PROBLEM TO BE SOLVED: To provide a bearing device for a wheel with a load sensor which allows the load sensor to be mounted on a vehicle in a compact manner and detects a load on the wheel stably. SOLUTION: A bearing section 21 comprises an outer member 1 having a raceway surface 4 on its inner circumference, an inner member 2 having a raceway surface 5 facing the raceway surface 4, and a rolling element 3 provided between the both raceway surfaces 4, 5. A joint member 13 is integral with the inner member 2 of the bearing section 21. A pair of encoders 15, 16 are attached to an end section of the inner member 2 and an outer ring 13a of the joint member 13, respectively. Rotation sensors 17, 18 are attached to an end section of the outer member 1 facing the pair of encoders 15, 16 to constitute a rotation sensor section 10. A displacement sensor 24 is provided facing the circumference of the outer ring 13a. COPYRIGHT: (C)2006,JPO&NCIPI
