Will be easier.

Further, since the base-side fitting portion 11 and the bracket-side fitting portion 12 are fitted to each other like a wedge, there is no play of the bracket body 3 with respect to the base 2, and as a result, the bracket body with respect to the base 2. It is possible to prevent the handrail 3 from rattling and the handrail 1 from becoming unstable.

Further, according to the handrail bracket 10 according to the embodiment of the present invention, one bracket side fitting portion 12a is formed by utilizing the cavity 13 for reducing the weight provided in the bracket body 3. Further, the base-side fitting portion 11a has a shape corresponding to the shape of the one bracket-side fitting portion 12a.
However, since it is formed in the approximately central portion of the base 2, a large fitting portion can be provided by effectively utilizing the space of the cavity 13, and as a result, the bracket body 3 can be more firmly assembled to the base 2. You can

Further, according to the handrail bracket 10 according to the embodiment of the present invention, the other base side fitting portion 11b surrounds the opening portion of the bracket body fixing screw hole 8b which is screwed into the bracket body fixing screw 8. Therefore, not only can the fitting portion be provided by effectively utilizing the space around the bracket body fixing screw hole 8b, but also the screwing portion of the bracket body fixing screw hole 8b can be lengthened. As a result, the bracket body 3 can be more firmly assembled to the base 2.

Further, according to the handrail bracket 10 according to the embodiment of the present invention, the bracket main body 3 has the base fixing screw insertion hole 7c through which the base fixing screw 7 is inserted so as to face the base fixing screw receiving seat 7a. Since the base 2 and the bracket are fixed by the bracket body fixing screw 8, the handrail bracket 10 can be fixed to the building material part by inserting the base fixing screw 7 through the base fixing screw insertion hole 7c.

Further, once the handrail bracket 10 has been fixed to the building material portion, the bracket body fixing screw 8 can be loosened to remove the bracket body 3 from the base 2 without removing the base 2 from the building material portion. As a result of eliminating the need to remove the base fixing screw 7 when exchanging the bracket 10, the screw hole becomes larger or another screw hole is opened due to the removal of the base fixing screw 7, and the base of the building material part is damaged. Never be Therefore, it is possible to prevent the handrail bracket 10 from rattling and the handrail 1 from becoming unstable.

Further, according to the handrail bracket 10 according to the embodiment of the present invention, the positioning member 5 fixed to the building material portion and the positioning groove portion 6 provided on the building material portion side of the base 2 are provided.
Since the handrail bracket 10 is positioned with respect to the building material portion by fitting and, for example, by providing the positioning member 5 in the building material portion before attaching the interior material such as a cloth to the building material portion. The base 2 can be easily positioned with respect to the building material portion even when the building material portion is covered with the interior material and the mounting position of the base becomes unclear.

Further, according to the handrail bracket 10 according to the embodiment of the present invention, the positioning member 5 can be easily fixed to the building material portion by the pin portion 5a of the positioning member 5.
