To prevent the generation of of such a situation by a malfunction that rotation is transmitted undesirably in the state the transmission of rotation is cut.
This rotation transmission device is provided with an input rotary body 1 rotated around an axis, an output rotary body 2 provided on the same axis as the input rotary body to be rotated around the axis, a torsion coil spring 3 wound around the input rotary body and the output rotary body to transmit rotation from the input rotary body to the output rotary body, a plurality of action members 31 and 32 provided at an interval in a winding direction at a part of the torsion coil spring to be integrally rotated with the input rotary body, and a control means 4 to be applied to the action members to prohibit their rotation when transmission of rotation by the torsion coil spring is disconnected. In cutting the transmission of rotation with the torsion coil spring 3, the rotation of the torsion coil spring 3 is prohibited.
