Description
本願は、2013年11月1日に、日本に出願された特願2013-228333号に基づき優先権を主張し、その内容をここに援用する。
第1の実施形態のリザーバを図面に基づいて説明する。本実施形態のリザーバ11は、四輪自動車等の車両に搭載される。リザーバ11は、図1に示すようにマスタシリンダ12に取り付けられて車載される。ここで、図1に示す姿勢は、リザーバ11およびマスタシリンダ12の車載状態での姿勢である。リザーバ11およびマスタシリンダ12は、図1における左側が車両の前進時の前側となるようにして車載される。なお、以下の説明における前後左右は車両前進時の前後左右である。
これらの前側載置底部38および後側載置底部39は、それぞれの下面において、同一平面に配置された取付ボス部14,15の上面に載置されることから、それぞれの下面が同一平面に配置され、水平に対して若干前上がりに傾斜している。前側載置底部38の中間位置には、前側載置底部38に対して垂直下方に突出する取付突起部42が形成されている。後側載置底部39の中間位置にも、後側載置底部39に対して垂直下方に突出する取付突起部43が形成されている。
先端壁部120は、仕切壁100に対して前後方向に間隔をあけている。
つまり、連通路231内に導出される液体の量が多いと、キャップ19とリザーバ本体18との隙間から液体が滲み出すことがあるが、このような状態となることを抑制できる。
つぎに、第2の実施形態を図9に基づいて説明する。図9は、図3のC-C断面に相当する断面図となっている。上記第1の実施形態においては、面部222を、前後方向の同位置で左右方向位置にかかわらず高さ位置が一定するように傾斜して形成している。この第2の実施形態においては、面部222に対応する面部322を、前後方向のみならず、左右方向においても傾斜して形成している。
つぎに、第3の実施形態を図10及び図11に基づいて説明する。第3の実施形態では、リザーバ本体418が、第1の実施形態のリザーバ本体18に対し一部変更したものとなっており、具体的には、その上部構成体420が、上部構成体20に対し一部変更したものとなっている。上記第1の実施形態においては、面部222を形成するために傾斜板部211を主板部210よりも下方に凹む凹部221により形成している。この第3の実施形態においては、主板部410(主板部210に対応)よりも上方に突出する段部401を形成し、この段部401に、傾斜板部411(傾斜板部211に対応)、凹部421(凹部221に対応)及び連通路天井板部410A(連通路天井板部210Aに対応)を形成するようにしている。そして、傾斜板部411の内部に面部222に対応する面部422(面部222に対応)が形成されている。傾斜板部411、凹部421及び面部422は、図11に示すように、第1の実施形態の傾斜板部211、凹部221及び面部222と同様の構造を有している。そして、凹部421は、連通路天井板部410Aよりも凹んで形成されている。しかしながら、凹部421は、主板部410よりも上方に形成されている。
