    • A bearing device for a wheel, in which circumferential play is minimized and in which a hub ring and an outer joint member of a constant velocity universal joint can be connected with excellent workability. Axially extending projections (35) are formed on either one of the outer diameter surface of a shaft (12) of the outer joint member and the inner diameter surface (37) of a hole (11) of the hub ring (1), and the projections (35) are axially press fitted into the other. Recesses (36) fitted in an intimate contact manner onto the projections (35) are formed in the other. Thus, a recess/projection fitting structure (M) is formed. In the structure (M), the entire fitting/contact portions (38) of the projections (35) and the recesses (36) are in intimate contact with each other. Further, a shaft come-out prevention structure (M1) is provided between the shaft (12) of the outer joint member and the inner diameter surface of the hub ring (1).
    • 一种用于车轮的轴承装置,其中周向游隙最小化,其中轮毂环和等速万向接头的外接头构件可以以优异的可加工性连接。 轴向延伸突起(35)形成在外接头构件的轴(12)的外径表面和轮毂环(1)的孔(11)的内径表面(37)中的任一个上, 突起(35)轴向压配合到另一个中。 在另一方面形成有以紧密接触的方式安装在突起(35)上的凹部(36)。 因此,形成凹凸配合结构(M)。 在结构(M)中,突起(35)和凹部(36)的整个嵌合/接触部分(38)彼此紧密接触。 此外,在外接头构件的轴(12)和轮毂环(1)的内径表面之间设置有轴防止结构(M1)。
