Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a hub unit which can discharge water intruding into a space between a brake rotor and an annular groove.SOLUTION: A hub unit H comprises an outer member 1, and an inner member 2 which is coaxially arranged at the outer member at the inside of the outer member. A wheel attachment flange 11 for fixing wheels via a brake rotor 4 is formed at the outer member or the inner member, a plurality of bolt holes 12 which hub bolts 13 for fixing the wheels penetrate are formed at the wheel attachment flange along a circumferential direction, and an annular groove 16 including a plurality of the bolt holes is formed at a flange face 11a of the wheel attachment flange at a side to which the brake rotor is attached. A drain groove which communicates with the annular groove, and extends to the outside of a radial direction is formed at the flange face. 【課題】ブレーキロータと環状溝との間のスペースに侵入した水を排出することができるハブユニットを提供する。【解決手段】外輪部材１と、この外輪部材の内方において当該外輪部材と同軸に配設された内輪部材２とを備えており、前記外輪部材又は内輪部材に、ブレーキロータ４を介して車輪を固定する車輪取付用フランジ１１が形成されており、この車輪取付用フランジに、車輪を固定するためのハブボルト１３が挿通する複数のボルト孔１２が周方向に沿って複数形成されており、かつ、前記ブレーキロータが取り付けられる側の前記車輪取付用フランジのフランジ面１１ａに、前記複数のボルト孔を含む環状溝１６が形成されているハブユニットＨ。前記フランジ面に、前記環状溝と連通しており、かつ、径方向外側に延びる排水溝が形成されている。【選択図】図１
