２の回転部材を介して第３の回転部材に伝達され
る回転力伝達系において前記第１の回転部材を逆
転した場合にその回転力が前記第３の回転部材に
伝達されないようにする逆転防止装置であつて、
前記第１の回転部材と第２の回転部材を同軸上に
回転自在に配設すると共に第１の回転部材と第３
の回転部材をそれらの接続側端面に形成したらせ
ん面を係合させて接続し、その接続部に前記軸上

したことを特徴とする逆転防止装置。 When the first rotating member is rotated, the rotational force is transmitted to the third rotating member via the second rotating member.When the first rotating member is reversed, the rotational force is transmitted to the third rotating member via the second rotating member. A reversal prevention device that prevents the rotation from being transmitted to the third rotating member,
The first rotating member and the second rotating member are arranged coaxially and rotatably, and the first rotating member and the third rotating member are arranged coaxially and rotatably.
The rotating members are connected by engaging spiral surfaces formed on their connection side end faces, and an elastic force of a spring member disposed on the shaft is applied to the connection portion. Prevention device.
