Abstract

L'objectif de la présente invention se rapporte à un dispositif de guidage linéaire qui n'est enclin ni à des insuffisances de lubrification ni à des fuites de lubrifiant depuis l'intérieur d'un coulisseau vers l'extérieur. Dans ce dispositif de guidage linéaire, un matériau d'absorption de lubrifiant (20) est disposé entre un rail de guidage (1) et un coulisseau (2), si bien que, si trop de lubrifiant est apporté à l'intérieur du coulisseau (2), le lubrifiant s'écoulant dans un espace situé entre la surface supérieure (1b) du rail de guidage (1) et la surface intérieure (7a) d'une pièce en forme de plaque (7) du coulisseau (2) est absorbé. Cela rend difficiles l'accumulation de lubrifiant dans ledit espace et la fuite de lubrifiant de l'intérieur du coulisseau (2) vers l'extérieur.
