Description
(1)上記した回転ノブは、チェーンソーのオイルキャップに好適に用いられる。チェーンソーは、チェーンソー本体と、ガイドバーと、ソーチェーンと、オイルタンクと、オイルキャップを備える。ガイドバーは、チェーンソー本体に対して進退可能に取り付けられている。オイルタンクには、ソーチェーンやガイドバーに供給する潤滑油が貯留される。オイルキャップは、オイルタンクに回転可能に設けられ、オイルタンクの開口部を閉口する。
ツマミ150が操作位置にある場合、ツマミ150は、ねじりばね152の付勢力によって、ノブ本体166に当接される。この結果、ツマミ150は、操作位置で安定する。これにより、ツマミ150の操作性が向上する。
オイルキャップ42でも同様に、ロック部材58をロック位置から非ロック位置に移動させることによって、ツマミ50のロックが解除され、収容位置から操作位置に移動される。ツマミ50が操作位置にある場合、ツマミ50は、ねじりばね52の付勢力によって、ノブ本体66に当接される。この結果、ツマミ50は、操作位置で安定する。これにより、ツマミ150の操作性が向上する。
オイルキャップ42でも同様に、ツマミ50を操作位置から収容位置に向けて揺動すると、ロック部材58がロック位置から非ロック位置に移動される。ツマミ50が収容位置に移動されると、ロック部材58は、ばね52の付勢力によって非ロック位置からロック位置に移動する。この結果、ツマミ50を収容位置に収容する場合、ロック部材58を操作することなく、ツマミ50を操作位置から収容位置に移動させるだけで、ツマミ50が収容位置で自動的にロックされる。
上記した実施例の固定操作ノブ28の変形例を図面を参照して説明する。
図14は、第1変形例の固定操作ノブ228を示す。図14及び以下では、固定操作ノブ28と同一の構成については、上記の実施例と同一の符号を付すとともに、重複する説明を省略する。
ノブ本体166には、ツマミ450が揺動軸154を介して揺動可能に取り付けられている。揺動軸154は、ねじりばね152に挿通されている。ねじりばね152は、ツマミ450を収容位置から操作位置に向けて付勢している。
ロック部材458は、リング部材180の凹部470と係合する係合部458aを有している。係合部458aは、収容位置から操作位置に向かう方向に沿って、ツマミ450の外側に向けて傾斜している。リング部材180の内周面には、ロック部材458と係合する複数の凹部470が形成されている。凹部470は、リング部材180の周方向に等間隔で形成されている。
