[Problems to be solved by the device]

 Therefore, since the handrail bar is only mounted inside the left and right holders, it will rotate. For this reason, in a bathroom, toilet, stairs, etc., when a person holding a handrail bar operates to stand, sit, or walk, he / she may rotate and slip or fall and fall. Since most of the elderly and sick people use handrails in particular, it is extremely dangerous to rotate and slip or fall while holding the handrail bar in an unstable state, which may cause personal injury. There is a nature. In addition, in order to prevent the handrail bar from rotating, a handrail with a structure in which both ends are bent at a right angle and each tip is attached to a holder and the holder is fixed to a wall surface is also known. . However, since the handrail has to bend the end portion of the metal pipe material, the bend portion is deformed and the appearance is bad, so that the commercial value is low, and the labor for bending is required, so that the handrail cannot be manufactured at low cost. Therefore, there is a demand for a handrail that does not rotate and that is well-formed and inexpensive to use.

[0004]
