形時の移動を阻止する。In FIGS. 1 to 5, reference numeral 7 denotes a concrete track having a U-shaped cross section, which is constituted by a side wall 7a and a bottom wall 7b. Reference numeral 8 denotes a propulsion coil fixed to the inside of the side wall 7a of the concrete track 7 with a spacer 9 described later.
Is covered with a jacket 8b formed of epoxy resin. 9 is a spacer formed of SMC of short glass fiber reinforced resin,
The propulsion coil 8 is pressed and fixed to the side wall 7a of the concrete track 7 by fastening means 14 described later. 10 is an insert buried in the side wall 7a, 11 is a bolt screwed to the insert 10, 12 is a washer, and 13 is a nut screwed to the bolt 11. The spacer 8 is fixed to the side wall 7a and is propelled through the spacer 8. The coil 8 is fixed to the side wall 7a. In addition, the fastening means 14 is comprised by 11-13. Reference numeral 15 denotes a levitation coil arranged on the center side of the concrete track 7 from the propulsion coil 8, and covers the conductor 15a with a jacket 15b formed of L-SMC made of continuous glass fiber reinforced resin. 16
Is an insert buried in the side wall 7a of the concrete track 7, 17 is a bolt screwed into the insert 16,
The levitation coil 15 is pressed and fixed to the side wall 7a through the fin 8. The fastening means 19 is constituted by 17 and 18. As described in, for example, Japanese Patent Application Laid-Open No. 5-301221, L-SMC of a continuous glass fiber reinforced resin is obtained by arranging continuous glass fibers in a thermosetting polyester resin in a spiral shape so as to have a uniform density. It contains about 40 wt% and is formed into a sheet having a thickness of about 1 to 2 mm. Therefore, since the continuous glass fibers are arranged in a spiral shape, the glass fibers are entangled with each other, thereby preventing movement during pressurization and heat molding.

断調査の成形性とについての検討結果を示す。[0010] Table 1 shows the results of a study on the mechanical strength (bending strength), the appearance of the cured product, and the moldability of the internal cutting inspection when the content of the continuous glass fiber was changed.

However, it is insufficient to secure a margin in strength. On the other hand, if the content exceeds 40 wt% , the fluidity of the resin is poor at the time of production of a molded article, and cavities may be generated inside the molded article to adversely affect the strength. Therefore, the content of the continuous glass fiber is 30 wt% to 40 wt.

疎密になり難いためである。From the results shown in Table 2, the L-SMC of the continuous glass fiber reinforced resin is the same as that of the conventional short glass fiber reinforced resin.
Compared with, the initial strength is improved by about 50% or more, and the long-term strength (plane bending fatigue strength) is improved by about 40%. This is because the continuous glass fibers are arranged in a spiral shape, so that the glass fibers are entangled with each other, so that the movement of the glass fibers is suppressed even if the resin flows during heating and pressurization, and the density of the glass fibers is hardly sparse and dense. It is.
