable with one another; a restriction member that is displaced between a first position at which the elongated member is displaced from the side of the first axial position to the side of the second axial position by restricting rotation of the elongated member that accompanies the rotation of the threaded shaft and a second position at which the displacement of the elongated member from the side of the first axial position to the side of the second axial position is restricted by permitting the rotation of the elongated member that accompanies the rotation of the threaded shaft; wherein the elongated member drives a locking member of a latch mechanism by being displaced from the first axial position to the second axial position; and wherein the restriction member is displaced from the first position to the second position in conjunction with an operation unit that is operated by a user.
