Abstract:
A linear guide mechanism having a base member and a slider which are displaceable relatively linearly, said linear guide mechanism comprising:a horizontal surface guide track and an inclined surface guide track which are formed in an axial direction of said base member; a first load-receiving element which is provided for said slider and which is engaged with said horizontal surface guide track; and a second load-receiving element which is provided for said slider and which is engaged with said inclined surface guide track, wherein an angle, which is formed by an axis of said first load-receiving element and an axis of said second load-receiving element, is &thgr;, a load-bearing capacity of said first load-receiving element is RA, and a load-bearing capacity of said second load-receiving element is RB; and &thgr;, RA, and RB are set so that 45Â°&lE;&thgr;<90Â° and 1.2&lE;RB/RA&lE;2.7 are satisfied, and thus each of load resistances of said first and second load-receiving elements is substantially constant in a predetermined direction even when attachment postures of said base member and said slider are changed.
