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. |
