  The seat stanchion 31 has a complicatedly bent shape so as to secure a passenger's boarding space and prevent the passenger's movement and the like, and its manufacturing error and mounting error are completely eliminated. difficult. Therefore, if the through hole used for fixing is formed from the beginning, the position of the through hole on the seat stanchion 31 side and the through hole on the bracket side may not match at the time of attachment. Therefore, when the seat stanchion 31 is fixed, in order to absorb these errors, a fixing position of the seat stanchion 31 is temporarily determined, a through hole is formed, and is fixed using a bolt or the like. The work process was complicated.

  There was also a problem in installing the harness 44 for the push button 43. In order to prevent the electrical wiring of the harness 44 and the like from being inadvertently disconnected, it is desirable to install the wiring so as to avoid exposure as much as possible, and in view of the problem of poor contact and cost reduction, an extra connector It is desirable that the connection can be made with a single wiring without using, for example. Therefore, when installing the harness 44 from the ceiling 32 side, the wiring is routed from the ceiling 32 side to the seat stanchion 31 side through the inside of the long handrail 34, or from the ceiling 32 side to the inside of the column 33, Further, it is necessary to perform wiring on the side of the seat stanchion 31 via the inside of the handrail 34, and the work process may be complicated. Moreover, as shown in FIG. 4, there are a plurality of fixing bolts, screws and the like in the portion of the T-shaped bracket 35, and when the harness 44 is installed before the bolts and screws are attached, There is a risk of damaging the harness 44 when drilling through holes or attaching bolts, screws, etc. When installing the harness 44 after installing bolts, screws, etc., use bolts, screws, etc. The cross-sectional areas of the hollow portions of the handrail 34 and the seat stanchion 31 are reduced, and it is difficult to pass the harness 44 through the hollow portions.

Even if the harness 44 is installed after the bolts and screws are attached, the cross-sectional area of the hollow portion of the seat stanchion 31 is reduced by the bolts and screws, and it is difficult to pass the harness 44 through the hollow portion. . Further, even after the seat stanchion 31 is fixed, the harness 44 may be damaged by the tip of the screw or the thread.

  The seat stanchions 31 are used by passengers, and for safety, screws or the like having as few protrusions as possible are used. Specifically, the turnbuckles 66a and 66b are used to fix the seat bracket 42 and the seat stanchion 31, and the cost is high. As shown in FIG. 5C, the turnbuckles 66a and 66b are configured such that the tip of the turnbuckle 66a on the male screw side does not protrude from the head of the turnbuckle 66b on the female screw side. A screw thread is formed inside the shaft portion of the turnbuckle 66b, and the tip portion of the turnbuckle 66a is screwed into this shaft portion.

  Further, the cushion pipe 54 of the seat stanchion 31 is merely disposed so as to contact the upper end portion of the receiving portion 64 of the seat bracket 42, specifically, the upper edge portion of the entrance of the opening 65. In the case of deviation, the internal stanchion pipe 53 is directly exposed, resulting in a problem that the appearance is deteriorated.
