Abstract
A linear motion guide unit includes a rail, a slider slidable relative to the rail, and rolling elements rollable in a rolling groove formed with the rail and the slider. The slider has a lubricating oil supply device provided at least at one end face thereof. The lubricating oil supply device includes a lubricating member that retains lubricating oil and abuts against a raceway surface of the rail to supply the lubricating oil to the rail, a housing having front, rear, and bottom surfaces covering front, rear, and bottom surfaces of the lubricating member, with an upper surface of the housing being left open, and a cover that covers at least an upper surface of the lubricating member. The housing is fixed to the slider with a first fixing member. The cover is fixed to the housing with a second fixing member, without being fixed with the first fixing member.
