The bolt guide plate 81 guides the mounting position of the mounting bolt 78 to the mounting portion receiving plate 76, and holds the nut 80 arranged on the back surface side of the mounting portion receiving plate 76 so as not to fall off. The mounting bolt 78 is a screw having a shaft portion having a male thread portion and a head portion. The washer 82 is arranged between the head of the mounting bolt 78 and the upper surface of the bolt guide plate 81. The nut 80 is held and arranged between the back surface of the mounting portion receiving plate 76 and the bolt guide plate 81. In the initial work state in FIG. 4, the mounting bolt 78 is in a state of being loosened in advance with respect to the nut 80, and there is a gap between the washer 82 and the mounting portion receiving plate 76 via the bolt guide plate 81. .. The mounting bolt 78 and the nut 80 may be firmly fixed in the initial state of work. In that case, in the step of S20 described later, first, the mounting bolt 78 is loosened with respect to the nut 80.

The right side mounting portion 74 includes a fixing plate portion 84, a presser leaf spring 86, and a spring fixing bolt 88. The fixing plate portion 84 is fixed to each other with the skirt guard 56. One end of the presser leaf spring 86 is a fixed end fixed to the fixed plate portion 84 by the spring fixing bolt 88, and the other end is a free end arranged on the upper surface of the fixed plate portion 84 via the skirt guard 56. The free end portion has a curved shape that jumps upward toward the right side, thereby generating an urging force. In the initial working state, the bottom portion of the presser leaf spring 86 at the free end is pressed against the upper surface of the fixing plate portion 84 by a urging force via the skirt guard 56.

One end of the protective cover 60 is fixed to the inner plate 22 of the balustrade portion 20, and the other end has a shape that is separated from the inner plate 22 and bends to the right on the upper side. In the initial work state, the bent portion at the other end of the protective cover 60 covers the mounting bolt 78 of the left side mounting portion 72.

Returning to FIG. 3, the first step as the mounting work is the fixing jig placement step (S12). The fixing jig is a jig that pulls up the sandwiching jig 110 in a state where the end portion 62 of the protective cover 60 is sandwiched and fixes it to the balustrade portion 20. Here, the handrail side fixing portion 100 is used as the fixing jig.

FIG. 5 is a diagram showing the handrail side fixing portion 100. 5A is a top view, and FIG. 5B is a cross-sectional view taken along the line BB of FIG. 5A. The handrail side fixing portion 100 is composed of a main body portion 102 having an inner surface shape corresponding to the outer shape of the handrail 30 and a protective member 104 arranged on the back side of the main body portion 102. The main body 102 is a member having a shape and a material that is fixed by being fitted along the outer shape of the handrail 30. As the material of the main body 102, a soft resin material that bends with a certain force and returns to its original shape by a repulsive force is used. As such a resin material, a soft polyethylene resin is used. The protective member 104 is provided to protect the handrail 30 from being damaged when the handrail side fixing portion 100 is attached to the handrail 30. As the protective member 104, a sponge having elasticity with a low repulsive force is used. Urethane foam resin is used as the material of the sponge. The above material is an example for explanation, and a resin material having other appropriate properties may be used.

The cross-sectional shape of the main body 102 has a shape that naturally covers the handrail 30 so as to follow the outer shape of the handrail 30. The cross-sectional shape of the handrail 30 is symmetrical, but the cross-sectional shape of the main body 102 is asymmetrical, and the depth DL of the curved portion on the left side is set deeper than the depth DR of the curved portion on the right side. Since the depths DL and DR of the curved portion correspond to the engagement allowance of the main body portion 102 with respect to the handrail 30, the main body portion 102 is deeply engaged with the left side of the handrail 30 and shallowly engaged with the right side. The right side of the main body 102 is an edge extending substantially horizontally, and a hole 106 through which the connecting string 130 is passed is provided.

FIG. 6 is a diagram showing the middle of the process of fitting the handrail side fixing portion 100 into the handrail 30 and arranging it as the fixing jig arranging step (S12). As a procedure for fitting the handrail side fixing portion 100 into the handrail 30, the left side having the depth DL of the curved portion having a large engagement margin is first addressed to the left side surface of the handrail 30, and downward in the direction indicated by the arrow in FIG. Insert it by pushing it to the side. Since the depth DR of the curved portion on the right side is smaller than that of the DL, the right side of the handrail side fixing portion 100 can be easily moved downward by simply pushing with a light force, and the handrail side fixing portion 100 is attached to the handrail 30. A connecting string 130 (see FIG. 8) is passed through a hole 106 provided on the right side of the handrail side fixing portion 100, and is pulled downward by a force F as shown by a two-dot chain line. As a result, the handrail side fixing portion 100 is firmly engaged with the outer shape of the handrail 30 at the deep curved portion on the left side and is fixed to the handrail 30 so as to be difficult to come off.

Returning to FIG. 3, in S14, the pinching jig 110 is used to pinch the end portion 62 of the protective cover 60. Either of the procedures of S12 and S14 may come first. FIG. 7 shows the contents of the process of S14. The pinching jig 110 is a plier having a pinching portion 112 on one end and a pinching operation portion 114 on the other side, and has a locking portion 116 and an unlocking portion 118. The pinching operation portion 114 is provided with a hole portion 120 for passing the connecting string 130.

The operator 8 operates the unlocking portion 118 to open the sandwiching portion 112, and inserts the end portion 62 of the protective cover 60 into the opening facing the sandwiching portion 112. Then, the pinching operation portion 114 is operated to shrink the facing openings of the pinching portion 112, the end portion 62 is firmly sandwiched by the pinching portion 112, the unlocked portion 118 is returned to its original position, and the locking portion 116 is activated. As a result, the end portion 62 of the protective cover 60 is firmly sandwiched by the sandwiching portion 112 and does not come off from the sandwiching portion 112 due to the action of the locking portion 116. It is preferable that the openings facing the sandwiching portions 112 are provided with an appropriate pinching area and appropriate unevenness in order to increase the pinching resistance so that the protective cover 60 can be firmly sandwiched. An example of the pinching width along the traveling direction in an appropriate pinching area is about 30 mm.
