Abstract

PURPOSE:To achieve low floating without causing attraction phenomena by positioning the centers of the respective radius of curvature of the cylindrcial floating faces of the floating parts provided by being bisected in the front and back in the lngitudinal direction of a slider within the range of the length of each floating part. CONSTITUTION:Front and rear floating parts 4a, 4a' and 4b, 4b' bisected to the front and rear are provided to both lower ends of a slider 1, and respectively cylindrical floating faces 8, 9 are formed to these, In this case, the floating faces are so formed that with the central positin of the radius of curvature of the floating faces 9 as the front end of the floating part the faces subsequently rise as they go toward the rear part, in contrast with which with the central position of the radius of curvature of the floating faces 8 as an approximate center the faces mildly rise toward both front and rear sides. The similar cylindrical faces 12, 13 are also formed on the protrusions 10, 11 which guide the flow of air and a core 2 is buried in the recess 14 at the end of the slider 1 so that a gap 3 is positioned to the approximate center of the floating parts 4a, a'. Thereby, low floating may be achieved without causing attraction phenomena.
