Regarding the sliding bearing used.

問題があつた。[Prior Art] Such a conventional sliding bearing is shown in FIG. 3, in which a sleeve 2 fitted to a shaft 1 and a bearing 4 provided in a bearing case 3 are made of ceramic as sliding members. Alternatively, it is made of a hard and brittle material such as cemented carbide. In such sliding bearings, when there is misalignment between bearing 4 and shaft 1, bending of shaft 1 due to external force during operation, etc., so-called "run-in" does not occur as with white metal bearings or rubber bearings. First, as shown in FIG. 3, there is a problem in that the shaft 1 makes partial contact with the bearing 4, and a high surface pressure is locally applied to the portion where the partial contact occurs.

受との片当りが生じないようになつている。 In order to deal with such problems, a sliding bearing having a structure as shown in FIG. 4 or 5 has been proposed. In the bearing shown in FIG. 4, the sleeve 2 and the bearing 4 are attached to a metal sleeve 7 and a metal shell 8, respectively, and the shaft 1
Elastic materials 10 and 11, such as rubber, are interposed as cushioning materials between the bearing support member 9 and the metal sleeve 7 and between the bearing support member 9 and the metal shell 8, respectively. By elastically deforming the elastic members 10 and 11, even if misalignment or bending of the shaft occurs, uneven contact between the shaft and the bearing does not occur.

題がある。[Problems to be Solved by the Invention] However, in the prior art shown in FIG. 4, the elastic modulus of the elastic materials 10 and 11 such as rubber is relatively large;
The amount of deformation per unit load is small. Therefore, in order to sufficiently deform the elastic members 10 and 11 in response to misalignment and bending, it is necessary to increase the amount of deformation by increasing (thickening) the radial dimension (thickness). Therefore, there is a problem in that the radial dimension of the entire bearing becomes large, which goes against the demand for reduction in size and weight.

Furthermore, there is a problem in that extra space is required in the radial direction due to the provision of the alignment mechanism.

Moreover, since it is not supported in the axial direction by a buffer material, there is a problem in that it cannot sufficiently absorb or attenuate external forces and vibrations applied in the axial direction.

The microfilm photographing the contents of the specification and drawings attached to the application No. 93462 (Utility Model Application No. 62-204015) uses a hard brittle material as the sliding member, and includes the bearing case and the bearing-side sliding member. A sliding bearing with a buffer member provided between the two is shown. but,
In this technique, since an elastic material such as rubber is used as a buffer member, a problem similar to that of the embodiment shown in FIG. 4 exists. In other words, since the amount of deformation per unit load is small, in order to deform the elastic material sufficiently, it is necessary to increase the radial dimension and increase the amount of deformation, which increases the size of the entire bearing.
There is a problem in that it goes against the demand for smaller size and lighter weight.

The microfilm photographing the contents of the specification and drawings attached to the application in No. 2004-12-12 shows a technique in which a through hole is formed in the shock absorbing member of a bearing in the axial direction thereof.

くすることができる。[Function] According to the sliding bearing of the present invention having the above-described configuration, since the through-hole is formed in the buffer member in the axial direction, the elastic modulus of the entire buffer member is reduced, and the elastic modulus of the entire buffer member is reduced. The amount of deformation also increases. Therefore, by appropriately setting the position or number of through holes, it is extremely easy to adjust the elastic modulus and the amount of deformation to optimal values. In addition, the radial dimension of the buffer member required to obtain enough deformation to cope with misalignment and bending of the shaft can be reduced.
The entire sliding bearing becomes smaller. In addition, since the sliding bearing of the present invention does not require any special alignment mechanism, the radial dimension can be made smaller.

も摺動面に局所的な高面圧が生ずることがない。 In addition, by housing the bearing-side sliding member in the recess of the buffer member, external forces and vibrations applied not only in the radial direction but also in the axial direction can be sufficiently absorbed by the buffer member.
It is damped, and even if the shaft is tilted due to misalignment or bending, local high surface pressure will not occur on the sliding surface.

向について変位してしまうことが無い。 Furthermore, a recess is formed in the inner circumferential surface of the buffer member, and the bearing-side sliding member is fitted into the recess in such a manner that both axial ends of the bearing-side sliding member are covered with the buffer member to be integrally fixed. However, since the outer circumferential surface of the buffer member is integrally fixed to the inner circumferential surface of the bearing case, the buffer member will not be displaced in the axial direction even if an external force acting in the axial direction is applied.

This prevents uneven contact between the bearing 26 and the bearing 26, and also has a damping effect against axial vibration. Further, during assembly, there is no risk that the sleeve 24 or bearing 26 made of hard brittle material will be damaged when the shaft 22 is inserted.
