Support structure for gear

Abstract

Disclosed is a support structure for a ring gear (32), which includes: a clutch drum (6) coupled by spline fitting with the ring gear (32); and first and second snap rings (38, 39) mounted to a circumferential wall (62) of the clutch drum (6) and supporting the ring gear (32). The first snap ring (38) is positioned so as not to overlap with the ring gear (32) in a radial direction. The second snap ring (39) is positioned so as to overlap with the ring gear (32) in the radial direction. A length (a1) of the first snap ring (38) in the radial direction is longer than a length (a2) of the second snap ring (39) in the radial direction.

Dependencies are inferred from the claim text.
