The front plate portion 11b and the rear plate portion 11d are formed so as to face each other substantially in parallel, and are formed slightly inside from the edge of the long side of the upper plate portion 11a, and the outer surface of the tip portion is tapered. A portion is formed, and is formed into a shape that can be easily inserted into a slide groove of the lead-out portion 10 described later. Further, a horizontally long engagement protrusion 11c that protrudes forward is formed in the lower portion of the front surface of the front plate portion 11b. Both sides of the engaging protrusion 11c are formed as hypotenuses, and the upper and lower sides are formed in tapered portions that become thinner toward the tip. Further, a plurality of anti-slip protrusions 11e made of rod-like protrusions that are substantially parallel to each other are formed on the upper surface of the upper plate portion 11a.

FIG. 10 is an enlarged perspective view showing the configuration of the lead-out portion 10 formed on the front surface portion 3c of the case body portion 3. As shown in FIG. However, a blank panel 11 is attached to the lead-out portion 10, and the configuration of the engagement portion 8 is omitted.
As shown in this figure, the lead-out portion 10 is formed so as to protrude from the front surface portion 3c to the front surface side by the width of the side surface portion 10e, and a power source is provided between the front surface portion 10d and the front surface portion 3c facing the front surface portion 10d. A first insertion portion 10b having a semicircular deep groove at the lower end through which the cable 6 is inserted and a second insertion portion 10c having a semicircular shallow groove at the lower end through which the ground cable 7 is inserted have a predetermined interval.
