  The one side main body 16 and the one side moving body 17 may be connected by a hinge. The other side body and the other side moving body may be connected by a hinge. Also in this case, if a fastening body is used, a working scaffold device can be installed.

Second Embodiment
FIG. 7 is a view on arrow of the main part of the work scaffolding device for an escalator according to Embodiment 2 of the present invention. FIGS. 8-10 is a perspective view of the principal part of the working scaffold apparatus of the escalator in Embodiment 2 of this invention. The same reference numerals as in the first embodiment denote the same or corresponding parts. The description of the relevant part is omitted.

  As FIG. 7 shows, the 1st 1st holding body 14 of Embodiment 2 is the 1st 1st fastening body 18, the 2nd 1st fastening body 19, the 1st 1st buffer 20a, and the 2nd one side. The buffer 20b and the third one-side buffer 20c are not provided. The first one-side gripper 14 of the second embodiment includes a fourth one-side buffer 20 d.

  For example, the fourth one-side buffer 20 d is formed of rubber. The fourth one-side buffer 20 d entirely covers one of the pair of handrails 7.

  The one side main body 16 grips one of the pair of handrails 7 via the fourth buffer 20 from one of the inner side and the outer side in the width direction of the escalator.

  The one-side movable body 17 is not displaced from one side of the pair of handrails 7 by a distance set in advance with respect to the one-side main body 16 from the other side of the widthwise inside and outside of the escalator. Hold one of the

  Although not shown, the second one-side gripper 15 of the second embodiment includes one side main body equivalent to the one-side main body 16 of the first one-side gripper 14 of the second embodiment. The second one-side grip 15 of the second embodiment includes one-side movable body equivalent to the one-side movable body 17 of the first one-side grip 14 of the second embodiment. The second one-side grip 15 of the second embodiment includes a fourth one-side shock absorber equivalent to the fourth one-side shock absorber 20 d of the first one-side grip 14 of the second embodiment.

  The other-side gripper 11 of the second embodiment includes a first other-side gripper equivalent to the first one-side gripper 14 of the one-side gripper 10 of the second embodiment. The other-side gripper 11 of the second embodiment includes a second other-side gripper equivalent to the second one-side gripper 15 of the one-side gripper 10 of the second embodiment.

  As shown in FIGS. 8 and 9, the one side main body 16 and the one side moving body 17 form an internal space. The internal space is formed in a bowl shape. For example, the width of the internal space narrows from the near side to the far side in FIG.

  As shown in FIG. 10, the outer shape of the fourth one-side buffer 20d is formed in a bowl shape. For example, the width of the fourth one-side buffer 20d narrows from the near side to the far side in FIG.

  According to the second embodiment described above, the first one-side gripping body 14 and the second one-side gripping body 15 grip one of the pair of handrails 7 without using a fastening body. The first other-side grasper and the second other-side grasper grasp the other of the pair of handrails 7 without using a fastening body. For this reason, the working scaffold device can be installed with a simpler configuration.

  In addition, an internal space formed between the one side main body 16 and the one side moving body 17 is formed in a bowl shape. The outer shape of the fourth one-side buffer 20d is formed in a bowl shape. For this reason, the one side grip body 10 can be more firmly fixed to one of the pair of handrails 7.

  Although not shown, the internal space formed on the other side main body and the other side moving body is also formed like a bowl. The outer shape of the fourth other-side cushioning body corresponding to the other-side main body and the other-side moving body is also formed in a bowl shape. For this reason, the other side gripping body 11 can be fixed more firmly to the other of the pair of handrails 7.
