Type and worm type shaft rotation operation devices are available. Among these shaft rotation operation devices, for example, the spring type shaft rotation operation device has a hollow cylindrical fixed drum fixed to the main body, and is rotated by an operation handle from one side in the fixed drum. The rotary shaft is rotatably inserted, the interlocking protrusion is provided at the insertion end of the rotary shaft, and the output shaft for rotating the winding shaft is rotatably inserted into the fixed drum from the other side. Then, an engaging projecting piece facing the interlocking projecting piece is projectingly provided at the insertion end of the output shaft, and one end of the coil spring inserted into the fixed drum is locked to the interlocking projecting piece. The other end of the coil spring is locked to the engaging projection.

However, when the winding shaft is rotated in the winding direction of the vinyl sheet, the rotational force of the rotating shaft is transmitted to the output shaft through the coil spring, so that there is a loss in the transmission of this rotational force. The transmission efficiency is poor, and the coil spring is wound around the rotating shaft to store energy so as to rotate the output shaft. Therefore, the rotating operation of the rotating shaft is heavy and the operability is poor. When the winding shaft is rotated in the direction to rewind the vinyl sheet, the coil spring is squeezed or rewound in the winding direction, so this coil spring is easily broken, and the coil spring is rewound from the output shaft side. When it is released, the coil spring is rewound and pressed against the inner wall of the fixed drum to prevent the rotation of the rotating shaft. Braking action by the rotational force of al is sometimes lacking in insufficient reliability, there is a problem that.

Further, in the ratchet type shaft rotation operating device, there is a risk that the winding shaft will rotate abruptly if the switching operation is mistaken. Further, in the worm type shaft rotation operating device, the frictional resistance increases as the load is applied, and there is a problem that the gear ratio becomes too large to solve this with the gear ratio.

The present invention has been made in view of the above point, and it is possible to reliably transmit the rotational force in the forward and reverse directions of the rotating shaft to the output shaft, and also in the forward and reverse directions from the output shaft side. The rotation force can be locked securely, the transmission loss of the rotation force of the rotation shaft transmitted from the rotation shaft to the output shaft is small, and the transmission efficiency can be improved. The rotation operation of this rotation shaft is light and the operability is excellent, and the rotation transmission It can be used for a long time without breaking the part, does not require switching operation like ratchet type, does not have the problem of gear ratio like worm type, and is therefore easy to handle. It is an object of the present invention to provide a highly safe shaft rotation operation device.
