Abstract

PURPOSE:To reduce a cost and to easily perform connection work, by providing a connection seat to be formed into an earth member so that it can be connected with and disconnected from a lead wire from car-mounted electrical equipment parts. CONSTITUTION:A battery 9 is mounted to the bottom of a rear seat 4c in a bottom body 4, and a negative electrode of the battery 9 is connected with a forward path 7a of a cooling water pipe 7 by an earth wire 13a. While a speedometer 8a, car radio 8b, head lamps 8c, front directional indicator lamps 8d and cooling fans 8e of electrical equipment parts are mounted to the front part of the bottom body 4, and their negative side terminals are connected with a connection bracket, formed in the forward path 7a or a return path 7b of the pipe 7, by a lead wire 13b. In this way, the necessity for providing an earth member for exclusive use is eliminated because the cooling pipe 7 is used serving also for the earth member, further connection work can be easily performed.
