摘要： An engine blower includes: an engine integrated with a volute for driving a fan; a ventilation tube communicated with the volute; and a handle mounted to the ventilation tube. In the engine blower, the handle has a pair of cases that are assembled with each other, and a conductive resin layer is formed on a surface of a grip of the handle. The resin layer is integrated with gates exposed within the handle. A conductive spring having a coil compressed in a direction in which the cases are assembled with each other and a cable that is electrically coupled with the engine are disposed within the handle. The gate of the resin layer is brought into contact with the coil of the spring and is electrically coupled with the cable via the spring.

摘要： A portable-blower duct has a bendable portion whose inner peripheral surface is a cylindrical surface without any protrusions or recesses in a normal state or in an expanded state, that is, unless it is greatly curved. With this construction, no turbulence is generated in air passing through a tube, thereby making it possible to suppress pressure loss. Thus, the flow velocity of air guided through the duct is not reduced, thereby suppressing a deterioration in air blowing efficiency. Even when the tube is curved, the outer side of the curved portion is expanded, and the corresponding portion of the inner peripheral surface remains a smooth surface, thus making it possible to minimize the air pressure loss.
摘要翻译：便携式鼓风机管道具有可弯曲部分，其内周表面是圆柱形表面，在正常状态或膨胀状态下没有任何突出或凹陷，即除非它大大弯曲。通过这种结构，在通过管的空气中不产生湍流，从而可以抑制压力损失。因此，通过导管引导的空气的流速不降低，从而抑制送风效率的劣化。即使管弯曲，弯曲部的外侧膨胀，内周面的对应部分保持光滑的表面，从而可以使空气压力损失最小化。

摘要： A portable-blower duct has a bendable portion (22) whose inner peripheral surface (221A) is a cylindrical surface without any protrusions or recesses in a normal state or in an expanded state, that is, unless it is greatly curved. With this construction, no turbulence is generated in air passing through a tube (221), thereby making it possible to suppress pressure loss. Thus, the flow velocity of air guided through the duct is not reduced, thereby suppressing a deterioration in air blowing efficiency. Even when the tube (221) is curved, the outer side of the curved portion is expanded, and the corresponding portion of the inner peripheral surface remains a smooth surface, thus making it possible to minimize the air pressure loss.
