THIN SLIDE UNIT

摘要

A thin slide unit where an endless circulation path for balls is constructed by combining two ball plates having track-like ball grooves formed in them, wherein the balls are smoothly circulated in the unit constructed only by directly joining the two ball plates without use of a guide plate, thereby smooth reciprocation of a slider relative to a guide rail is realized. The endless ball circulation path of the slider is constructed by setting the two ball plates, having track-like grooves formed in them, opposite to each other and directly joining the ball plates together. When edge sides of the two ball plates are placed opposite to each other, a load opening for causing the balls in the endless circulation path to be in contact with a rolling groove of the guide rail is formed and, also, a scooping-up section for lifting the balls from the rolling groove to guide them into the endless circulation path is formed.
