To provide a method for mounting an outer sleeve onto a housing in low cost and with high precision in a linear sliding apparatus, the linear sliding apparatus has a shaft, and the outer sleeve is fitted around the shaft and slidable in a linear manner relative to the shaft. The method includes the steps of: engaging any desired position of an outer circumference of the outer sleeve with a stationary member in a convex and concave engagement; and fixing the stationary member to the housing by a fastening member, thereby mounting the outer sleeve on the housing.
