本発明はシャフト上の軸受を軸方向に固定する軸受固定
装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bearing fixing device for fixing a bearing on a shaft in the axial direction.
この種軸受固定装置は従来スナップリングと称せられる
リングで構成し、とれをシャフトの円周条溝に係着して
該シャフト上の軸受を軸方向に固定するのが普通である
。This type of bearing fixing device is conventionally constructed with a ring called a snap ring, and the snap ring is usually engaged with a circumferential groove of a shaft to fix the bearing on the shaft in the axial direction.

の操舵輪を所定通り転舵可能である。An example of its application will be explained in the case of a rack-and-pinion type steering gear shown in Fig. 1. In Fig. 1, 1 is a gear hawing, 2 is a pinion shaft, 8 is a pinion formed on the pinion shaft 2, and 4 is meshed with the pinion 8. The rack 5 is a retainer, 6 is a spring, 7 is an adjuster, and 8 is a lock nut. meshes with each other to provide preload. The pinion shaft 2 is rotatably supported with respect to the housing l by a bushing 9 at one end and a bearing 10 near the other end, and when the pinion 8 is rotated via the pinion shaft 2 by steering operation of the steering wheel, the rack 4 can move in the corresponding axial direction to turn the steering wheels of the vehicle in a predetermined manner.

。The bearing 10 has its outer race axially fixed in the housing 1 by a snap ring 1 which is engaged within the housing 1, and the inner race is fixed to the pinion shaft 2 by a snap ring 12 and 18 which is engaged with the pinion shaft 2. It is fixed in the axial direction, and as a result, the binion shaft 2 can be fixed in the axial direction with respect to the housing l.

ついて図示する)をあまり大きくすることができない。By the way, in the conventional bearing fixing device for fixing the bearing 1o on the pinion shaft 2 in the axial direction, the outer circumferential groove 2a of the pinion shaft 2 is enlarged and clearly shown in FIG.
, 2b, and in order to sandwich the bearing 10 between these snap rings, both snap rings 12 and 18 are engaged with the outer circumferential grooves 2a and 2b so that they are radially outward. It is necessary to extend the elastically expanded state to the corresponding outer circumferential grooves 2a and 2b in the axial direction.Therefore, the snap rings 12 and 18 have a plate thickness t (snap (only the snap ring 12 is shown) and the width W (only the snap ring 12 is shown) cannot be made too large.

It is necessary to reduce the diameter of the bottom wall of the outer circumferential groove 2a in order to keep the run-off allowance B as specified, but in this case, the run-off allowance d with the bearing 10 decreases, which also makes the bearing more susceptible to damage. The lO may even come off in the axial direction, resulting in a lack of bearing fixing ability.

係合し合う鉤状部を設は之ことを特徴とする。The present invention provides a bearing fixing ring that can be attached to the outer circumferential groove of the shaft without expanding in the radial direction like a snap ring, so that the plate thickness and width of the ring can be sufficiently reduced without the above-mentioned restrictions. The bearing fixing device of the present invention is a concrete embodiment of this idea from the viewpoint that it can be made larger and can solve all the problems mentioned above. A hook-shaped portion is provided in each of the sections to engage with each other so that when the two ring divided portions are moved relative to each other in the axial direction and aligned in a plane perpendicular to the axis, the two ring divided portions cannot be separated in the radial direction. It is characterized by this.
