<P>PROBLEM TO BE SOLVED: To avoid the following trouble: a power transmitting apparatus utilizing screw fastening cannot intercept the power even when a torque limiter operates. <P>SOLUTION: The power transmitting apparatus (10) comprises: rotary portions (1, 2) which rotate by receiving the rotational driving power from a driving source; and a power intercepting member (3) for intercepting the transmission of an excessive torque from the rotary portions to the rotary shaft (4) of a device to be driven by moving toward the device to be driven. The power intercepting member has a screw portion (303), and integrally rotates together with the rotary shaft by being connected by means of a screw. The rotary portions are provided so as to be arranged between the power intercepting member and the rotary shaft. Because the power intercepting member has a straight portion (403), the straight portion prevents the rotary portion from being caught in the portion between the end face (305a) of the power intercepting member on the side of the device to be driven and the rotary shaft, even when the end face has moved. <P>COPYRIGHT: (C)2007,JPO&INPIT |
