ring runner 80. Aring runner 80 is integrally formed by a synthetic resin and is constituted by an attachingportion 80B horizontally extended to be able to fix to themovable element 50, aring portion 80C surrounding the outer periphery of theouter rail 20 as shown by Fig. 1(A), a connectingportion 80D for connecting the attachingportion 80B and thering portion 80C, and ahanging portion 80A for hanging a curtain arranged at the lower end of thering portion 80C. The connectingportion 80D is extended downwardly from anopening groove 20h formed at the lower end of theouter rail 20 to support thering portion 80C as shown by Fig. 1(A). - As illustrated by Fig. 3, screw holes 50a, 50b and 50c are perforated at the lower end of the
movable element 50. Meanwhile, screw holes 80a, not illustrated, 80b and 80c are perforated also at the attachingportion 80B of thering runner 80. Thering runner 80 is fixed to themovable element 50 by fasteningscrews 84 to the screw holes 50a, 50b and 50c and thescrew holes 80a, 80b and 80c. - Next, an explanation will be given of opening and closing operation of a curtain by the linear motor of the first embodiment in reference to Fig. 4 (A) and Fig. 4(B). The
forefront ring runner 80 at the left end in Fig. 4(A) is fixed to themovable element 50 as explained above in reference to Figs. 1(A), 1(B), 2 and 3 andother ring runners outer rail 20. Also, acurtain 90 hangs down from thering runners - When an opening and closing switch, not illustrated, of the curtain is operated and electricity is supplied to the
cable 30 shown by Fig. 2, current is made to flow to therespective armatures movable element 50 via thebrushes 54 and magnetic fluxes are generated. A thrust in the right direction of Fig. 4 (A) is generated in themovable element 50 by the mutual action of the magnetic fluxes of therespective armatures permanent magnets 42 whereby running in the right direction is started. Theforefront ring runner 80 is moved in the right direction along with the running of themovable element 50 and presses thering runner ring runners outer rail 20 whereby thecurtain 90 is opened. - According to the linear motor of the first embodiment, different from the linear motor of the conventional technology described above in reference to Fig. 7, the
ring runner 80 is fixed to the movable element and therefore, thering runner 80 is not inclined and is not twisted in respect of the outer rail. Therefore, thecurtain 90 can be opened and closed by abrasively moving thering runner 80 smoothly on theouter rail 20. - An explanation will be given successively of a second embodiment of the present invention in reference Fig. 5.

The connecting portion 180D is extended downwardly from anopening groove 120h formed at the lower end of theouter rail 120 to support thering portion 180C. Similar to the first embodiment explained above in reference to Fig. 3, thering runner 180 is fixed to themovable element 50 by fastening screws to screw holes, not illustrated, of themovable element 50 and screw holes, not illustrated, formed at the attaching portion 180B of thering runner 180. - Also in the linear motor of the second embodiment, the
ring runner 180 is fixed to themovable element 50 and therefore, thering runner 180 is not inclined and is not twisted in respect of theouter rail 120 in opening and closing the curtain. Therefore, thering runner 180 is abrasively moved smoothly on theouter rail 120 whereby a curtain can be opened and closed. - Incidentally, although in the first embodiment, the example of using the cylindrical
outer rail 20 and the ring-like ring runner 80 has been described and according to the second embodiment, the example of using theouter rail 120 having a square prism shape and thering runner 180 having a square shape has been described, it is possible in the present invention to use outer rails having various shapes of a triangular shape, a pentagonal shape, a hexagonal shape and the like and ring runners having various shapes surrounding outer peripheries of the outer rails. Also, although the magnet movable type linear motor is exemplified in the first and the second embodiments, the present invention is naturally applicable to a linear motor of a coil movable type. - As described above, according to the linear motor type curtain opening and closing devices of the present invention, the ring runner is fixed to the movable element and therefore, the ring runner is not twisted in respect of the
outer rail 20 whereby the curtain can be opened and closed smoothly.
