According to the invention having such a feature, when the driving means is driven so that the protruding portion moves upward, the first operating portion of the operating member moves upward, and the operating member swings around the fulcrum. The second actuating part of the actuating member moves the engaging part (second engaging part) of the open / close door to bring the open / close door into a closed state. On the other hand, when the driving means is driven so that the protruding portion moves downward, the first operating portion of the operating member moves downward, the operating member swings around the fulcrum, and the second operating member is moved. The operating portion moves from the closed state to the open state by moving the engaging portion (first engaging portion) of the open / close door.
In this way, the drive means can swing the operating member about the fulcrum to change the door from the closed state to the open state, or from the open state to the closed state. Unlike a door, there is no need to embed a weight in the door to open it. Therefore, there is no need to devise a way to hide the weight of the door as in the prior art, and the design of the door is not restricted. The beauty around the door can be improved.
[0006]
In this case, the opening and closing door is extended toward the second actuating portion engaged with the engaging portion (projection to project on the back side of the door) and a second engaging portion (driving means of the actuating member Arm), and the second actuating member of the actuating member moves the engaging part of the open / close door to bring the open / close door into the open state, and the second actuating part is the first of the open / close door. It is desirable that the two doors are brought into contact with the engaging portion to be closed from the open position.
[0007]
[0008]
Further, since the end of the first operating part is set on the upper surface of the projecting part based on the weight of the first operating member, the operating member is centered on the fulcrum by the weight of the first operating part. And the second actuating part of the actuating member moves the engaging part of the open / close door to change the open / close door from the closed state to the open state. As a result, the door is smoothly opened from the closed state, and unlike the conventional technology, there is no need to embed a weight in the door to open the door, so that the weight of the door can be hidden. It becomes unnecessary to apply. Therefore, the degree of freedom in the design of the door can be increased, and the aesthetics around the door can be improved.

Then, in a state where the open / close door 39 is closed, the second actuating portion 59 having a rounded tip is brought into contact with the second engaging portion 61 of the open / close door 39 on the lower surface 59a side ( (See FIG. 4A).
Then, when the open / close solenoid 54 is driven to move the plunger 54a downward from the upper position with the open / close door 39 closed (see FIG. 6B), the crank 55 swings around the fulcrum 57. (See FIG. 6C). Then, the second actuating portion 59 pushes and moves the first engaging portion 60 of the open / close door 39 on the front surface 59b side so that the open / close door 39 is opened from the closed state. Also in this case, since the second operating portion 59 is in contact with the second engaging portion 61 of the open / close door 39 on the rear surface 59c side with the open / close door 39 opened, the rear surface 59c The open / close door 39 is held in the open position (see FIG. 6C).
[0028]
On the other hand, when the open / close door 39 is opened (see FIG. 6C), the open / close solenoid 54 is driven to move the plunger 54a upward from the lower position (see FIG. 6A). The operation part 58 moves upward from the lower position. Then, the crank 55 swings around the fulcrum 57, so that the second operating portion 59 of the crank 55 pushes and moves the second engaging portion 61 of the open / close door 39 to open the open / close door 39 (see FIG. 4 (A)) to a closed state (see FIG. 4 (B)). In this case, the front surface 59b of the second operating portion 59 abuts on the first engagement portion 60 of the open / close door 39 , and the open / close door 39 is held in the closed position by the front surface 59b.
As a method for setting the first operating portion 58 of the crank 55 to be heavier than the second operating portion 59, it is not always necessary to provide the weight portion 58a to which the metal rod X1 or the like is attached. For example, as shown in FIG. The shape of the first actuating portion 58 may be increased and become heavier.
