Description
加えてOリングは、カップリング部材とクランク軸とに密着するように弾性変形するだけで、カップリング部材の回転時やクランク軸の回転時には、Oリングに対して回転方向で潰す力が加わることがない。よって、Oリングが潰されることでちぎれることはなくなる結果、Oリングの耐久性を向上させることが可能になる。
また、Oリングを、凹部の開口側の端面と、凸部の基端部側の端面との間に挟んで両端面に密着させ易くなる。したがって両端面間で、カップリング部材の回転方向やクランク軸の回転方向における抵抗を容易に増加させることができる。
さらに、Oリングを配置するスペースを、カップリング部材とクランク軸との間に新たに設ける必要がない。しかも、Oリングの採用により、安価に形成することが可能になる。
請求項2の発明によれば、カップリング部材の端面に凹部を形成することで、カップリング部材の端部に、断面が凸状となる2つの部位を設けることができる。したがって、2つの部位の重量でカップリング部材の重量を、一つの凸部を備えるクランク軸の重量よりも重くすることができる。よって、カップリング部材の強度を、該カップリング部材に従動するクランク軸の強度よりも強くすることができる。
本実施形態の往復回転式電動工具1では、Oリング17は、カップリング部材10とクランク軸12との間で出力軸9の軸線と同一軸線方向Xに弾性変形し、カップリング部材10とクランク軸12とに密着可能となる。したがって、Oリング17によりカップリング部材10の回転方向やクランク軸12の回転方向における抵抗が増加する結果、回転方向でカップリング部材10とクランク軸12との一体性が高まる。これにより、カップリング部材10とクランク軸12との打ち合いに起因した異音の発生を抑制できる。
加えてOリング17は、カップリング部材10とクランク軸12とに密着するように弾性変形するだけで、カップリング部材10の回転時やクランク軸12の回転時には、Oリング17に対して回転方向で該Oリング17を潰す力が加わることがない。よって、Oリング17が潰されることでちぎれることはなくなる結果、Oリング17の耐久性を向上させることができる。
