    • PROBLEM TO BE SOLVED: To prevent aggravation of intermeshing of a deceleration mechanism unit by the load due to a trunnion member in a wheel driving device in which, while a deceleration mechanism unit being arranged in a casing, the trunnion member which supports the mast of a forklift is prepared at the perimeter of a casing.SOLUTION: A wheel driving device 100 has a casing 34 and a deceleration mechanism unit 101 arranged inside the casing 34, and drives wheels of a forklift. A trunnion arrangement part 34A in which a trunnion member 50 which supports a mast of the forklift is arranged is prepared in the perimeter of the casing 34. An internal gear 68A which constitutes the deceleration mechanism part 101 is formed in the inner side of the radial direction of the trunnion arrangement part 34A. The internal gear 68A consists of an inner teeth body 68 which is a separate body of the casing 34. The inner-teeth body 68 is fixed to the casing 34 with a gap 80 formed therebetween.
    • 要解决的问题:为了防止减速机构单元由于在车轮驱动装置中的耳轴构件的负载而加剧,其中,在减速机构单元布置在壳体中的情况下,支撑桅杆的耳轴构件 在外壳的周边准备了叉车。解决方案:车轮驱动装置100具有布置在壳体34内部的壳体34和减速机构单元101,并且驱动叉车的轮子。 在壳体34的周边配置有配置有支撑叉车的桅杆的耳轴构件50的耳轴配置部34A。构成减速机构部101的内齿轮68A形成在径向内侧 耳轴布置部34A的方向。 内齿轮68A包括作为壳体34的独立体的内齿体68.内齿体68在其间形成有间隙80而固定在壳体34上。
