Another end of the supporting arm is pin connected to a suspension arm, and another end of the suspension arm is pin connected to a fixing mount that enables fixing to a bottom portion of the upper cover. An oil pressure rod is pin configured between the aforementioned supporting arm and the base mount, thereby providing support therebetween. Accordingly, good support and buffering effectiveness is achieved when opening and closing the upper cover.
