The horizontal rails 12 and 13 of the other handrail body 10 (the second handrail body 11 in the second and fourth connecting bodies 29 and 31) are connected to the connecting bodies 20, 29, 30, and 31 by the horizontal rails. 12 and 13 in the length direction (X direction), it slides toward the other handrail body 11 (one handrail body 10 in the second and fourth connecting bodies 29 and 31), and each handrail body 10, The overlapping portion of 11 becomes larger, and the interval displacement is absorbed.

  On the contrary, as shown in FIG. 11, when an interval displacement is generated in which the interval in the X direction between the adjacent housings 1 and 2 is widened, the insertion is made through the movable side insertion holes 22 of the coupling bodies 20, 29, 30, and 31. The horizontal rails 12 and 13 of one handrail body 10 (the other handrail body 11 in the second and fourth connecting bodies 29 and 31) are connected to the horizontal bars 12 and 29 with respect to the connecting bodies 20, 29, 30, and 31. , 13 in the length direction (X direction), slides in a direction away from the other handrail body 11 (one handrail body 10 in the second and fourth coupling bodies 29, 31), and each handrail body The overlapping portion of 10 and 11 is reduced, and the above-mentioned distance displacement is absorbed.

  Further, as shown in FIG. 12, when a horizontal displacement occurs in which the space between the adjacent housings 1 and 2 moves in the plane reverse direction (Y direction), the handrails 10 and 11 have the shaft portions 35 and 68 as the rotation shafts. One handrail body 10 (rotated in the horizontal direction (Y direction) with respect to the wall surfaces 1A, 2A of the casings 1, 2 and inserted through the movable side insertion holes 22 of the coupling bodies 20, 29, 30, 31 ( In the second and fourth connecting bodies 29 and 31, the lateral rails 12 and 13 of the other handrail 11) are in the length direction of the lateral rails 12 and 13 with respect to the connecting bodies 20, 29, 30 and 31.

  Here, the swinging motion along the longitudinal direction (X direction) of the eighth penetrating portion 57 of the first male screw portion 40 is performed in the longitudinal direction of the eighth penetrating portion 57 (see FIG. 14). Since the distance in the longitudinal direction (X direction) of the twelfth penetrating portion 62 and the thirteenth penetrating portion 63 is formed smaller than the distance in the X direction), the swinging motion of the first bolt 39 is reduced. The swing width is such that the inner peripheral surfaces of the twelfth penetrating portion 62 and the thirteenth penetrating portion 63 of the first plate member 60 through which the first male threaded portion 40 of the first bolt 39 is inserted are those of the twelfth. A movable distance with respect to the fifth fixing means 64 and the sixth fixing means 65 fixed to the second stopper plate 52 in the longitudinal direction (X direction) of the through part 62 and the thirteenth through part 63.
