Abstract
In a sliding structure in which a shaft member is retained slidably in a guide hole, the lack of an oil film caused by the edge contact of the shaft member to which a pressing load in the axial direction is applied is prevented. With the fact being taken into account that end portionsand, which are always in slidable contact with a side surfaceof a guide hole, of a side surfaceof a shaft memberare the partial edge portion, a plurality of labyrinth groovesandare formed in the end portionsand, respectively, thereby it is possible for an oil film to cover the entire contact portion without increasing the groove width extremely. Because the groove width is not increased extremely, the length of the sliding portions can be ensured.
