PROBLEM TO BE SOLVED: To prevent the entry of dirt into a sliding body and also prevent the leakage of oil from the inside of the sliding body by seal members. SOLUTION: This sliding device comprises a shaft 1, the sliding body 2, and rolling elements 3 installed between the shaft 1 and the sliding body 2. Lubricating oil is held in the sliding body 2, and the seal members 4a and 4b are arranged parallel with each other at the end of the sliding mechanism in the sliding direction. The lip parts 5a and 5b of the seal members 4a and 4b in contact with the shaft 1 are formed to tend to be curved when a force acts thereon from one side in the sliding direction and hard to be curved when the force acts thereon from the other side. The device comprises the lip part 5a as the outer seal member 4a which, when a force acts thereon from the outside, tends to bent inward and, when the force acts thereon from the inside, hard to be bent outward and the lip part 5b as the inner seal member 4b which, when the force acts thereon from the inside, tends to be curved outward and, when the force acts thereon from the outside, hard to be curved inward.
