可能とした構造の要求もされている。 Power for a subway car is generally sent to the motor via a current collector from a rail-shaped third rail arranged along the traveling rail. In other words, the current third
As shown in Fig. 1, the rail is centered around a current collector rail 5, and has a metal bracket 1, an upper plate 2 made of pine wood, and The side plate 3 is fixed. A protection plate 4 is similarly installed in the station building section. These upper plates, side plates, and protective plates are usually treated with insect repellent and antiseptic treatment, but over time they develop cracks, insect bites, corrosion, etc., and become unsafe. Furthermore, communication cables necessary for vehicle operation are housed in troughs and installed at the same location as the rails, or a little away from them, but in order to save space, a structure that allows them to be attached to a protective cover is also required. .

成形法によつて良好裏に実施が可能である。 The present invention was devised in view of the above situation, and the present invention will be explained below based on the drawings showing the embodiments. The main body is made of fiber-reinforced plastic reinforced with fibers of Small semicircular grooves 9 are further provided on both sides of the recess. A communication cable is installed in the groove 9. Reference numeral 10 denotes a lid fitted into a recess provided on the top surface of the main body, which serves to fix the communication cable and also serves to reinforce the main body by tightening bolts to the main body and the bracket at regular intervals. The lid may be made of the same fiber-reinforced plastic as the main body, but it is usually molded by extruding thermoplastics such as polyvinyl chloride or polyolefin resin. Further, the main body 7 can be formed with good accuracy by SMC press molding or pultrusion molding.
