Unlike the case where the tip end surface of the impact absorber 3a is not inclined, when the projecting and collapsing body 32a of the shock absorbing device 3a abuts the facing end part 6b, the tip surface of the projecting and collapsing body 32a and the contact surface of the end part 6b. Since they are parallel to each other, the shock absorbing device 3a can be operated more smoothly.

Next, a fourth embodiment will be described. In the fourth embodiment, as shown in FIG. 7D, the shock absorption is performed so that the angle formed between the tip surface of the projecting and retracting body 32a of the shock absorbing device 3a and the projected surface of the contacting end part 6b becomes small. The attachment angle of the device 3a is inclined such that the projecting and retracting body 32a side is closer to the rear side with respect to the finding direction of the shoji 1a, and the advancing and retracting direction of the projecting and retracting body 32a is also slanted. When the shoji 1a and 1b are closed, the projecting and retracting body 32a abuts on the prospective surface of the opposing end part 6b and is pushed into the accommodating portion 64a while absorbing the shock at the time of closing. , Is completely immersed in the accommodating portion 64a.

According to the fourth embodiment, in addition to the same effects as the first embodiment, the impact absorbing device 3a as shown in FIG. 7(a) is not inclined when both the shoji 1a and 1b are closed. Compared with the case, when the projecting and collapsing body 32a of the shock absorbing device 3a comes into contact with the opposing end part 6b, the tip surface of the projecting and collapsing body 32a and the contact surface of the end part 6b become close to parallel. The shock absorbing device 3a can be operated more smoothly.

Alternatively, the shock absorbing device may be directly attached to the frame without the end parts. In that case, the impact absorbing device does not necessarily have to be vertically symmetrical as long as it is provided above the one shoji screen and below the other shoji screen. Since the shape of the impact absorbing device mounting side can be made the same, both vertical frames can be made common and the manufacturing cost can be suppressed. Then, in the case where the end part is not provided, a recess as in the second embodiment may be provided on the prospective surface of the shoji facing the impact absorbing device. Further, as in the third embodiment and the fourth embodiment, when the tip end surface of the shock absorbing device or the shock absorbing device itself is inclined, a recess may be provided on the facing contact surface.
