摘要： A chain saw 1 has a body 3 in which a stratified scavenging 2-cycle engine 5 for driving a saw chain 21 is laterally housed and a top handle 41 provided above the body 3. In other words, by laterally disposing the engine 5, an air port can be installed upward to a cylinder, and an air quantity adjusting device for feeding scavenging air to the air port and the carburetor can be well housed in the top handle 41. Accordingly, there is no need to separately prepare a space for installing the air quantity adjusting device, so that miniaturization can be achieved.
摘要翻译：链锯1具有主体3，其中用于驱动锯链21的分层扫气式二冲程发动机5横向容纳在主体3中，并且顶部手柄41设置在主体3上方。换句话说，通过横向布置发动机5，通气口可以向上安装到气缸上，并且用于将吹扫空气供给到气口和化油器的气量调节装置可以很好地容纳在顶部手柄41中。因此，不需要单独准备用于安装的空间空气量调节装置，从而可以实现小型化。
