LINEAR MOVEMENT GUIDE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a linear movement guide device which can seal between a guide member and a slider member securely without increasing the sliding resistance, and can suppress the rise of the cost. SOLUTION: A linear movement guide bearing device 1 as a linear movement guide device has a guide rail 3 and a slider 4. The guide rail 3 forms plural rotor rolling grooves 5 on its outer surface. The slider 4 has a slider main body 6. The slider main body 6 has load rotor rolling grooves 8 opposing to the rotor rolling grooves 5 respectively. The slider main body 6 is provided with the first seal member 20 at the bottom surface 12 of its both skirt parts, and the second seal member 21 at the inner side horizontal wall surface 11 held by the both skirt parts. The first and the second seal members 20 and 21 have lip parts 24 and 34 abutting to the guide rail 3 respectively. The lip parts 24 and 34 have thick wall parts thicker than the bottom parts and the front end parts, on the way going from the bottom parts to the front end parts.
