1. A slide guide device comprising:
a guide body comprising a reference guide surface and a sub guide surface that are parallel to each other; a slider comprising a reference slide pad configured to slide on the reference guide surface and a sub slide pad configured to slide on the sub guide surface, the slider being configured to be driven by a drive unit to move along the guide body, wherein the sub slide pad comprises: a sub slide surface that is configured to slide on the sub guide surface; and an auxiliary pressure-receiving surface that is configured to receive a load from the sub guide surface in a non-contact manner with the sub guide surface; and a preload mechanism that is configured to apply a preload between the reference guide surface and the reference slide pad, wherein a formula of N′/N=a/b is satisfied, where: a denotes a distance between a drive axis of the drive unit and the reference guide surface; b denotes a distance between the drive axis and the sub guide surface; N denotes a contact force between the reference guide surface and the reference slide pad; and N′ denotes a contact force between the sub guide surface and the sub slide surface. |
