PLANETARY BEARING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a planetary bearing structure that can prevent a planetary gear and a sliding bearing from relatively moving and rotating.SOLUTION: A planetary bearing structure includes: an opening 26a formed around an axis; a planetary gear 26 having a first groove 26b formed in an axial direction in an inner circumferential surface of the opening 26a; a sliding bearing 24 having a second groove 36a formed in an axial direction in an outer circumferential surface, having the outer circumferential surface contacting with the inner circumferential surface of the opening 26a of the planetary gear 26 and installed within the opening 26a of the planetary gear 26; and a pin 41 inserted into a hole formed by aligning the first groove 26b and the second groove 36a.
