摘要： A ball screw device having a novel ball circulation structure suitable for a screw shaft with a large lead, optimum for downsizing and weight saving of a nut member, capable of being manufactured at low cost, and capable of exhibiting high reliability even under severe use conditions. In a ball screw device where a screw shaft and a nut member are screwed to each other through an intermediation of a large number of balls, a no-load ball path which forms an infinite circulation path for the balls is constituted by a no-load ball groove spirally formed in an inner peripheral surface of a through-hole of the nut member and by a pair of direction change grooves which communicatively couple a load rolling groove and the no-load ball groove to each other so as to complete the infinite circulation path as a closed loop.

摘要： A reciprocating device has a construction, in which a slider is formed by fixing a table member to a bearing casing which is movable inside a track bed having a C-shaped section in a longitudinal direction thereof, and a continuous drive is disposed along the track bed for reciprocating the slider. A weight and sizes of the device can be reduced, and reciprocating motion without a pitching motion can be achieved. Accordingly, the invention can prevent generation of uncomfortable noises during a movement of the slider, and also can prevent reduction of durability of the device which may be caused by irregular wear of a bearing for guiding the slider.
