Title:
LINEAR MOTION GUIDE UNIT
Document Type and Number:
Japanese Patent JP2023127821
Kind Code:
A
Abstract:
To provide a linear motion guide unit which can be reduced in weight, and can improve the assembling performance of the other member to an outer cylinder while suppressing an increase in the number of part items.SOLUTION: A linear motion guide unit comprises a spline shaft having a first raceway surface extending in a longitudinal direction, and provided with a shaft penetration hole penetrating in the longitudinal direction, an outer cylinder relatively movably attached to the spline shaft, and having a second raceway surface opposing the first raceway surface, and a plurality of rolling bodies rolling in a raceway path which is constituted of the first raceway surface and the second raceway surface. The outer cylinder includes an end cap including a return path progressing in parallel with the raceway path, and a direction conversion path for connecting the return path with the raceway path, and an integrated raceway component placed at an outer diameter side of the return path. The raceway component includes a cylindrical part having an inner diameter face at which the second raceway surface is formed, and a flange part protruding to the outer diameter side from an outer diameter face of the cylindrical part.SELECTED DRAWING: Figure 1
