With reference to FIG. 9 and FIG. 2, posture change in the retracting operation of the fitting 10 will be described. In the retracting operation, the user applies force R in the anti-sliding direction to the door body, so that the fitting 10 changes from the third state to the first state via the second state.

In the process from the second state to the first state, the door body goes through the processes shown in FIGS. 9(A) and 9(B). In the second state, when a force R in the anti-sliding direction is applied to the first door body 1, the first door body 1 moves toward the door bottom, and the engaging member 34 moves away from the door tip 21 of the second groove portion 52. The second groove portion 52 is moved obliquely forward while being in contact with the slope 524 on the opposite side.

When a force R in the anti-sliding direction is applied to the first door body 1 while the engaging member 34 is in contact with the slope 524 , a component force G of the force R is applied to the slope 524 . As a result, the door tip side of the second door body 2 is moved obliquely rearward by the component force G. As shown in FIG. As a result, the second door body 2 wraps around to the rear side of the first door body 1, resulting in the state shown in FIG. 9(B). Further, when a force R in the anti-sliding direction is applied to the first door body 1 , the engaging member 34 moves in the anti-sliding direction while being in contact with the rear edge 514 of the first groove portion 51 . At this time, a component force G of the force R is applied to the trailing edge 514 .
