在（a)中，鉸鏈外殼153的上部突出部172、172及 下部突出部1 7 3、1 7 3，是處於抵接於車體外殼4 6的缺口 部1 5 4的緣部的狀態。此時，U字型彈簧1 7 1，是處於將 U字型的兩個端部打開而撓曲的狀態，以該撓曲所產生的 彈性力來將鉸鏈外殻1 5 3按壓在缺口部1 5 4的緣部。 在（b )中，鉸鏈外殼1 5 3與車體外殼46的間隙d (參照（a)圖）是設定成下部較上部更大，將雙人座墊 2 3開始開啓，當座墊鉸鏈5 1的座墊側鉸鏈7 8如箭頭所 示些許地從假想線的位置擺動到實線的位置時，U字型彈 簧1 7 1的撓曲會變小’彈性會變小’鉸鏈外殼1 5 3的上部 突出部1 7 2、1 7 2會保持被按壓在缺口部1 5 4的緣部，將 缺口部154的緣部與上部突出部172、172的接觸部爲中 心，讓鉸鏈外殼1 5 3的下部如箭頭所示稍微開啓，下部突 出部1 7 3、1 7 3會從缺口部1 5 4的緣部分離。 在（c )中，座墊側鉸鏈7 8更加擺動的話，u字型彈 -20- (17) (17)200401727 簧1 7 1的撓曲幾乎沒有，鉸鏈外殻1 5 3會與座墊側鉸鏈 78 —起擺動，上部突出部I72、172及下部突出部173、 1 7 3會一起從缺口部1 5 4的緣部分離。 鉸鏈外殼1 5 3與車體外殼46的間隙是設定成下部較 上部更大，藉由讓鉸鏈外殼1 5 3從缺口部1 5 4的緣部先離 開下部突出部1 7 3、1 7 3側，則能夠以不使鉸鏈外殼1 5 3 的下部干涉到，爲了使車體外殼46與鉸鏈外殼153的個 別的表面連續而設置在車體外殻4 6的外殻段部1 8 1的方 式，來使鉸鏈外殼1 5 3移動。 如上述的第2圖、第11圖及第13圖所說明，本發明 的第1特徵，是將駕駛者用座墊23A與共乘者用座墊23B 形成爲一體，且將其作成經由設置在雙人座墊2 3側邊的 座墊鉸鏈5 1而可自由開閉的機車1 〇 (參照第1圖），其 特徵爲：將座墊鉸鏈5 1安裝成讓其座墊側鉸鏈7 8跨越駕 駛者用座墊23A與共乘者用座墊23B。 以往的大型座墊，爲了防止座墊撓曲而被偷盜，是在 兩個位置安裝有將座墊卡合於車體側的座墊扣，在本發明 中，由於座墊鉸鏈5 1的座墊側鉸鏈7 8是跨越駕駛者用座 墊23A與共乘者用座墊23B，所以能夠以座墊鉸鏈51的 座墊側鉸鏈78來補強駕駛者用座墊23A與共乘者用座墊 23 B的連結部，可以提高座墊23的剛性，。如果提高雙 人座墊23的剛性的話，雙人座墊23，即使想要以不合理 的方式開啓也不容易撓曲，可以提高防盜效果。而能夠將 座墊扣5 2減少爲一個。 -21 - (18) (18)200401727 由於是以座墊鉸鏈5 1來進行雙人座墊2 3的補強，所 以不需要加上用來補強雙人座墊2 3的特別零件。 如以上所述，能夠減少機車1 〇的成本。 本發明的第二特徵，是在雙人座墊23的更下方配置 車體外殼46，在該車體外殼46內設置置物箱22，在車體 外殼4 6形成允許座墊鉸鏈5 1的朝向車體側邊的擺動的缺 口部1 5 4，並且在車體外殼4 6內的置物箱2 2的外側且下 方設置作爲座墊鉸鏈5

方，與將鉸鏈軸7 7設置在置物箱2 2的開口部1 6 8附近的 方式相比，能夠大幅度地開啓雙人座墊23，能夠便利地 對於置物箱22進行東西的置入及拿出。能夠將開口部 1 68整個面利用爲置物箱22，而能夠收容較大的東西或更 多的東西，例如可同時收容共乘者用安全帽與共乘者用安 全帽。。 即使將雙人座墊2 3大幅度地開啓，藉由以鉸鏈外殼 1 5 3覆蓋缺口部1 5 4，則能夠防止座墊鉸鏈5 1露出於外 部，所以可以提昇外觀性。 -22- (19) (19)200401727 本發明的第三特徵，將鉸鏈外殻1 5 3經由U字形彈 簧1 7 1安裝於座墊側鉸鏈7 8，當鉸鏈外殼〗5 3與車體外 殼46抵接時，兩者的間隙是設定成下部較上部更大，當 將座墊鉸鏈5 1開啓時，鉸鏈外殼1 5 3的下部是較上部先 離開車體外殼46。 當將雙人座墊23開閉時，能夠順暢地將鉸鏈外殻 1 5 3離開或抵接於缺口部〗5 4的緣部，而能夠良好地進行 鉸鏈外殼1 5 3的開閉。 第1 4圖是本發明的置物箱的立體圖，是顯示將凹部 184 —體成形於置物箱22的凸緣部83的前部。 凹部1 84是與後述的雙人座墊側的凸部卡合而防止雙 人座墊不合理的關閉的部份。 第15圖是顯示本發明的雙人座墊的底面的底面圖， 在雙人座墊23的底板54的前部，是一體成形有朝向車寬 方向內側突出的凸部1 8 6。1 8 7、1 8 8是用來安裝座墊鉸鏈 5 1的抵接座墊鉸鏈5 1的安裝端部9 8、9 8 (參照第6圖） 的座墊安裝部，1 9 1是用來安裝座墊鉸鏈5 1的抵接座墊 鉸鏈5 1的座墊安裝片9 3 (參照第6圖）的座墊側安裝 部，1 93 · · · ( · · •表示複數個。以下相同。）是安 裝孔，194是用來安裝座墊鉤53的座墊鉤安裝部，196、 196是安裝孔。 第16圖（a) 、（b)是用來說明置物箱與雙人座墊 的卡合的剖面圖，（a )是顯示卡合狀態的剖面圖，（b ) 是顯示當將雙人座墊關閉時的作用的剖面圖。 -23- (20) 200401727 在（a )中，置物箱22的凹部1 84具備有用來支承 人座墊23的凸部1 86的傾斜面1 84A。 雙人座墊23的凸部186，是具備有伸入進置物箱 的傾斜面184A下的圓弧狀的卡合面186A。 圖中的2 0 0是上述卡合面1 8 6 A的圓弧的中心也就 卡合面1 8 6 A的旋轉中心的旋轉中心點。該旋轉中心 2〇〇，當將置物箱22的凹部184與雙人座墊23的凸 1 8 6的卡合部份當作卡合部2 0 1的話，是第8圖（a ) (b )所示的鉸鏈軸7 7的延長線1 1 6與平行於通過該 合部2 0 1的紙面的平面相交的點。 如第8圖（a ) 、 （ b )所示，在本發明中，是以從 面來看朝前下方且在平面來看鉸鏈軸77的前部是較後 更位於車體內側的方式，來使座墊鉸鏈5 1的鉸鏈軸7 7 斜’在第1 6圖（a )中，是將旋轉中心點2 0 0相對於卡 部201配置在下方。 接下來說明以上所述的置物箱2 2的凹部1 8 4與雙 座墊2 3的凸部1 8 6的卡合的作用。 在（b )中’由雙人座墊2 3開啓的狀態，開始關閉 話，雙人座墊23會以旋轉中心點2〇〇爲中心旋轉，伴 者讓凸邰1 8 6的卡合面1 8 6 A伸入於置物箱2 2的凹部1 的傾斜面1 84 A ’如（a )所不，凸部1 g 6會卡合在凹 1 8 4。在該狀態下，例如，即使以不合理的方式要將雙 座墊23的前部開啓，也能藉由卡合部2〇1來阻止。 回到（a )，例如，將凸部1 80的旋轉中心點作 雙 22 是 點 部 卡 側 部 傾 合 人 的 隨 84 部 人 爲 -24- (21) (21)200401727 2 00A，將其配置在卡合部201的正下方的話，當要以不 合理的方式將雙人座墊2 3的前部打開而力量朝上方作用 時，在旋轉中心點2 0 0 A的周圍不會產生使雙人座墊2 3 旋轉的力矩。旋轉中心點200，由於是更接近上述旋轉中 心點2 0 0 A的點，所以可以更減少使雙人座墊2 3旋轉的 力矩，以卡合部2 0 1能夠堅固地將凸部1 8 6卡合在凹部 184° 圖中的2 0 0 β是顯示，不使鉸鏈軸朝前下方傾斜，讓 鉸鏈軸的前部較後部更位於車體內側，在正面來看是配置 在置物箱22的開口部1 68的側邊的旋轉中心點。 即使以該旋轉中心點2 0 0 Β爲中心將雙人座墊關閉， 在雙人座墊23側所設置的凸部只要大致朝上下方向移 動，就不能卡合於設置在置物箱側的凹部內。 在第14圖，雖然是將凹部丨84成形在置物箱22的凸 緣部8 3的前部，而並不限於此，也可以在置物箱2 2的側 邰的凸緣部8 3設置凹部，而與雙人座墊2 3側所設置的凸 部卡合。而也可以在雙人座墊 2 3側設置凹部，在置物箱 22側設置凸部。 第1 7圖是用來說明本發明的置物箱內的分隔部的立 體圖，是顯示設置有插入在置物箱22內能夠變更位置的 一片分隔板2 1 1。省略了舖設於置物箱22內的地毯部 (後面會詳細敘述）。 分隔板2 1 1，是可更換到：設置在置物箱2 2內的前 部的前部分隔板插入部2 1
