Combustion type power tool facilitating cleaning to internal cleaning target

摘要

A combustion type power tool capable of performing cleaning to a cleaning target from outside of the tool without disassembly of a head cover and a head cap. In the head cap, first and second cleaning passages are formed. The first cleaning passage has one end open to an atmosphere and a closed inner end. The second cleaning passage has one end in communication with the first cleaning passage and another end open to a spark generating portion which is one of the cleaning target in the combustion type power tool. A check valve is disposed in the first cleaning passage for normally closing the one end of the first cleaning passage by a biasing force of a compression coil spring. If a nozzle of a compression type cleaning liquid canister is inserted into the one end of the first cleaning passage and the cleaning liquid is injected, the check valve is opened by the injection pressure, so that cleaning liquid is supplied to the cleaning target through the second cleaning passage.
