In this case, the feed screw 31 is rotated so that the moving member 32 moves to the rear side by inserting a tool such as a screw driver through the through portion 13a.

As the moving member 32 moves to the rear side, the elastic restoring force of the spring 33 is reduced while the spring is elastically restored.

On the contrary, when the front panel 22 is formed of a heavy material, the elastic restoring force of the spring 33 is smaller than the force acting by the weight of the door 20 in the state in which the door 20 is partially opened. Thus, the washing chamber 12a is completely opened while the door 20 falls by its own weight.

In this case, the feed screw 31 is rotated so that the moving member 32 moves forward by inserting a tool such as a screw driver through the through portion 13a.

As the moving member 32 moves forward, the spring 33 is elastically deformed, and the elastic restoring force of the spring 33 is increased.

Moving the moving member 32 back and forth as described above increases or decreases the elastic restoring force of the spring. Accordingly, when the moving member 32 is positioned at a position where the force acting by the self-weight of the door 20 and the elastic restoring force of the spring 33 are balanced by rotating the feed screw 31, the door 20 is partially. The open state can be maintained as it is.

In this embodiment, the rope holder 34 is installed on the rear flange portion 132 through the locking groove 34c and the locking projection 132a, but this is for not using a fastening member, the rope holder 34 is bolted It is also possible to be fixed through a fastening member such as.

In this embodiment, the door support device 30 includes a rope holder 34 so that a part of the elastic restoring force of the spring 33 is distributed to the side frame 13S, but this is to correspond to the heavy door 20. If the weight of the door 20 is light, the rope holder 34 may be removed.

In the present embodiment, the door support device 30 maintains the door 20 partially open as it is, but this is an example. The door support device 30 is adjusted to adjust the door support device 30 to the spring 33. It is also possible to make it close by the elastic restoring force of the door, or to make the door 20 fall gradually by its own weight.

The scope of the present invention is not limited to the specific embodiments described above. Various other embodiments which can be modified or modified by those skilled in the art without departing from the gist of the technical spirit of the present invention specified in the claims will also belong to the scope of the present invention.
