A small-diameter screw portion 11 of a stepped screw 12 including a large-diameter flange portion 9, a medium-diameter flange portion 10, and a small-diameter screw portion 11 formed by injection molding of a synthetic resin is screwed into the left screw hole 8. When the small diameter screw portion 11 is screwed, the middle diameter flange portion 10
Is in close contact with the bottom surface 7 and an annular gap is formed between the large-diameter flange 9 and the bottom surface 7. In the gap, the mounting screw cylinder 13 formed by injection molding of a synthetic resin is rotatably pinched.

[0007] The mounting screw cylinder 13 includes an annular portion 14 fitted into the annular gap, a tapered portion 15 rotatably engaged with the tapered recess 6, and a rotary screw portion 16 rotatably engulfed with a spanner. The right screw groove 17 is formed on the inner surface of the rotary screw portion 16. When the mounting screw tube 13 is fitted into the tapered recess 6 and the small-diameter screw portion 11 of the stepped screw 12 is inserted into the center and turned to the left, the intermediate-diameter flange portion 10 comes into close contact with the bottom surface 7 and stops, and the large-diameter flange portion stops. Between the diameter flange 9 and the bottom surface 7,
The mounting screw tube 13 can be fixed.

Reference numeral 18 denotes a fixed pedestal formed by injection molding of synthetic resin or metal, which is fixed to the wall surface 4 with screws 19, has a disk shape, and has a right screw 20 formed on the outer peripheral surface. A projection 21 parallel to the wall surface 4 is formed on the grip bar mounting side 3 of the side bracket main body 1. The outer diameters of the projections 21 are formed to have different diameters, and a desired number of horizontal slits 22 are formed. The protrusion 21 has a diameter smaller than the diameter of the grip bar mounting side 3,
A step 23 is formed. The diameter of the grip bar mounting side 3 is formed to be the same as that of the grip bar 24.

The gripping rod 24 is made of a stainless steel hollow pipe 2.

Next, the deformable projection 27 of the grip bar 24 is engaged with the slit 22 of the projection 21 on the grip bar mounting side 3 side of the side bracket main body 1, and the rotary screw portion 16 is fixed while holding the side bracket main body 1 as it is. It is screwed into the right screw 20 of the pedestal 18.

[0011]

According to the present invention, the wall surface 2 is gradually separated from the wall surface 4 as it goes from the wall surface 2 formed by injection molding of synthetic resin to the grip bar mounting side 3 and has a substantially L-shape. It has a large diameter, becomes smaller in diameter as it reaches the grip bar mounting side 3, curves gently in an arc shape, and has a circular cross section, and the end face 5 of the wall side 2 is parallel to the wall face 4 and the inside of the end face 5 is tapered. A concave portion 6 is formed, a left screw hole 8 is formed at the center of the bottom surface 7 of the tapered concave portion 6, a projection 21 parallel to the wall surface 4 is formed on the gripping rod mounting side 3, and a slit 22 in the generatrix direction is desired for the projection 21. The number of formed protrusions 21 is smaller than the diameter of the gripping bar mounting side 3, and the diameter of the gripping bar mounting side 3 is the same as that of the gripping bar 24.
A large-diameter flange 9, a medium-diameter flange 10, and a small-diameter screw 11 are formed by injection molding of a synthetic resin. A stepped screw 12 in which an annular gap is formed between the large-diameter flange portion 9 and the bottom surface 7 in close contact, an annular portion 14 formed by injection molding of synthetic resin and fitted into the annular gap, and the tapered recess 6, a mounting screw tube 13 formed of a tapered portion 15 rotatably engaged with the rotary screw portion 16 and a rotary screw portion 16 rotatable by a wrench, and a disk-shaped member formed by injection molding of synthetic resin or metal. Since the outer peripheral surface is a side bracket for a gripping bar composed of the fixed pedestal 12 formed with the right screw 20,
The side bracket main body 1 is curved into a substantially L-shape formed by injection molding of a synthetic resin, the wall surface side 2 has a large diameter, and becomes smaller in diameter toward the grip bar mounting side 3, and is curved in a gentle arc shape. However, since the cross section is circular in all parts, it is robust. The end surface 5 of the wall surface side 2 is parallel to the wall surface 4, and a tapered recess 6 is formed inside the end surface 5,
Since the tapered portion 15 is engaged with the tapered portion 15 of the mounting screw tube 13 formed by injection molding of a synthetic resin,
Not only is it easy to manufacture, but the mounting screw cylinder 13 can be engaged without any play. Since the left screw hole 8 is formed at the center of the bottom surface 7 and the stepped screw 12 is engaged with the left screw hole 8, the rotation is opposite to that of the mounting screw cylinder 13 for the right screw, so that the screw is tightened without loosening. The projection 21 has a diameter smaller than the diameter of the gripping rod mounting side 3 and the diameter of the gripping rod mounting side 3 is the same as that of the gripping rod 24. Anyone can easily hold it. The appearance is elegant.
