<p>Provided is a motion guide device having a low rigidity in the vertical direction and a low rigidity in the horizontal direction. The motion guide device has: a raceway rail 15 having a bottom surface 30a, side surfaces 30b and an upper surface 30c and being mounted on one of a base 12 and a moving body 11; and a moving block 16 having a center portion 16a facing the upper surface 30c of the raceway rail 15 and side wall portions 16b facing the side surfaces 30b of the raceway rail 15 and being mounted linearly or curvilinearly movable relative to the raceway rail 15. On a side surface of the moving block 16, a displacement absorbing mechanism 17, 38 is provided. The displacement absorbing mechanism 17, 38 has a mounting member 26, 34 mounted on an opposite one of the base 12 and the moving body 11, and a displacement absorbing portion 31, 37 which is fixed to the mounting member 26, 34 and which is shear-deformed when the mounting member 26, 34 is displaced in a direction crossing an upper surface of the moving block 16.</p> |
