<P>PROBLEM TO BE SOLVED: To provide a power transmission improved in reliability and durability by preventing occurrence of welding, abrasion, rust, etc. on a contact part between members constituting a connecting part. <P>SOLUTION: This power transmission constitutes the connecting part by combining separate members of the positive torque transmitting member to transmit torque in a positive rotating direction and to shut out transmission of torque from a driving body by rupture of itself when a driving load of a driven body exceeds prescribed value and the negative torque transmitting part free to transmit torque in a reverse rotating direction by devising it to shut off transmission of the torque from the driving body when the driving load of the driven body exceeds the prescribed value by connecting the driven body rotated in the same direction and the driving body driving the driven body through the connecting part. This power transmission also interposes a surface layer dissimilar to a material constituting the positive transmitting member and the negative transmitting member on the contact part between the positive torque transmitting member and the negative transmitting member. <P>COPYRIGHT: (C)2009,JPO&INPIT |
