The stationary rail has a first bottom wall portion, first inside wall portions vertically upwardly extending from side ends of the first bottom wall portion, upper wall portions outwardly extending from upper ends of the first inside wall portions, and first outside wall portions vertically downwardly extending from outer ends of the upper wall portions. Each of the upper wall portions is grooved at a major portion thereof for receiving ball bearings thereon and convexly curved at a rear end portion thereof. The major portion and the rear end portion are united. The movable rail is axially slidably engaged with the stationary rail and has an upper wall portion, second outside wall portions vertically downwardly extending from side ends of the upper wall portion, second bottom wall portions inwardly horizontally extending from lower ends of the second outside wall portions, and second inside wall portions vertically upwardly extending from inner ends of the second bottom wall portions. The stationary and movable rails are so assembled that each of the second inside wall portions of the movable rail is spacedly put between the corresponding first inside and outside wall portions of the stationary rail.
