Abstract: A planetary carrier includes first and second support hole parts that support a pinion shaft on which a pinion gear is provided from both sides in an axial direction. The planetary carrier includes a first holding member and a second holding member. The first holding member includes a connection end that extends in an axial direction toward a second holding member and that is connected to and faces the second holding member. The second holding member includes a fragile part formed on an end part in a circumferential direction in a region to which the connection end is connected.

Abstract: An annular first thrust bearing (30) includes a first race (30a) which is in contact with a sun gear (Sb), a second race (30b) which is in contact with a ring gear side member (20a), and a rolling body (30c) disposed therebetween, and the second race has a flange portion protruding radially outward. A second connection member (21) is disposed on a radially outer side of the first thrust bearing (30) to face the second race (30b), and a restricting portion (21a) is disposed at a position facing the first race (30a) or the rolling body (30c) on the rolling element (30c) side of the second race (30b). A distal end of the restricting portion (21a) is located radially inward of a distal end of the flange portion (30d).

Abstract: Provided is a structure with a bearing which is capable of suppressing abrasion of a first member and a first annular member of the bearing in contact with the first member even when relative movement occurs between the first member and the first annular member. The structure with a bearing supplies lubricating oil scraped up from an oil reservoir by an output member (12) to a bearing (20) disposed between a ring gear (Rb) and a transmission case (10). The ring gear (Rb) has a communication groove (30) which allows two spaces adjacent to the bearing (20) to communicate with each other in a portion which is in contact with the first annular member (21) located on an inner circumferential side of the bearing (20).

Abstract: Disclosed is a structure with a thrust bearing which is capable of preventing an erroneous assembling operation. An annular first thrust bearing (30) includes a first race (30a) which is in contact with a sun gear (Sb), a second race (30b) which is in contact with a ring gear side member (20a), and a rolling body (30c) disposed therebetween, and the second race has a flange portion protruding radially outward.

A distal end of the restricting portion (21a) is located radially inward of a distal end of the flange portion (30d).
