Abstract
【解決手段】噛合いクラッチ23を構成する入力側半体23aと出力側半体23bとの間に、これらの半体同士を噛合いクラッチ23の回転軸方向へ互いに離反させる方向に付勢する付勢部材26を介在させ、駆動源(エンジン14)が正回転したときには、駆動源の動力によって噛合いクラッチをオンにし、駆動源の駆動力が入力側半体23aへ伝達されないときに付勢部材16の付勢力によって噛合いクラッチをオフにする構成とした。

Claims (3)
- 機体にカッターブレードと、走行輪と、この走行輪を駆動する駆動源と、この駆動源と前記走行輪との間の動力伝達系に介在した噛合いクラッチと、この噛合いクラッチを切換えるクラッチ切換え機構とを備えた歩行型芝刈機において、
前記噛合いクラッチは、入力側の噛合い爪を有した入力側半体と、出力側の噛合い爪を有した出力側半体とからなり、
前記クラッチ切換え機構は、
前記入力側半体と前記出力側半体との間に、これらの半体同士を前記噛合いクラッチの回転軸方向へ互いに離反させる方向に付勢する付勢部材を有することにより、前記駆動源が正回転したときには前記駆動源の駆動力が前記入力側半体へ伝達されることにより前記噛合いクラッチをオンにし、前記駆動源の駆動力が前記入力側半体へ伝達されないときには、前記付勢部材の付勢力によって前記入力側半体と前記出力側半体を離間させ、前記噛合いクラッチをオフにする構成であることを特徴とする歩行型芝刈機。 - 前記動力伝達系は、前記走行輪と前記駆動源との間にアクスルシャフトを有し、
前記付勢部材は、前記アクスルシャフトの周囲を取り巻くようにして前記噛合いクラッチの前記両半体の間に介在することを特徴とする請求項1記載の歩行型芝刈機。 - 前記動力伝達系のなかの、前記駆動源と前記噛合いクラッチとの間に、前記駆動源が回転しているときのみクラッチオンとなる回転式クラッチが介在していることを特徴とする請求項1又は請求項2記載の歩行型芝刈機。
