PURPOSE:To exhibit high vibration proof effect thus to secure the cylinder cover reliably by providing cylinder covers while contacting against the outer end of cooling fin at the opposite end sections of cylinder body. CONSTITUTION:Plural cooling fins 4 are projected in multi-stages from the outside face of cylinder body 1. Cylinder covers 6 are provided while contacting against the outer end of the cooling fin 4 at the opposite sides of the cylinder body 1. The opposite end sections of both cylinder covers 6 are coupled through a bolt 7 and nuts 8. Consequently, high vibration proof effect is exhibited to secure the cylinder cover firmly. |
