<P>PROBLEM TO BE SOLVED: To provide a cylinder device which enhances workability in assembling to thereby enhance productivity. <P>SOLUTION: In the cylinder device, a piston 12 to which a piston rod 2 is connected is fitted into a cylinder member 3, and the piston rod 2 is energized by a coil spring 27 with a clutch member 24 interposed therebetween. The coil spring 27 is supported by the clutch member 24 and a spring guide 6. Passage area S1 of a passage 6k on the spring guide 6 is defined larger than passage area S2 of a communication passage 14 on the piston 12, whereby channel resistance caused by the spring guide 6 is to be suppressed in assembling. <P>COPYRIGHT: (C)2012,JPO&INPIT |
