An angle (an angle formed on the minor angle side) θ formed with a virtual line along the direction is set to 90 degrees or more. The predetermined angle θ is appropriately determined according to the fastening property of the stopper 5, the fitting property of the handrail 10 into the recess 11, the dimension of the wall surface side portion 17 in the circumferential direction of the handrail 10, and the like. It may be an angle. The predetermined angle θ may be 90 degrees to 180 degrees, preferably about 90 degrees to 140 degrees, and more preferably about 90 degrees to 120 degrees.

In the present embodiment, the predetermined angle θ is 90 degrees. That is, the projecting direction of the positioning convex portion 18 is a horizontal direction that is a direction orthogonal to the fastening direction of the stopper 5 that is set to the upward direction as described above. In other words, the positioning projection 18 is provided so as to protrude in the direction orthogonal to the wall surface from the wall surface side portion 17 toward the opposite wall surface side.
Moreover, the dimension in the direction along the circumferential direction of the handrail 10 from the portion where the stopper 5 is fixed on the outer peripheral surface of the handrail 10 to the positioning convex portion 18 (that is, the recess 11) is the positioning property of the handrail 10 or the like. From this point of view, the dimensions may be appropriate. This dimension may be about 1/10 to 1/2 of the outer circumference (circumference) of the handrail 10, preferably about 1/8 to 3/8, more preferably 1/6 to 1 /. It may be about 3, and in the example shown in the figure, an example of about 1/5 is shown.
In addition, the protrusion dimension of the positioning convex part 18 is good also as an appropriate dimension from viewpoints, such as the positioning property of the handrail 10. FIG.
In addition, the handrail bracket 12 may be made of metal from the viewpoint of the attachment strength of the handrail 10, for example, may be formed by casting or the like.

When the handrail 10 having the above configuration is fixed to the handrail bracket 12 using the stopper 5, for example, the following method may be used.
First, the positioning projection 18 of the handrail fixing portion 15 of the handrail bracket 12 is fitted into the recess 11 of the handrail 10, and the handrail 10 is positioned in the circumferential direction with respect to the handrail bracket 12.

It is provided as follows. Therefore, when the positioning protrusion 18 is fitted in the recess 11 of the handrail 10 and the stopper 5 is fastened with the handrail 10 placed on the handrail fixing portion 15, the handrail 10 does not easily float from the handrail fixing portion 15. It is possible to reduce the force for pressing the handrail 10. That is, for example, when the stopper 5 is fixed, it is fitted into the recess 11 of the handrail 10 as compared with the case where the protruding direction of the positioning convex portion and the fixing direction of the stopper are substantially the same direction. The positioning protrusion 18 is difficult to be removed from the recess 11. That is, the positioning convex part 18 becomes a hook-like resistance, and the force for pressing the handrail 10 can be reduced.

  Moreover, in this embodiment, the positioning convex part 18 is provided in the wall surface side site | part 17 of the handrail fixing | fixed part 15 formed so that the outer peripheral surface of the handrail 10 may be followed. Therefore, in a state where the handrail 10 is attached along the wall surface 2, the recess 11 of the handrail 10 opens toward the wall surface 2, and the recess 11 of the handrail 10 can be made inconspicuous. Moreover, since the positioning convex part 18 is provided and the wall surface side part 17 extended so that it may follow the outer peripheral surface of the handrail 10 is also located in the wall surface 2 side, this wall surface side part 17 can be made not conspicuous. . In other words, the position where the positioning convex portion 18 is provided can be effectively separated from the portion through which the stopper 5 is inserted without impairing the appearance. Instead of such an aspect, the positioning convex portion 18 may be provided on the opposite wall surface side portion 16 of the handrail fixing portion 15.

Further, in the present embodiment, an example in which the opening direction of the recess 11 of the handrail 10 is a direction different from the radial direction of the handrail 10 is shown, but a direction along the radial direction of the handrail 10 may be used. In this case, the position where the positioning protrusion 18 is provided and the protruding direction may be appropriately changed.
Further, in the present embodiment, an example in which the fastening direction of the stopper 5 is set to the directly upward direction when viewed in the longitudinal direction of the handrail 10 is shown, but the present invention is not limited to such an embodiment, and the longitudinal direction of the handrail 10 In view of the above, it may be obliquely upward. Further, when the stoppers 5 are fixed at a plurality of locations along the circumferential direction of the handrail 10, when viewed in the longitudinal direction of the handrail 10, the fixing direction of the at least one stopper 5 and the positioning projection 18 It is good also as a structure which cross | intersects a protrusion direction at an angle of 90 degree | times or more. In other words, when the fasteners 5 are secured at a plurality of locations along the circumferential direction of the handrail 10, the fastening direction and the positioning convex portion of any of the fasteners 5 as viewed in the longitudinal direction of the handrail 10. The 18 protruding directions may intersect at an angle of less than 90 degrees.
Further, in the present embodiment, an example in which the handrail bracket 12 is fixed to the wall surface 2 is shown. However, the embodiment is not limited to such an embodiment, and for example, the handrail bracket 12 can be attached to the upper surface of the upper wall of the waist wall. It is good. In this case, the shape of the handrail bracket 12 may be appropriately changed.
