Abstract: <P>PROBLEM TO BE SOLVED: To provide a shaft connection part structure that highly accurately transmits rotation.  <P>SOLUTION: A rotation transmission shaft 3 is fitted into a shaft hole 4 of a gear 1 as a member to be connected. Both axial ends of a drive pin 7, fitted into a pin engaging hole 20 of the rotation transmission shaft 3 while having a clearance therebetween, are engaged into pin engaging recesses 8 of the gear 1. Therefore, the gear 1 and the rotation transmission shaft 3 are integrally rotatably connected to each other by the drive pin 7. The pin engaging hole 20 of the rotation transmission shaft 3 is formed with a pressure-receiving face 22 in face contact with the drive pin 7 when the gear 1 is relatively rotated at a prescribed angle in one direction with respect to the rotation transmission shaft 3. The drive pin 7 is brought into face contact with the pressure-receiving face 22 formed in the pin engaging hole 20 of the rotation transmission shaft 3 when rotation is transmitted. Therefore, it prevents the occurrence of stress concentration at the contact part between the drive pin 7 and the rotation transmission shaft 3 while suppressing elastic and plastic deformation of the pin engaging hole 20. Consequently, it allows rotation to be highly accurately transmitted.  <P>COPYRIGHT: (C)2011,JPO&INPIT
