To perform loosening prevention for a nut member to a male screw part of a stationery side housing.SOLUTION: A travel device 11 comprises: a stationery side housing 12; a hydraulic motor 14; a rotary side housing 17; bearings 19, 20 which are provided between the stationery side housing 12 and the rotary side housing 17; planetary gear reduction mechanisms 22, 28 which decelerate rotation of the hydraulic motor 14; a nut member 35 which is engaged with a male screw part 12E of the stationery side housing 12, and position the bearings 19, 20; and a loosening prevention mechanism 36 which suppresses loosening of the nut member 35. The loosening prevention mechanism 36 comprises a concave groove 37 which is formed at an inner peripheral edge of the nut member 35, a female screw hole 38 which is formed in an end face 12G on the other side in an axial direction of the stationery side housing 12 at a position corresponding to the concave groove 37 of the nut member 35, and a fixing bolt 39. In the state that the fixing bolt 39 is screwed into the female screw hole 38, a head 39B of the fixing bolt 39 is engaged with the concave groove 37 of the nut member 35.SELECTED DRAWING: Figure 3
【課題】固定側ハウジングの雄ねじ部に対するナット部材の緩止めを行う。【解決手段】走行装置１１は、固定側ハウジング１２と、油圧モータ１４と、回転側ハウジング１７と、固定側ハウジング１２と回転側ハウジング１７との間に設けられた軸受１９，２０と、油圧モータ１４の回転を減速する遊星歯車減速機構２２，２８と、固定側ハウジング１２の雄ねじ部１２Ｅに螺合し軸受１９，２０を位置決めするナット部材３５と、ナット部材３５の緩みを抑制する緩止め機構３６とを備える。緩止め機構３６は、ナット部材３５の内周縁に形成された凹溝３７と、ナット部材３５の凹溝３７に対応する位置で固定側ハウジング１２の軸方向の他側の端面１２Ｇに形成された雌ねじ穴３８と、固定ボルト３９とを備え、固定ボルト３９が雌ねじ穴３８に螺着された状態で固定ボルト３９の頭部３９Ｂがナット部材３５の凹溝３７に係合する。【選択図】図３
