For this reason, as shown in this figure, a support 93 for attaching such a handrail T to a wall surface is provided with a mounting bolt that penetrates the wall material 91 at a position where the column 92 is disposed on the back side of the wall material 91. By such means, it is attached to the pillar 92, and high attachment strength is secured. Such a pillar 92 is usually
At regular intervals L, in the case of ordinary houses, they are arranged at intervals of about 90 cm.

[0004] On the other hand, as shown in this figure, in a corner portion such as a corridor or a staircase sandwiched between two orthogonal wall surfaces,
The handrail T is connected by an arc-shaped joint 94 or the like. However, in such a corner portion where the handrail T is bent, the handrail T is easily bent, and therefore particularly high mounting strength is required.

However, in the vicinity of such a corner portion, the pillar 92 is usually arranged on the back side of the corner, and no pillar is arranged on the back side of the wall on both sides.

For this reason, in order to secure the mounting strength of the handrail T at the corner portion, conventionally, the wall material 91 is provided near the arc-shaped joint 94 (within 100 mm from the joint 94).
By providing a reinforcing member 95 on the back side of the base member and attaching a mounting member 93 to the reinforcing member 95, the handrail T at the corner portion is supported.

[0007]

However, the means for attaching the handrail T to such a corner portion requires a step of providing a reinforcing member 95 on the back side of the wall material 91.
