Abstract:
1. A portable working machine comprising: a motive power source for producing a rotational motion; a cutting blade mounted to undergo linear reciprocating motion; a reduction mechanism for reducing a speed of the rotational motion produced by the motive power source; a motion conversion mechanism for converting the rotational motion reduced in speed by the reduction mechanism into a linear reciprocating motion of the cutting blade; a case accommodating therein the reduction mechanism and the motion conversion mechanism and having a lower surface; a cover member covering the lower surface of the case, the cover member having a first part connected to the lower surface of the case and a second part contiguous to the first part and extending to underlie a part of the lower surface of the case located below the reduction mechanism with a space defined between the part of the lower surface of the case and the second part of the cover member, the cover member being in the form of a cantilever with the first part connected to the lower surface of the case and the second part hanging free in a vertically spaced-apart relation to the lower surface of the case; and an impact-absorbing member disposed in the space between the part of the lower surface of the case and the second part of the cover member.
