すなわち、図２に示すように、端子組付け部２０において、接続ピン１６の外周との隙間に水が浸入しても、接続ピン１６中間部に設けた第一の密封部材（Оリング）２１により防水して、機器ケース２内部へ水が浸入するのを防止することができる。 That is, as shown in FIG. 2, even if water enters the gap between the outer periphery of the connection pin 16 and the terminal assembly portion 20, the first sealing member (O-ring) 21 provided in the middle portion of the connection pin 16 is provided. Thus, it is possible to prevent water from entering the inside of the device case 2 by waterproofing.

４）コイルバネ１７によって、接続ピン１６とマイナス端子１３との接続不良を防止することができる。 4) The coil spring 17 can prevent a defective connection between the connection pin 16 and the negative terminal 13.

５）支持部材１４の円筒部１５に設けた切欠き状の水抜き孔１５ａによって、円筒部１５内のマイナス端子１３部分から水を外部へ抜くことができる。 5) Water can be drained to the outside from the minus terminal 13 portion in the cylindrical portion 15 by the notch-shaped drain hole 15a provided in the cylindrical portion 15 of the support member 14.
