BACKGROUND OF THE INVENTION
The present invention relates to a rear flasher mounting structure for a motorcycle.
[0002]
[Prior art]
The rear flasher of a motorcycle is usually attached to the rear part of the rear fender above the rear wheel. In the case of a configuration to be attached to the rear fender, the rear fender itself is made of resin and has elasticity, and absorbs the vehicle body vibration to suppress the influence of the vehicle body vibration on the rear flasher.
[0003]
On the other hand, in a motorcycle equipped with saddle bags on the left and right sides of the rear rear fender, a rear flasher may be attached to the lower side of the rear end of the saddle bag below the rear fender in terms of structure or design. In this case, the rear flasher is fixed to the vehicle body frame via a connecting stay or the like.
[0004]
[Problems to be solved by the invention]
However, if the rear flasher is fixed to the vehicle body frame via a connecting stay made of a metal material or the like, the influence of vibration or the like is large, and there is a risk of disconnection or filament breakage. In addition, if the rear flasher is attached simply through a flexible elastic material, the flasher will not be stably supported and will hang down, or vibrations in the vertical and horizontal directions and the front and rear directions will not be properly absorbed, and the flasher will In order to avoid large fluctuations and interference with the saddle bag or the like, it is necessary to make a large gap between them, and thus the position of the flasher becomes inappropriate and the visibility is impaired.
[0005]
The present invention takes the above-described conventional technology into consideration, and effectively absorbs vibrations of the vehicle body, and stably supports the rear flasher on the vehicle body side without drooping or fluttering, thereby bringing the flasher to an appropriate position. An object is to provide a rear flasher mounting structure for a motorcycle that can be installed and can ensure visibility.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, in the present invention, an elastic stay is cantilevered on the vehicle body side, a rear flasher is attached to the end of the elastic stay, and the elastic stay is covered with an elastic cover. A motorcycle characterized in that a cover is supported by a tongue made of a rigid material fixed to the vehicle body side, and an elastic protrusion is provided on the vehicle body side to contact the rear flasher from a direction opposite to the direction in which the tongue material is supported. A rear flasher mounting structure is provided.
[0007]
According to this configuration, the rear flasher is provided at the end of the elastic stay fixed to the vehicle body side, and the elastic stay is rigid while having an appropriate elasticity from the vehicle body side to the tongue material via the elastic cover. Therefore, the rear flasher is reliably supported at a fixed position without hanging down. In addition, the rear flasher is elastically restrained by being substantially sandwiched between the tongue material by the elastic protrusions from the vehicle body side opposite to the tongue material support direction, so that the flapping is suppressed and the elastic stay end is stable. Held in the department.
[0008]
In a preferred configuration example, saddle bags are attached to the left and right sides of the rear wheel via saddle bag mounting stays, brackets integrated with the tongue material are fixed to the rear end of each saddle bag mounting stay, and the elastic members are attached to the brackets. The stay is attached and the tongue is inserted into the lower peripheral wall of the elastic cover, and the elastic protrusion is provided on the lower surface of the rear end of the saddle bag or on the saddle bag mounting stay.
[0009]
According to this configuration, in a motorcycle equipped with a saddle bag, the saddle bag mounting stay is used to provide the bracket for attaching the elastic stay in a compact manner, and the elastic stay is lowered by the tongue inserted under the elastic cover. The saddle bag is provided with an elastic protrusion that is supported from the side and abuts against the rear flasher, so that vibration and fluttering of the rear flasher can be effectively suppressed from the upper side.
[0010]
In a further preferred configuration example, the elastic cover is formed with a hole for reducing the restraining force on the elastic stay.
[0011]
According to this configuration, by providing a hole in the elastic cover, a decrease in flexibility due to the elastic stay being put on the elastic stay is suppressed, and an appropriate elastic force is applied to the rear flasher to absorb vibrations in each direction. The rear flasher can be held.
