  However, in recent years, there has been a demand for the realization of a weight-reduced device in response to a request for expanding the application range of motion guide devices in recent years, and an idea for weight reduction has been proposed to meet this demand. For example, Patent Document 1 below discloses an invention characterized in that an aluminum alloy is used as a member constituting a guide rail as a track member for the purpose of reducing the weight of the linear guide device.

  However, in the invention described in Patent Document 1 below, since the main members of the motion guide device are made of a metal material as in the prior art, there is a limit even if a certain amount of weight reduction can be achieved. It was difficult to meet the demand for weight reduction.

  On the other hand, FRP (Fiber Reinforced Plastics) is known as a material that has the same strength and rigidity as metal materials such as steel, and that also achieves weight reduction. This FRP can reinforce plastics by using fiber and resin and can significantly improve the strength, so it can be used in various fields such as the space and aviation industries, motorcycles, automobiles, railways, construction industries, medical fields, etc. It is the material used. The applicant of the present application has been diligently researching a technique for applying FRP to constituent members of a motion guide device, and has created various inventions disclosed in, for example, Patent Document 2 below.

  In the manufacturing method of the track rail 11 according to the present embodiment, first, a mold / outer layer member preparation step (step S10) for preparing the two mold / outer layer members 32 (321, 322) is performed. The die / outer layer member 32 (321, 322) includes an outer side (321) and an inner side of the track rail 11 having a substantially U-shaped longitudinal section, as shown in a partial diagram (a) in FIG. It is a member which comprises (322), and is comprised as an extrusion material of an aluminum alloy.

By performing a chemical or physical surface treatment, a surface treatment step (step S11) for forming an uneven shape on the surface of the mold and outer layer member 32 (321, 322) is performed. In this surface treatment step (step S11), as shown in a partial diagram (b) in FIG. 5, the two die / outer layer members 32 (321 and 322) are positioned on the outer side of the track rail 11. With respect to the mold / outer layer member 321 on one side to be performed, surface treatment is performed on the surface on the upper surface side, and the mold / other layer on the other side that is positioned on the inner side of the track rail 11 is also performed. The outer layer member 322 is subjected to surface treatment on the lower surface. That is, the surface treatment is performed on the surface to which the prepreg laminate 31 described later is bonded. In the surface treatment process (step S11) according to the present embodiment, the surface of the mold / outer layer member 32 (321, 322) is chemically roughened by using a chemical such as an acid, so that a concavo-convex shape at a microscope level is obtained. Forming is performed on the mold / outer layer member 32 (321, 322). In this way, by forming a fine uneven shape at the microscope level, an adhesive for prepreg adhesion applied in a subsequent process enters the uneven shape and adheres to the die / outer layer member 32 (321, 322). The contact area with the agent is increased, and a strong bonded state is realized.

  Next, of the two mold / outer layer members 32 (321 and 322), the prepreg 311 is bonded to the surface of the one mold / outer layer member 321 that has been subjected to the surface treatment using an adhesive.

The two mold / outer layer members 32 (321, 322) are used as an upper mold (322) and a lower mold (321) arranged above and below, and heated while applying pressure in the vertical direction, so that prepreg lamination The body 31 is molded as FRP having a predetermined strength. In the FRP molding method according to the prior art, a metal mold such as aluminum is prepared, and heating / pressurization processing is performed using this mold. However, the heating / pressurizing process according to this embodiment is performed. In the pressure process (step S14), the technique using the mold / outer layer member 32 (321, 322) constituting the outer periphery of the track rail 11 as a mold is adopted, so the number of manufacturing steps can be reduced and the productivity can be reduced. And is excellent in terms of cost. In addition, as a specific method of the heating / pressurizing step (step S14) according to the present embodiment, if a method using the die / outer layer member 32 (321, 322) as a die can be adopted, a conventionally known FRP manufacturing is possible.

It does not occur. Therefore, according to this embodiment, the trouble of the additional work for correcting the malfunction which generate | occur | produces in FRP can be eliminated, and the reduction effect of manufacturing cost can be acquired. Further, according to the present embodiment, the two mold / outer layer members 32 (321, 322) may be processed for fixing with other members. It can be said that the configuration has very few restrictions. That is, in comparison with the conventional technique in which taps and holes are provided in the FRP, it is better to provide taps and holes in the mold / outer layer member 32 (321, 322) made of an aluminum alloy as in this embodiment. Excellent in strength. Further, in the processing for the die / outer layer member 32 (321, 322) made of an aluminum alloy, it is not necessary to perform processing in consideration of the direction of the fiber unlike the processing for FRP.
