In the figure, 1 is the raceway axis, 3 is the raceway groove, 5 is the wayway, 13 is the recess, 15 and 17 are the rolling grooves, 23 is the rolling element, 25 is the circulation path, 27 is the slit, and 29 is the shortest distance. It is a part.

Claims (1)

[Scope of utility model registration request] The track shaft 1 has axial track grooves 3 on both sides in the direction perpendicular to the shaft, and the track base 5 disposed opposite to the track shaft 1 has a recess 13 in the axial direction.
has rolling grooves 15 and 17 facing the raceway groove 3, and a large number of rolling elements 23 disposed between the rolling grooves 15 and 17 and the raceway groove 3 form a circulation path 25 provided in the raceway base 5. In the linear guide which can be circulated through the track 5, the way 5 has an axial slit 27 in the axial middle part, and the shortest distance between the deep part of the slit 27 and the inner and outer surfaces of the way 5 is A linear guide characterized in that the portion 29 is elastically deformed by the rolling elements 23 pressing against the rolling grooves 15 and 17.
