にアースをせしめる手段が採られている。Generally, in portable working machines that generate large vibrations, such as chainsaws, a vibration isolating material is interposed between the engine and the parts that support the engine, such as the bundle frame, to prevent vibrations from being transmitted to the hands of the operator. However, since this vibration isolating material is made of rubber or other electrically insulating materials, it does not have electrical conductivity, so electricity that leaks into the parts that support the engine and is transmitted to the hands of the worker. Therefore, a method is adopted in which both ends of a conductive wire are attached between the engine and the member supporting the engine to ground the engine to prevent electricity leaking to the member supporting the engine.
したがって、エンジンを支持する部材とエンジンの組立
て時には、導電線の接触不良を起したり、組み忘れや紛
失を招いたりするなどの問題がある。Therefore, when assembling the engine with a member that supports the engine, there are problems such as poor contact between the conductive wires, forgetting to assemble them, or loss of the conductive wires.

、紛失するのを解消するにはまだ問題が残されている。Some attempts have been made to solve this poor contact by installing a spring made of a conductive material between the engine and the engine supporting member located near the non-conductive vibration isolator. Even with this structure, there is still a problem in solving the problem of forgetting to assemble or losing the spring when disassembling and reassembling the chainsaw.
