PROBLEM TO BE SOLVED: To provide a portable work machine which reliably reduces vibration while suppressing degradation of operability, with a simple structure, without incurring an increase in the number of components nor an increase in assembly man-hours.SOLUTION: A casing 10 on which a work blade (a saw chain 14) and a power source (an engine 11) are mounted, and a frame part 20 on which handles (a front handle 21 and a rear handle 22) to be gripped by an operator are disposed, are coupled to each other using elastic members (a first coil spring 23a, a second coil spring 24a, etc.) to which elastic bodies (a first elastic body 23b and a second elastic body 24b) are joined for regulating relative displacement of the casing 10 and the frame part 20, and thereby vibration that is transmitted from the power source (the engine 11) to a frame part 20 side is reduced by the elastic members (the first coil spring, the second coil spring 24a, etc.) and the relative displacement of the casing 10 and the frame part 20 is regulated by the elastic bodies (the first elastic body 23b and the second elastic body 24b). |
