An electric hub device includes a hub body 26 rotatable with respect to hub shafts 24 and 25 and a motor 27 that rotate the hub body 26. The motor 27 includes a rotating body 32 provided with a rotating shaft 37 and a housing 34 accommodating the rotating body 32. The rotating shaft 37 and the hub body 26 move in synchronization with each other via a speed reduction mechanism 48. The speed reduction mechanism 48 includes a sun gear 49 formed on the rotating shaft 37, an annular gear 50 provided in the hub body 26, and rotatable planetary gears 51 that mesh with the sun gear 49 and the annular gear 50. The housing 34 has a recess 45 that is dented inward in an axial direction A of the hub shafts 24 and 25. The sun gear 49, the annular gear 50, and the planetary gears 51 are placed in the recess 45. |
