  However, the arm shaft portion 23, which is composed of the three rotating disks of the arm base 23a, the spacer disk 23b, and the end plate 23c as described above and forms a rotating disk body, has a fixing screw 4 for the purpose of improving workability. Since it is built in the rotating disk body (see FIG. 3), if the fixing screw 4 is tightened at the halfway end, the fixing screw 4 is sandwiched between the rotating disk and locked as the armrest 2 rotates. This hinders the rotation of the armrest 2 and may cause damage in some cases.

  Therefore, in view of the circumstances as described above, the present invention provides an arm shaft that is constituted by three rotating disks, that is, an arm base 23a, a spacer disk 23b, and an end plate 23c to form a rotating disk body in which a fixing screw 4 is built. Even when the fixing screw 4 is insufficiently tightened in the portion 23, the fixing screw 4 does not interfere with the rotation of the rotating disk body, and it is possible to effectively prevent the occurrence of rotation trouble or breakage. It aims at providing the toilet with an armrest and the armrest for toilets used for it.

  The present invention solves the above-mentioned problems. First, an armrest having an arm shaft portion composed of an arm base, a spacer disk, and an end plate rotates to a toilet body via a base plate as a mounting bracket. An armrest with armrests, where the arm shaft and the base plate are fixed by a fixing screw built into the arm shaft when freely mounted, and the fixing screw located in the end plate of the arm shaft The spacer disk is provided with a relief groove that enters when the head is loosened.

  Secondly, it has an arm shaft portion that is composed of an arm base, a spacer disk, and an end plate and has a built-in fixing screw. The fixing screw is fixed to a base plate as a mounting bracket and is rotatably attached to the toilet body. The spacer disk is provided with an escape groove which is an armrest for a toilet and enters when the screw head of the fixing screw located in the end plate of the arm shaft portion is loosened.

  According to the first and second inventions described above, the fixing screw is insufficiently tightened by providing a clearance groove for the screw head of the fixing screw in the middle spacer disk among the three rotating disks. In the event of a failure, the screw head of the fixing screw enters the escape groove, so that it does not interfere with the rotation of the rotating disk body and can effectively prevent the occurrence of rotation troubles and breakage. Become.

  The spacer disk fixing hole is provided with a relief groove. Normally, the screw head of the fixing screw after tightening is provided on the end plate on the back side of the arm shaft, that is, on the side facing the fixing base plate. It is located in the fixing hole, and if it is loosened, it will be sandwiched between the end plate and the spacer disk in front of it, so it is effective to install it on the spacer disk that is in the position facing when the screw head is loosened. Because there is.

  FIG. 1 shows one embodiment of the present invention as described above, and the screw of the fixing screw 4 is inserted into the fixing hole 233b of the spacer disk 23b among the three rotating disks constituting the arm shaft portion 23. FIG. An escape groove 234b is provided that can escape when the head 41 is loosened.

  More specifically, the escape groove 234b is formed in a groove shape larger than the screw head 41 of the fixing screw 4 at the end of the fixing hole 233b on the end plate 23c side.

  Due to the presence of the relief groove 234b, the screw head 41 of the fixing screw 4 positioned in the fixing hole 233c of the end plate 23c is not sufficiently tightened during construction or loosened due to the rotation of the armrest 2 several times. Even if it comes out slightly from the fixing hole 233c, it enters into the space secured by the escape groove 234b, so that smooth rotation is maintained without being sandwiched between the end plate 23c and the spacer disk 23b. Will be. Thereby, damage to arm axis part 23, base plate 3, etc. can be prevented effectively, and a toilet bowl with armrest 2 still better is realized.
