Patent ID: 6848326

Claim:
A linear guide apparatus comprising: a guide member including a guide surface formed on an outer surface thereof; a slider disposed on said guide member so as to be movable along a longitudinal direction of said guide member and including a load guide surface formed so as to face said guide surface of said guide member; a brake member disposed so as to face a side surface of said guide member and so as to be contactable with portions of said side surface of said guide member other than said guide surface; a drive device including an advance and retreat member movable in a direction toward and away from said side surface of said guide member, said drive device being capable of driving said advance and retreat member in the direction toward said side surface of said guide member to thereby press said brake member against said side surface of said guide member and also capable of driving said advance and retreat member in the direction away from said side surface of said guide member to thereby remove the pressure thereof; and a resilient support member disposed substantially parallel with said side surface of said guide member so as to allow a clearance between said side surface and said brake member, wherein said support member is supported in longitudinal and vertical directions of the guide member with a rigidity that is higher than a rigidity with which it is supported in said direction toward and away from said side surface of said guide member.
