    • Provided is a ball spline enabling easy machining of a spline shaft by drawing and manufacturable at low cost. The ball spline includes a spline shaft in which multiple lines of ball rolling faces are formed along the longitudinal direction; and a spline nut having a hollow hole for inserting the spline shaft therein, formed in a substantially cylindrical shape, having load rolling faces opposed to the ball rolling faces of the spline shaft which are formed in the inner peripheral surface of the hollow hole, and installed on the spline shaft through a large number of balls. The spline shaft is formed in a substantially circular shape in cross section. Multiple lines of torque transmission grooves along the longitudinal direction are formed at equal intervals around the spline shaft, and the ball rolling faces are formed on the lateral both sides of these torque transmission grooves. Further, a distance between a pair of ball rows rolling on both sides of the land parts of the spline shaft is set larger than a distance between a pair of ball rows rolling on both sides of the torque transmission grooves.

    • A dental magnetic attachment, which is embedded in the denture base so as to face a soft magnetic keeper 103 and attract the keeper by magnetic force, comprising at least three yokes which are plates and made of soft magnetic material, and at least two pieces of magnet which have the magnetization direction parallel to the thickness. In the example the attachment comprises a central yoke 10, the magnet 1, the magnet 2, the outer yoke 11, and the outer yoke 12. The invention is characterized by a magnet arrangement in which like poles of the magnet 1 and the magnet 2 faces each other. Because of it mutually independent two magnetic circuits are formed and they offer strong attractive force which is two times larger than that of existing ones in a compact volume required for dental attachment. Furthermore, corrosion resistance and wear resistance are improved by covering the attracting face of the magnet 1, 2 with spacers made of non-magnetic material and covering the whole attachment with the cap made of non-magnetic material except the attracting face of the attachment.
