Because the coil spring 30 is composed of an urging portion 30C that urges the coil 4 in the closing direction, the coil spring main body 30A of the coil spring 30 and the urging portion 30C are caught by the stopper member 28 even when cut. In addition, it is possible to prevent the cut pieces from being carried out together with the carrying ice. In addition, the support part 30B is the base 18
However, the same operation is performed even if the ice storage 11 is in contact with the main body.

Next, in FIGS. 1, 8 and 9, a coil spring main body 30A wound around the rotating shaft 31 and a support extending from the coil spring main body 30A in the direction of the base 18 are shown. 30B, extending from the left and right ends of the coil spring main body 30A and being inserted into the space 35 of the stopper member 28 from the left and right to connect or integrally form the ends, and contacting the open / close door 14 to open / close the open / close door The coil spring 30 of the coil spring 30 includes a biasing portion 30C that biases the coil 14 in the closing direction.
Even if A and the urging portion 30C are cut, the cut pieces are caught by the stopper member 28, thereby preventing the cut pieces from being carried out together with the unloaded ice. The support portion 30B is not limited to the base 18, and performs the same operation even when it comes into contact with the ice storage 11 main body.

[0020]

According to the first aspect of the present invention, there is provided a relationship in which the end of the sprung body for attracting the moving shaft and the solenoid plunger is wound at least twice with respect to the solenoid plunger and the moving shaft. In addition , even if a part of the projectile is cut due to metal fatigue, the cut pieces are prevented from being carried out together with the carried-out ice, so that the reliability of the equipment with respect to the taken-out ice can be improved.

According to the second aspect of the present invention, since the intermediate member (collar) made of resin such as vinyl chloride is interposed between the coil spring and the rotation shaft, the coil spring and the rotation shaft are worn. In order to prevent the coiled strip from being cut due to metal fatigue and to prevent the cut pieces from being carried out together with the unloaded ice, it is possible to improve the reliability of the equipment with respect to the unloaded ice.

According to a third aspect of the present invention, there is provided a rotating shaft for rotating the opening and closing door, and an end wound around the rotating shaft, one end of which is in contact with the ice storage main body or the base and there is an interval between the ends. The other end extends from the left and right ends of the rotating shaft and is inserted into the space of the stopper member to connect the ends or be integrally formed, and contact the opening / closing door to close the opening / closing door in the closing direction. Due to the configuration of the coil coil to be energized, even if a part of the coil coil is cut, it will be caught by the stopper member. Can be improved.
