PROBLEM TO BE SOLVED: To miniaturize a vehicular steering device regarding an axial direction of a turning shaft. SOLUTION: A ball nut 31 of a ball screw mechanism 25 is rotated by an electric motor 23 through a speed reduction mechanism 24. A rack shaft 10 is moved in an axial direction X1. A double-row angular contact ball bearing 41 supported by a first housing 42 rotatably supports the ball nut 31. The speed reduction mechanism 24 includes an annular speed reduction gear 34 mounted to the ball nut 31 so as to rotate together therewith. At least a part of a rack stopper 59 formed at a second housing 43 is arranged at an inner side in a radial direction of the speed reduction gear 34. COPYRIGHT: (C)2010,JPO&INPIT
