Abstract:
[Problem] To provide a motor unit, a vehicle steering device, and a motor mounting structure capable of inhibiting vibrations generated by a motor from being transmitted to a mounting body even while retaining support stiffness of the motor by mounting a motor case to the mounting body by using a fastening member. [Solution] Mounting a motor case 44 of a motor 4, in which a stator 41 and a rotor 42 are accommodated in the motor case 44, to a housing 6, that serves as a mounting body, by using a bolt 7. The motor case 44 includes: a cylindrical part 441 that accommodates the stator 41; and a bottom part 443 that is provided so as to protrude radially inward from one end of the cylindrical part 441. A fastening part 445 for receiving the bolt 7 is provided to the bottom part 443 inward of the outer circumferential surface 441a of the cylindrical part 441.
