固着する。Prior Art When a toothed pulley is fastened to a mating rotating shaft, the toothed pulley is often fixed to prevent rotation. As shown in Fig. 6, for the toothed pulley 1 made of metal, a hole 2 is made in the web portion for this purpose, and a wrench 3 is inserted into the hole to support the toothed pulley so that it does not rotate, and the nut is tightened to rotate the toothed pulley. Sticks to the shaft.

付けられるようにしたものである。Function The present invention has the above-mentioned features, so that when installing the toothed pulley on the rotating shaft, it is supported by attaching a spanner or the like to the protrusion extending from the bushing.
You can stop the rotation. Since the protrusion has a non-circular cross-sectional shape, it is easy to support it so that it does not rotate, and it can be attached without applying any load to the pulley body.
実施例 本考案の実施例を図面を参照して説明する。Example Embodiments of the present invention will be described with reference to the drawings.
第１図、第２図は、金属製のブツシユ４から延
長した突出部５の外周面に平行な二面を形成した

つていない。 1 and 2 show an embodiment in which a protruding portion 5 extending from a metal bushing 4 has two surfaces parallel to the outer peripheral surface thereof. The bush 4 is insert molded into the boss portion of the toothed pulley 1 made of synthetic resin.
When fastening the pulley to the rotating shaft, rotation of the pulley is prevented by supporting the pulley by attaching a tool such as a spanner to the parallel portion. At this time, the force is applied to the engagement portion between the keyway of the bush 4 and the rotating shaft, and no force is applied to the synthetic resin pulley body at all.
別の実施例として第３図に外形が六角形状の突
出部５を示す。上記と同様に六角形状のレンチを
はめることにより回転を防止する。 As another example, FIG. 3 shows a protrusion 5 having a hexagonal outer shape. Rotation is prevented by fitting a hexagonal wrench in the same way as above.
又、第４図に、外周に平な一面を有する突出部
５の一例を示す。第５図に、断面が長円形の突出
部５の一例を示す。 Further, FIG. 4 shows an example of the protrusion 5 having a flat surface on its outer periphery. FIG. 5 shows an example of the protrusion 5 having an oval cross section.
