Abstract: In a vehicle body-protecting device for a two-wheeled motor vehicle, in which a pair of left and right guard members are mounted to a vehicle body frame assembly to overhang laterally outwards, so that when the two-wheeled motor vehicle is turned sideways, said guard members are allowed to be grounded, whereby the grounding of an outer surface of a vehicle body is diminished, each of the guard members is formed by connecting a ground element which is grounded upon the turning-sideways of the two-wheeled motor vehicle to a mounting base secured to the vehicle body frame assembly through an elastic element for swinging movement. Thus, it is possible to eliminate the need for the special strengthening of the vehicle body frame assembly in such a manner that a shock due to the turning-sideways of the two-wheeled motor vehicle can be received on the vehicle body frame assembly, while being buffered.

Abstract: In a rear luggage-carrier device for a motorcycle, in which a rear carrier disposed in the rear of a pillion portion for a tandem rider is supported by a pair of stays secured to left and right rear portions of a vehicle body, a backrest is supported on the stays so that it can be turned between an upright position and a housed position. In the upright position, the backrest is located above a rear end of the pillion portion such that it can contact from behind the waist of a tandem rider on the pillion portion. In the housed position, the backrest has been turned rearward from above a rear end of the pillion portion and housed in a front portion of the rear carrier so that luggage can be placed on the backrest.

Abstract: In a vehicle body-protecting device for a two-wheeled motor vehicle, in which a pair of left and right guard members (G) are mounted to a vehicle body frame assembly (F) to overhang laterally outwards, so that when the two-wheeled motor vehicle (M) is turned sideways, said guard members (G) are allowed to be grounded, whereby the grounding of an outer surface of a vehicle body is diminished, each of the guard members (G) is formed by connecting a ground element (24) which is grounded upon the turning-sideways of the two-wheeled motor vehicle (M) to a mounting base (20) secured to the vehicle body frame assembly (F) through an elastic element (23) for swinging movement. Thus, it is possible to eliminate the need for the special strengthening of the vehicle body frame assembly in such a manner that a shock due to the turning-sideways of the two-wheeled motor vehicle can be received on the vehicle body frame assembly, while being buffered.
