オロワをカム溝に係合させると同時に、上記一対
のベベルギヤのバツクラツシによる相対回転を阻

係合させることを特徴とするベベルギヤのバツク
ラツシ除去装置。 A pair of bevel gears that mesh with each other and transmit power intermittently, a cam member that rotates integrally with one bevel gear, and a cam member that rotates integrally with the other bevel gear, and a part of the movement locus corresponds to the movement of the cam member. a cam follower that overlaps the locus, the cam member is provided with a cam groove that allows the cam follower to pass along the locus of movement of the cam follower, and the cam follower is engaged with the cam groove at a rotation stop position of the bevel gear. At the same time, the cam groove is closely engaged with the cam follower so as to prevent the pair of bevel gears from rotating relative to each other due to backlash.
