PURPOSE:To make a connecting mechanism simple for making engagement and disengagement between rotary shafts easy, and further, to transmit rotational power stably, by engaging the rotary shafts with each other at their end portions through groove portions and a pin member. CONSTITUTION:The end portion of a rotary shaft 32 is inserted into the hole portion 38 of a rotary shaft 34 and both ends of a pin member 36 are fitted in grooves 40a, 40b for completing the connection between those rotary shafts. And rotation of the rotary shaft 34 transmits driving power to the rotary shaft 32 through the pin member 36 so as to rotate the rotary shaft 32. In this case, even though any shift and/or vibration of a rotary shaft may take place, no used of any tostening member such as a bolt, etc., can avoid the slippage of the connecting portion of a rotary shaft and the generation of the frictional heat for preventing wear. Thereby, the simplification of the connecting mechanism is attempted and is facilitated engagement/disengagement of the rotary shaft is facilitated and further, rotational power can be transmitted stably. |
