A reduction gear mechanism section is disposed inside a casing, and deterioration in meshing of the reduction gear mechanism section due to a load applied by a trunnion member is prevented in a wheel driving apparatus in which the trunnion member supporting a mast of a forklift is disposed on an outer periphery of a casing. A wheel driving apparatus 100 driving a wheel of a forklift, includes a first casing 34; and a first reduction gear mechanism section 101 that is disposed inside the first casing 34. A trunnion disposition portion 34A in which a trunnion member 50 is disposed to support a mast of the forklift is provided on an outer periphery of the first casing 34, and an internal gear 68A that configures the first reduction gear mechanism section 101 is provided on an inner side of the trunnion disposition portion 34A in a radial direction. The internal gear 68A is configured to include an internal tooth element 68 which is independent from the first casing 34. The internal tooth element 68 is fixed to the casing in a state of being provided with a gap 80 with respect to an inner periphery of the first casing 34. |
