ボス部までを樹脂で一体に形成し、金属の環状部
材を用いて締結固定するものが知られている。 A structure for fixing a resin transmission mechanism such as a gear or a cam to a rotating shaft is disclosed in Japanese Utility Model Application Publication No. 1986-86257,
As stated in Utility Model Publication No. 48-252,
It is known that up to the boss portion is integrally formed of resin and fastened and fixed using a metal annular member.
しかしながら、単に金属の環状部材をボス部に
挿入するだけの構成では、締結のためのボス部と
金属の環状部材の合せ作業が必要となる。特に両
者の嵌合状態がきついと合せ作業が困難であり、
ゆるい嵌合の場合脱落の恐れがあり、製作性、作
業性の面で問題を有している。 However, in a configuration in which the metal annular member is simply inserted into the boss, it is necessary to fit the boss and the metal annular member together for fastening. In particular, if the two are tightly fitted, it is difficult to fit them together.
If the fitting is loose, there is a risk of it falling off, which poses problems in terms of manufacturability and workability.
本考案の目的は、上記した従来の欠点をなく
し、製作性、作業性に優れた回転伝達装置を提供
するにある。 An object of the present invention is to eliminate the above-mentioned conventional drawbacks and provide a rotation transmission device with excellent manufacturability and workability.

る金属の環状部材とより構成したものである。 In order to achieve the above object, the present invention includes a cylindrical resin boss fixed to a rotating shaft with a set screw, a resin transmission mechanism integrally formed on one side of the boss, and a resin transmission mechanism part integrally formed on one side of the boss. a recess formed on the outer surface of the boss, a slit formed along the axial direction of the boss and through which the set screw passes, a protrusion formed on the outer surface of the other side of the boss, the set screw and the recess. The boss includes a metal annular member having a convex portion that fits into the boss portion and is inserted outside the boss portion.
以下、本考案の一実施例を図面に基づいて説明
する。 Hereinafter, one embodiment of the present invention will be described based on the drawings.

の突起８を乗り越えて挿入する際、ばね性を有し
挿入し易くなる。 In FIGS. 1 to 3, the resin member consisting of the transmission mechanism section 2 and the boss section 4 is integrally molded with resin. The cylindrical boss part 4 has two slits 6 spaced about 90 degrees apart along the axial direction, a protrusion 8 on the outer peripheral surface opposite to the transmission mechanism part 2 for preventing slipping off, and a projection 8 on the outer surface that rotates along the axial direction. A recess 10 for stopping is formed. Since the slit 6 is formed in the boss portion 4, when the metal annular member 12 is inserted into the boss portion 4 over the retaining protrusion 8, it has spring properties and can be easily inserted.

The concave portion 10 of the boss portion 4 and the convex portion of the annular member 12 are as follows:
It serves the function of preventing both from rotating, and also serves to position them. Therefore, if the annular member 12 is inserted into the boss portion 4, the slit 6 and the female thread portion 16
match, and can be easily fastened with the setscrew 20. The annular member 12 is provided with a chamfered portion 22,
The outer diameter end of the boss portion 4 and the inner diameter end of the annular member 12 are configured to be easily inserted.
