PROBLEM TO BE SOLVED: To provide an electric power steering device of structure that a thick part for improving the rigidity of a housing and an excess flange part for a bolt hole are unnecessary and reduced in weight. SOLUTION: This electric power steering device is provided with an electric motor 2 to be driven on the basis of the torque detected by a torque detecting device 10 and a worm reduction gear 14 for reducing the rotation speed of the electric motor 2 and transmitting it to rack pinion mechanisms 18 and 19. The torque detecting device 10 is housed in a sensor housing 24a, and the worm reduction gear 14 is housed in a worm housing 25a, and the rack pinion mechanisms 18 and 19 are housed in a rack housing 26a. The sensor housing 24a and the worm housing 25a are fastened by a hollow bolt 11 provided with a through hole 11b in the shaft center part, and the sensor housing 24a, the worm housing 25a and the rack housing 26a are fastened by a bolt 12 inserted into the through hole 11b of the hollow bolt 11.
