A protective guard member is provided in order to protect a high-voltage wire connected to a control unit in an electric vehicle, in which the control unit, for controlling a drive motor of the vehicle, is mounted to a rear swing arm thereof. The high-voltage wire protecting guard member may be provided as a guard arm of a main vehicle support stand, arranged to shield the external side of the high-voltage wire, when the support stand is in a stored position thereof. The guard arm may be configured to protectively shield a water supply pipe and a water discharge pipe for a cooling plate associated with the control unit, as well as protecting the high-voltage wire, when the support stand is in the stored position thereof.
