A linear guide apparatus includes a base, a movable member movable to the base, first and second guide receptacles on the movable member, first and second linear guide members, being parallel to each other and received by the first and second receptacles to guide movements of the first and second receptacles, the first guide being fixed on the base and the second guide being arranged on the base, and a pre-load adjusting unit, provided on the base, for supporting the second guide to be movable in parallel to the first guide and for adjusting a distance between the first and second guides, thereby adjusting a pre-load applied between the guides and the receptacles of the movable member. The adjusting unit has a stationary projection fixed on the base, a pre-load block, and pivot angle adjusting mechanism. The block has a recess pivotally seated on the projection to change a pivot angle around the projection, and contacts the second guide, thereby moving the second guide to change the distance between the first and second guides, and the pivot angle adjusting mechanism is adjustable the pivot angle of the block.
