在车轮用轴承装置(1)中,在外侧构件(2)的外侧端部的外周设置有以内侧构件(3)的旋转轴(L)为中心的圆环状的堰部(20),堰部(20)被设为在外侧构件(2)的上半部分侧(Us)与下半部分侧(Ls)非对称的形状,上半部分侧(Us)的一部分或所有部分的堰壁面(20a)随着朝向径向外侧而向内侧倾斜。并且,堰部(20)的下半部分侧(Ls)的一部分或所有部分的堰壁面(20a)随着朝向径向外侧而向外侧倾斜。

    A bearing device 1 for a vehicle wheel, wherein an annular weir part 20 is provided on the outer periphery of an outer-side end part of an outer member 2, the annular weir part 20 having the rotation axis L of an inner member 3 as a center, the weir part 20 having a shape that is asymmetrical between the upper side Us and the lower side Ls of the outer member 2, and the weir part 20 being inclined farther toward the inner side the more a weir wall surface 20a faces outward in the radial direction in a part or all of the upper side Us. Also, the weir part 20 is inclined farther toward the outer side the more the weir wall surface 20a faces outward in the radial direction in a part or all of the lower side Ls.
