Article 10 is provided. The hitting ridge 10 is composed of a vertical hitting ridge 10a and a plurality of horizontal hitting ridges 10b over substantially the entire length at the center, and is divided by adjacent horizontal hitting ridges 10b and a vertical hitting ridge 10a. The terminal block 11 slides freely within the range. The heaters 4 are connected to the terminal blocks 11 by lead wires 21, respectively. The lead wire 21 is formed of a flexible electric wire. The lead wires 21 are collectively stopped by the tension stopper 12. As described above, when the tension stoppers 12 are combined, abnormal force is not applied and there is no fear of disconnection or the like. The terminal block 11 is provided with a quick connection terminal 13 for quickly connecting a power supply line 22 such as a VV cable such as a power supply line or a feed line.

As shown in FIG. 5, the quick-connecting terminal 13 is locked with a terminal plate 14
15 and formed by inserting a conductor 22a of a power supply line 22, such as a VV cable such as a power supply line or a feed line, so that the terminal plate 14 and the lock spring 15 can be sandwiched and connected. Has become. Notches 16 are provided on both sides of the upper portion of the terminal block 11 to form a convex portion 17, and a female screw hole 18 is formed on the upper surface of the convex portion 17.
