PURPOSE:To transmit rotation surely from a rotational member to a member to be rotated even if the member to be rotated is such as a drum shaft CONSTITUTION:A rotation transmission device is provided with a rotational member 14 which is given a torque from a driving source, a member to be rotated 1 which is going to transmit rotation of the rotational member 14 and a rolling member 50 which is arranged between inside of the rotational member 14 and the outside of the member to be rotated 1, and is so constituted that only one-way rotation of the rotational member can be transfered to the member to be rotated via the rolling member. And an intervening member 22 is set between the rolling member and the member to be rotated, and the intervening member has grooves 40 formed in the direction different from shaft direction of the intervening member. |
