An electric power path (electric power cable) 58 is laid from a relay box 50 to an electric actuator 31 for back bottom a 22 and an electric actuator 34 for a leg bottom 26 so as to supply electric power via the path. Electric actuator 31 or 34 can be driven depending on selection of insertion to socket 50b or 50b in this relay box 50.
