An object holding structure includes: an inner member including an end surface, a first clamping surface located radially outward of the end surface, and hook portions arranged in a circumferential direction at intervals on the end surface; an outer member located radially outward of the inner member, including an end surface and a second clamping surface opposed to the first clamping surface through an object; a key plate contactable to the end surface and the end surface; and a retaining ring held between the key plate and claw portions of the hook portions. The key plate includes a first ring facing the end surface, a second ring provided radially inward of the hook portions, and inner tabs located between the hook portions and linking the first ring and the second ring.

A bearing adjustment assembly includes a worm engaged with a worm gear. The assembly also includes a worm bearing located proximate an end of the worm. The assembly further includes a compensation mechanism engaging the worm bearing, the compensation mechanism being adjustable to bias the worm bearing to maintain or adjust a gear mesh load between the worm gear and the worm.

The invention relates to a securing element (1; 1a) for a bearing device (50) in a housing (20) of a drive device (10), wherein the plate-like securing element (1; 1a) has two side legs (34, 35) and a base leg (36) which connects the side legs (34, 35), wherein, between the base leg (36) and the side legs (34, 35), there is formed a cutout (38) for receiving a shaft (12) which is mounted rotatably in a bearing (15), wherein the two side legs (34, 35) are designed to interact, by means of a first face side (21), with the bearing (15) and, by means of a second face side (23), with a stop surface (33) in the housing (20).

An improved configuration for a bearing housing assembly is disclosed herein in which a ring can be configured to be secured in at least two positions such that the bearing assembly positioned inside of the housing can be retained in either a fixed state or a floating state. The ring can be configured to be secured at least partially within the housing in at least a first configuration and a second configuration, such that: (i) the ring is configured to abut the bearing assembly in the first configuration such that the bearing assembly is axially fixed relative to the housing, and (ii) the ring is configured to be spaced apart from the bearing assembly in the second configuration such that the bearing assembly is axially displaceable within the housing.
