A portable power working machine is disclosed, which is capable of effectively minimizing the clogging of the air cleaner, thereby dispensing with frequent maintenance. This portable power working machine comprises an air cleaner () having a base body case () provided with a clean air discharge port () for introducing the air cleaned into an intake port () of a carburetor (), a filter () which is mounted on a filter mounting opening () of base body case () so as to seal it, and a cleaner cover () which is attached onto the filter () so as to cover the filter () and to guide outside air toward the filter (), while giving a predetermined directionality to the outside air. The air cleaner () is also configured to include a suction port () and a suction guiding member () both designed to discharge the dust out of the air cleaner () through a space formed between the filter () and the cleaner cover () as the dust adhered to the outside air side of the filter () is sucked out by taking advantage of a negative pressure to be generated by a fan ().

A power source and a human contacting portion of a portable power tool, with a vibration-proof member and a spacer placed between them, are tightened by fastening and connecting means in the direction approaching each other. The spacer serves to limit compressive power of the vibration proof member which acts between the power source and human contacting portion within effective vibration-proof range of the vibration-proof member by utilizing the fastening and connecting means, This does not cause the vibration absorbing effect of the vibration-proof member to be lost. In addition, there is no need to check the fastening degree achieved by the fastening and connecting means, thus allowing easy attachment of the vibration-proof member thereto. Alternatively, vibration-proof members may be placed between the power source side and the working member side without spacers if the vibration proof members support the power source apart from the working member. To facilitate this construction a universal power transmission, such as a flexible shaft or coupling, is used to transmit rotation power from the power source to the working member in spite of a change in the relative positional relation of the power source to the working member, caused by the vibration-proof member.

A working machine such as a power blower has a blower pipe with a silencer. The blower pipe has an outer pipe and a perforated inner pipe, with a sound absorbing material disposed between the inner and outer pipes. For ease of handling in use of the power blower, the outer pipe has substantially constant diameter. For ease of storage, the pipe is detachable.
