Claims (1)
- エンジン(10)のクランク軸(11)に固設されたフライホイール(2)の板面におけるクランク軸(11)を中心とする同一円上に、複数の検出用孔(2a・・)を穿設し、該複数の検出用孔(2a・・)は、等角度間隔に形成されているとともに、その中の一つを欠孔(2b)とし、前記検出用孔(2a)を検出する検出手段(3)と、該検出手段(3)からの検出信号に基づいてエンジン回転数(R)およびピストンの上死点位置を算出する算出手段(4)とを具備し、前記検出用孔(2a)に対向する位置に、前記検出手段(3)を固定するに際して取付位置を決定する位置決め冶具(3a)を具備し、該位置決め冶具(3a)は、一側が検出用孔(2a)と嵌合し、他側が検出手段(3)と嵌合することによって、前記検出手段(3)の取付位置の決定が可能となるように構成し、前記位置決め冶具(3a)の一側を前記欠孔(2b)がピストンの上死点位置にあるときでフライホイール(2)の回転方向と逆方向の位置にある検出用孔(2a)に嵌合させ、他側を検出手段(3)に嵌合させることによって、前記検出手段(3)の取付位置を決定し、該決定した取付位置に検出手段(3)が固定されるように構成したことを特徴とするエンジン回転数検出装置。
