Description

【０００１】
【発明の属する技術分野】
本発明は、自動二輪車のリヤクッションユニット取付構造に関する。
【０００２】
【従来の技術】
自動二輪車のリヤクッションユニット取付構造として、クッションユニットの上端部をカバーで覆ったものが知られている（例えば、特許文献１参照。）。
【０００３】
【特許文献１】
特開平５−８５４４３号公報（第２頁、図１、図２）
【０００４】
特許文献１の図１を以下の図６で説明し、図２を以下の図７で説明する。なお、符号は振り直した。
図６は従来の自動二輪車のリヤクッションユニット取付構造を示す側面図であり、フレーム４４１の下部に後フォーク４４２を上下スイング自在に取付け、この後フォーク４４２の後端部に後輪４４３を取付け、後フォーク４４２とフレーム４４１の後部上部とにクッションユニット４４４を渡し、クッションユニット４４４のフレーム４４１への取付部をカバー４４５で覆った自動二輪車が記載されている。
【０００５】
図７は図６のＡ−Ａ線断面図であり、シート４４６の左右端より車体側方へ突出した左右のクッションユニット４４４，４４４の各上端部をカバー４４５で覆ったことを示す。
【０００６】
【発明が解決しようとする課題】
カバー４４５は、乗員の脚部への当たりを和らげるためにクッションユニット４４４の上端部のみを覆う専用部品であり、その為にコスト増となる。自動二輪車に装備する部品を利用してクッションユニット４４４の上端部を覆うようにすれば、部品数の増加を防ぐことができ、コストアップが抑えられる。
【０００７】
また、クッションユニット４４４のメンテナンスのためにクッションユニット４４４を着脱する場合、左右のカバー４４５を外し、シート４４６も外すことになれば、作業工数が多くなり、メンテナンス性の点では課題が残る。
【０００８】
そこで、本発明の目的は、自動二輪車のリヤクッションユニット取付構造を改良することで、乗員の脚部への当たりを和らげつつ、部品数の増加を防止することでコストアップを抑え且つメンテナンス性を向上させることにある。
【０００９】
【課題を解決するための手段】
上記目的を達成するために請求項１は、後輪の緩衝作用を行うリヤクッションユニットの上端を車体後部側面に取付けた自動二輪車において、車体後部に、リヤクッションユニットに設けた上端取付部の側方を覆う第１カバーを設け、この第１カバーに、上端取付部を車体側に取付けるときに車体側方から工具を挿入する工具挿入用の開口部を設け、この開口部の側方を第２カバーで覆い、第１カバーにおける開口部の近傍の下端部に、第２カバーの下端部を取付け固定したことを特徴とする。
【００１０】
リヤクッションユニットの上端取付部を第１カバー及び第２カバーで覆うことで、同乗者の脚部がリヤクッションユニットの上端取付部に当たるのを防ぐことができる。
【００１１】
また、第２カバーを外すだけで、第１カバーを外さなくても開口部から工具を挿入して車体側に上端取付部を取付ける締結部材を緩め、リヤクッションユニットの脱着が行えるのでメンテナンス性を向上させることができる。
更に、第１カバーと第２カバーとの取付部が目立たず、外観性を向上させることができる。
【００１２】
請求項２は、第１カバーを、車体後部側方を覆うリヤカウルとし、第２カバーを、車体中央部側方を覆うサイドカバーとしたことを特徴とする。
【００１３】
リヤカウルとサイドカバーとでリヤクッションユニットの上端取付部を覆うため、リヤクッションユニットの上端取付部を覆うカバーを特別に設ける必要がなく、部品数の増加を防止することができ、コストアップを抑えることができる。
【００１４】
請求項３は、第１カバーと第２カバーとの合わせ部から、第２カバー側に突出して形成されるサブカウル部を第１カバーに一体に設けるとともに、サブカウル部に開口部を設けたことを特徴とする。
【００１５】
請求項４は、車両前後方向で開口部を挟むように、第１カバーにおける開口部の近傍の下端部と、第１カバー及び第２カバー同士を連結するために第１カバーに設けた係止部とを配置したことを特徴とする。

BACKGROUND OF THE INVENTION
The present invention relates to a rear cushion unit mounting structure for a motorcycle.
[0002]
[Prior art]
As a rear cushion unit mounting structure for a motorcycle, a structure in which an upper end portion of a cushion unit is covered with a cover is known (for example, see Patent Document 1).
[0003]
[Patent Document 1]
JP-A-5-85443 (2nd page, FIG. 1 and FIG. 2)
[0004]
FIG. 1 of Patent Document 1 will be described with reference to FIG. 6 below, and FIG. 2 will be described with reference to FIG. In addition, the code | symbol was reassigned.
FIG. 6 is a side view showing a structure for attaching a rear cushion unit of a conventional motorcycle. A rear fork 442 is attached to a lower part of a frame 441 so as to be swingable up and down, and a rear wheel 443 is attached to a rear end portion of the rear fork 442. A motorcycle is described in which a cushion unit 444 is passed between a rear fork 442 and a rear upper portion of a frame 441, and a mounting portion of the cushion unit 444 to the frame 441 is covered with a cover 445.
[0005]
FIG. 7 is a cross-sectional view taken along line AA in FIG. 6 and shows that the upper ends of the left and right cushion units 444 and 444 protruding from the left and right ends of the seat 446 to the vehicle body side are covered with the cover 445.
[0006]
[Problems to be solved by the invention]
The cover 445 is a dedicated part that covers only the upper end portion of the cushion unit 444 in order to reduce the contact of the occupant with the leg portion, which increases the cost. If the upper end portion of the cushion unit 444 is covered using the parts equipped in the motorcycle, the increase in the number of parts can be prevented and the cost increase can be suppressed.
[0007]
Further, when the cushion unit 444 is attached or detached for maintenance of the cushion unit 444, if the left and right covers 445 are removed and the seat 446 is also removed, the number of work steps increases, and there remains a problem in terms of maintainability.
[0008]
Accordingly, an object of the present invention is to improve the rear cushion unit mounting structure of a motorcycle, thereby reducing the increase in the number of parts and reducing maintenance while reducing the number of parts while reducing the hitting of the occupant's legs. It is to improve.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, a first aspect of the present invention provides a motorcycle in which the upper end of a rear cushion unit that cushions the rear wheel is mounted on the side surface of the rear part of the vehicle body. A first cover is provided to cover the side, and a tool insertion opening for inserting a tool from the side of the vehicle body when the upper end mounting portion is attached to the vehicle body side is provided on the first cover. not covered by the second cover, the lower end in the vicinity of the openings in the first cover, and wherein the fixed attachment of the lower end portion of the second cover.
[0010]
By covering the upper end mounting portion of the rear cushion unit with the first cover and the second cover, it is possible to prevent the passenger's leg from hitting the upper end mounting portion of the rear cushion unit.
[0011]
In addition, by simply removing the second cover, a tool can be inserted from the opening without removing the first cover, and the fastening member for attaching the upper end mounting portion to the vehicle body side can be loosened, and the rear cushion unit can be attached and detached. Can be improved.
Furthermore, the attachment part of a 1st cover and a 2nd cover is not conspicuous, and an external appearance property can be improved.
[0012]
Claim 2, the first cover, and a rear cowl for covering a vehicle body rear side, the second cover, you characterized in that a side cover for covering the vehicle body center portion side.
[0013]
Since the rear cowl and the side cover cover the upper end mounting part of the rear cushion unit, there is no need to provide a special cover to cover the upper end mounting part of the rear cushion unit, which can prevent an increase in the number of parts and suppress the cost increase. be able to.
[0014]
According to a third aspect of the present invention, a sub cowl portion formed so as to protrude from the mating portion of the first cover and the second cover toward the second cover side is provided integrally with the first cover, and an opening portion is provided in the sub cowl portion. Features.
[0015]
According to a fourth aspect of the present invention, there is provided a latch provided on the first cover so as to connect the lower end of the first cover near the opening and the first cover and the second cover so as to sandwich the opening in the vehicle front-rear direction. The portion is arranged.
