さらに、本発明では、製造コストを低減すると共に、レバー部の必要な剛性・強度を確保することが可能なシフト装置の製造方法を得ることができる。
一対の突出部28は、樹脂材料によってノブカバー本体と一体で形成されるが、別体で形成してもよい。
図示しない金属製の板材をプレス加工によって、開放断面形状を有する部材に成形する。さらに、この部材の外面を樹脂材料で被覆する樹脂モールド成形を、例えば、金型等を用いて行うことにより、簡素な工程で簡便にレバー部12を製造することができる。本実施形態では、このような製造方法を採用することにより、製造コストを低減すると共に、レバー部12の必要な剛性・強度を確保することができる。
図9(a)、(b)に示されるように、レバー部12の軸方向と略直交する方向に延在する突出部28は、ノブインナ部24に形成された矩形状の凹部54と、レバー外周部34に形成された矩形状の凹部56とによって構成された溝部30内に挿入され、突出部28が抜け止めされることにより操作ノブ14の抜け止めを達成することができる。
