To provide an engine capable of keeping high accuracy of a pulse signal to detect an engine rotating speed and a crank angle.SOLUTION: A pulsar plate 7 is disposed in a transmission device cover 3a for housing a transmission device 3, and includes a fixture 9 for fixing the pulsar plate 7 to a rotating shaft 6, and a disc spring 10 held between the fixture 9 and the pulsar plate 7. The pulsar plate 7 is constituted to be pressed and fixed by elastic restoration force of the disc spring 10. A damper space 10a is formed between the disc spring 10 and the pulsar plate 7, and an engine oil 5 and air are moved between the inside of the transmission device cover 3a and the damper space 10a through a clearance formed on a pressure contact part of the disc spring 10 and the pulsar plate 7 by expansion/contraction of the disc spring 10 by vibration of the pulsar plate 7 in a longitudinal direction of the rotating shaft 6.SELECTED DRAWING: Figure 2 【課題】エンジン回転数やクランク角を検出するパルス信号の精度を高く維持することができるエンジンを提供する。【解決手段】パルサプレート７は、伝動装置３を収容する伝動装置カバー３ａ内に配置され、パルサプレート７を回転軸６に固定する固定具９と、固定具９とパルサプレート７の間に挟みつけられる皿バネ１０を備え、皿バネ１０の弾性復元力でパルサプレート７を押圧固定するように構成され、皿バネ１０とパルサプレート７の間にダンパ空間１０ａが設けられ、回転軸６の軸長方向へのパルサプレート７の振動で皿バネ１０が伸縮することにより、皿バネ１０とパルサプレート７の圧接箇所に生じる隙間を介して、伝動装置カバー３ａ内とダンパ空間１０ａとの相互間で、エンジンオイル５と空気が行き来するように構成されている。【選択図】 図２
