PURPOSE:To eliminate an impact and a vibration from start to finish in motion of a slider, by forming a rack in the slide, while installing a roller, and installing a pinion to be engaged with the rack and a plate cam both in a rotary shaft. CONSTITUTION:A rack 7 is formed on the side facing on a rotary shaft 1 of a slider, and each of rollers 10, 11 and 12 is set up in front and rear parts of the rack, while a pinion 14 to be engaged with the rack 7 and plate cams 8 and 9 feeding these rollers 10, 11 and 12 both are installed in this rotary shaft 1. With this constitution, with these plate cams 8 and 9, the slider 5 performs gentle acceleration or deceleration so that an impact and a vibration from start to finish in motion of the slider 5 are eliminable. |
