To provide a pinion shaft support device for a vehicle of a low operation cost and low rolling viscosity resistance of an anti-friction bearing supporting the pinion shaft.
Thermoelectric elements 40, 41, 42, 43 are arranged on an outer circumference surface of outer rings 24, 25 of taper roller bearings 5, 6 arranged on a pinion shaft 1 and metal joining parts of a first and a second thermo couples are arranged. Also, a microcomputer receiving signal from the first and the second thermo couples and outputting control signal to the thermoelectric elements 40, 41, 42, 43 is installed on an outside of a case 8. The microcomputer receives signal indicating temperature of the outer rings 24, 25 from the thermo couples, and outputs control signal to drive the thermo couples 40, 41, 42, 43 to the thermo couples 40, 41, 42, 43 when temperature of the outer rings 24, 25 is lower than predetermined temperature.
