The door 11 is attached to the frame 9 by this.

As described above, in the present embodiment, the outer surface 11A of the door 11 (the outer surface 13a of the one-side member 13) is curved along the direction of rotation of the door 11. Even if it rotates from the closed state indicated by the solid line toward the closed state indicated by the two-dot chain line, and even if it rotates from the open state toward the closed state, the outer surface 11A of the door 11 and the The width of the gap S with the left vertical frame 3 (the distance between the outer surface 11A and the left vertical frame 3) can be made constant. As a result, as shown in FIG. 8, even if the door 11 is opened and closed while the finger is in contact with the gap S, it is possible to prevent the finger from being caught in the gap S.

In addition, since the outer surface 13a of the one side member 13, which is a molded product separate from the door body 12, is used as the outer surface 11A of the door 11, the outer surface of the plate-like door body 12 is chamfered. etc. are unnecessary, and the door 11 having a curved outer peripheral surface can be easily manufactured.

Further, the holding portion 45 alone with which the second shaft 43 is integrally provided has a function of receiving and supporting the door 11, a function of attaching the second shaft 43 to the frame body 9, and a part of the rotation shaft of the door 11. It is possible to demonstrate various functions such as the function of

Further, since the first shaft 35 that can move back and forth is provided on the upper surface 11b of the door 11, and the second cylindrical portion 41b through which the second shaft 43 can be inserted is provided on the lower surface 11c of the door 11, The door 11 can be attached to the frame body 9 by a simple work of lowering the pushed-up door 11 as it is.

Further, by setting the length L3 in the extending direction of the shaft fixing piece 45b constituting the holding portion 45 to be shorter than the length in the extending direction of the second fixing piece 45a constituting the holding portion 45 (L3< L4), since the load of the door 11 applied to the shaft fixing piece 45b is distributed to the second fixing piece 45a, the shaft fixing piece 45
The load on b is reduced. As a result, rattling of the holding portion 45 due to deterioration over time can be reduced. The same can be said for the first shaft support portion 33, which is composed of the bearing piece 33b and the first fixed piece 33a whose length L2 is shorter than the length L1 of the bearing piece 33b.
