摘要： PROBLEM TO BE SOLVED: To remove the backlash of a hypoid gear device. SOLUTION: The hypoid gear device 1 comprises a backlash removing means for removing backlash between a driven large gear 8 and a driving small gear 7 meshing with the driven large gear. The backlash removing means has a driven small gear 11 arranged coaxially on the driving small gear 7 for meshing with the driven large gear 8 and an elastic body 12 for energizing the driven small gear 11 coaxially in the opposite direction to the driving small gear 7. Because the driving small gear and the driven small gear are energized coaxially in mutually opposite directions by the elastic body, the driving small gear has contact with one toothed face of the driven large gear and at the same time the driven small gear has contact with the opposite toothed face of the driven large gear, resulting in the removal of backlash.

摘要： PROBLEM TO BE SOLVED: To prevent generation of noise at the time of motion of a nut as much as possible by constituting a rectilinear guide device of a dampely on an material formed of a material having elasticity and contacted closing inner circumferential surface of a shaft main body and a presser member to adhere on an inner circumferential surface of this damping material. SOLUTION: When a spline nut 2 moves along a spline shaft 1, a ball 3 is circulated from a no-load ball guide groove 23 to a load ball guide groove 21 in the spline nut 2 and makes contact with a ball rolling surface 11 of the spline shaft 1 in succession, and accordingly, the spline nut 2 is excited and generates oscillating sound. Therefore, the spline shaft 1 is constituted of a shaft main body 6 having the ball rolling surface 11 and formed hollow cylindrical, a damping materiel 7 formed of a material having viscoelasticity and to cover an inner circumferential surface of the shaft main body 6 and a hollow cylindrical presser member 8 to sandwich this damping material 7 between itself and the shaft main body 6, and it is devised to absorb oscillating energy given to the spline shaft 1 by collision of the ball 3 by the damping material 7.

摘要： PROBLEM TO BE SOLVED: To provide a rolling guide device capable of realizing smooth roller circulating motion by preventing a malfunction caused by a skew of rollers. SOLUTION: This rolling guide device 10 is provided with a track member 11, a moving body 12 installed on the track member 11 in a state relatively movable in the lengthwise direction and a large number of rollers 16 interposed between the track member 11 and the moving body 12. The rollers 16 are loaded in an infinitely circulating passage composed of a load rolling traveling passage 40 formed between the track member 11 and the moving body 12, a return passage 41 arranged on the moving body 12 in parallel to the load rolling traveling passage 40 and a direction changing passage 42 for connecting the load rolling traveling passage 40 and the return passage 41. Pressing parts 50, 50 for pressing down the rollers 16 toward the central side from the axial directional both end sides are arranged in a connecting part of the direction changing passage 42 to the load rolling traveling passage 40.
