摘要： This invention relates to a dust preventing structure of a guide unit comprising a track shaft and a sliding member engaging the track shaft via a plurality of rolling bodies such that it is capable of reciprocating in a length direction thereof. Elastic members in firm contact with the track shaft are overlaid in the length direction of the track shaft. A lubricant pocket forming member having a concave groove portion for forming a lubricant pocket constituted of the elastic members and filled with lubricant by a help of the surface of the track shaft as well is provided so as to achieve a smooth reciprocating motion of the sliding member with respect to the track shaft with less sliding friction. Particularly, under even a severe use condition in which use of coolant is required or dust, dirt, wooden pieces, cutting powder or the like falls on the guide unit, a smooth reciprocating motion of the sliding member with respect to the track shaft can be maintained in a long period.
