Description
同構成によれば、例えば平板部の上面から収容部内への液体の浸入が抑制される。よって、駆動装置が被水してしまうことを低減することができる。特に、収容部の周囲の周壁は、金属材を板金加工することで製造することは難しいが、ステップ部材が樹脂材にて成形されるため、ステップ部材に容易に一体成形することができる。
同構成によれば、特に固定するためのねじ等の締結部材が必要とされない。尚、板金部材を圧入固定するための板金被圧入部は、金属材を板金加工することで製造することは難しいが、ステップ部材が樹脂材にて成形されるため、ステップ部材に容易に一体成形することができる。
同構成によれば、部品点数の増加を避けながら、ベルトの下方への脱落を低減することができる。
車両には、図示しない車両スライドドアと隣接して、図1に示すステップユニット1が設けられている。図1および2において、「外側」は車両幅方向における車両室の外側を指し、「内側」は車両幅方向における車両室の内側を指す。
(1)駆動装置2は、搭乗者が足を乗せる平板部4の上面4aより下方に底5aが形成された収容部5内に、その一部が収容された状態で固定される。よって、平板部4の上面4aからの駆動装置2の上方への突出を抑えることができる。その結果、車両室内の低床化を図ることが可能である。しかも、ステップ部材3は、一般的に金属材を板金加工してなるのとは異なり、樹脂材にて成形されるため、製造されるものの形状の自由度が増し、前記収容部5の底5aを平板部4の上面4aより大幅に下方に容易に設定することができる。よって、平板部4の上面4aからの駆動装置2の上方への突出を容易且つ大幅に抑えることが可能となる。
・上記実施の形態では、ステップ部材3の下面には、ベルト13の位置を規制すべく立設する規制部15が一体成形され、規制部15のみにてベルト13の位置を規制するとしたが、これに限定されず、例えば、図10~図12に示すように、規制部41のベルト13との摺接面に、板金部材42を固定してもよい。
・軸支可能な軸支持部として、非環状軸支持部16を成形せずに、ブラケット等の別部材を用いてプーリー11を軸支させてもよい。軸支持部は、ステップ部材3に一体成形されつつプーリー11を係着可能且つ軸支可能であれば、前記開口部16aを有した非環状軸支持部16以外の構成のものに変更してもよい。即ち、緊張状態で設けられるベルト13から受ける軸に直交な方向の力によってプーリー11の脱落を防止する機能を備えていない軸支持部でもよい。
