In a raceway member (an outer ring member) for a wheel bearing device, a seal is mounted on an axial end section of the outer ring member with respect to a rolling body so as to suppress non-uniformity in the interference that a lip of the seal has on the seal surface. This assembly device (40) is a device for mounting an annular seal (15) to an axial end section (17) of an outer ring member (12)for a wheel bearing device by means of press-fitting. The assembly device (40) is provided with: a columnar guide member (41) having a contact surface (44) which is continuous in the circumferential direction and which, from the opposite side as an outer raceway surface (12a) formed on the outer ring member (12), is brought into contact with a plurality of balls (13) provided along the outer raceway surface (12a); a pressing member (42) which axially moves along a guide member (41) toward the axial end section (17) to axially push and press-fit the seal (15) into the axial end section (17); and a reference member (43) for restricting an axial movement stroke of the pressing member (42) with respect to the guide member (41).
在车轮用轴承装置用的滚道构件(外圈构件)中,为了抑制密封件具有的唇部相对于密封面的过盈量的偏差,以滚动体为基准,将密封件安装到外圈构件的轴向的端部。组装装置(40)是用于将环状的密封件(15)通过压入而安装到车轮用轴承装置用的外圈构件(12)的轴向的端部(17)的装置。该组装装置(40)具备:柱状的引导构件(41),具有沿周向连续的接触面(44),该接触面(44)从在外圈构件(12)形成的外滚道面(12a)的相反侧与沿着该外滚道面(12a)设置的多个滚珠(13)接触;按压构件(42),在轴向上沿着引导构件(41)向所述轴向的端部(17)侧移动,从而沿轴向按压密封件(15)而将密封件(15)压入到轴向的端部(17);基准构件(43),限制按压构件(42)相对于引导构件(41)的轴向的移动行程。
