Title:
LUBRICANT SUPPLY BODY, AND LINEAR MOTION GUIDE DEVICE COMPRISING LUBRICANT SUPPLY BODY
Document Type and Number:
Japanese Patent JP2023155708
Kind Code:
A
Abstract:
To provide a lubricant supply body capable of adding functions other than lubricant supply and reducing a weight, while securing an amount of oil released to lubrication portions such as rails, and a linear motion guide device comprising the lubricant supply body.SOLUTION: A lubricant supply body is provided at an end part of a linear motion body that moves straight in an axial direction, and supplies lubricant in contact with a lubricated portion. In the lubricant supply body, a protrusion part 17 is formed so as to have the same end surface shape as an end surface shape of the linear motion body, and includes a region that is in contact with the lubrication portion and protrudes thickly in a stepped shape on a surface part perpendicular to the movement direction of the linear motion body. The entire supply body or at least the protrusion part is made of a lubricant-containing polymer member, and a stepped space 19 is formed above the protrusion part.SELECTED DRAWING: Figure 3
