A sliding shaft connected to one of the two rotating shafts so as to be integrally rotatable and slidable in the axial direction and facing the other rotating shaft, and a sliding shaft that is opposite to the other rotating shaft and rotates the other rotating shaft a positive rotation transmitting means formed between the shaft and the shaft and transmitting positive rotation only when abutting with a friction force of a certain level or more; and a rotation transmitting section provided on the outer periphery of the other rotating shaft and the sliding shaft, respectively. , which is rotatably provided intersecting the axes with respect to the other rotating shaft and the sliding shaft and slidably in the axial direction, and is always engaged with the rotation transmitting portion of the other rotating shaft;
The forward rotation transmitting means engages with the rotation transmitting portion of the sliding shaft only at the separated position and rotates together with the reverse rotation transmitting member that transmits the rotation in the opposite direction. and a cam mechanism that applies axial displacement to the sliding shaft to switch between forward rotation transmission and reverse rotation transmission, and inputs continuous rotation in the positional direction to one rotating shaft and transfers the rotation to the other rotating shaft. A forward/reverse rotation switching device characterized by alternately outputting forward rotation and reverse rotation. (2) An elastic body that always biases the sliding shaft toward the other rotating shaft, and an elastic body that always biases the reverse rotation transmission member toward the other rotating shaft and the sliding shaft. , engaging surfaces of the positive rotation transmission means of the other rotating shaft and the sliding shaft that engage with the other rotating shaft, and the rotation transmitting portion of the other rotating shaft and the rotation transmitting portion of the sliding shaft that engage with these. 2. The forward/reverse rotation switching mechanism according to claim 1, wherein each engagement surface of said reverse rotation transmission member is formed into a slope-like unevenness.
