ABSTRACT:
A linear motion rolling guide unit that obtains high operating accuracy while suppressing sliding resistance to a low level without affecting the mounting state. The bottom surfaces of countersunk portions for insertion of fastening members are formed so as to be positioned, in the direction of said fastening, either on or below a hypothetical extended surface of that one of two bearing surfaces of a track surface that is positioned in said direction of fastening of the fastening member. The opening angle of the track surface is thus not narrowed by the fastening of said fastening members thus allowing high operating accuracy to be obtained and sliding resistance to be suppressed to a low level.
