摘要: A power equipment includes an exhaust pipe member disposed near a muffler, the exhaust pipe member having an exhaust gas passage portion which communicates with the outlet of the muffler and an outlet passage portion whose downstream end has a downstream outlet end communicating with the atmosphere. The power equipment further includes a tubular member for introducing a portion of compressed air flow from a blower, and a gap is formed between an opening formed in the exhaust pipe member and an adjacent end of the tubular member. A guide tube member defines the opening in the interior of the upstream end of the exhaust pipe member.
