摘要： PURPOSE: To mechanically prevent the partial contact of a bearing by making the internal peripheral surface of a bearing member be a slide bearing face, fitting the bearing member to a housing with a minute gap, and tilting the bearing member in a given range in this minute gap following the inclination of a crank shaft in operation. CONSTITUTION: A main bearing section has a man bearing member 31a, the internal peripheral surface of which is made to be a slide bearing face by providing a bearing bushing 31c, for example, inside a bearing holding member 31b, forming a cylindrical body, in the outside of which a projected line 31d is formed extending in the peripheral direction. In the bearing bushing 31c, a thrust bearing section 34 is uniformly formed. The main bearing member 31a can be assembled by being inserted into the housing 3e provided in a main frame 3 from an upper section and is fittedly held with a minute gap so as to be tilted in a given range, and the self-weight of the main bearing member 31a is supported on a receiving face 3f. In order to prevent the rotation of the main bearing member 31a, the housing 3e is provided with a detent 3g.
