摘要： Provided is a handheld electric vacuum capable of improving the operability and workability while reducing the likelihood of the structure becoming more complicated or larger by optimizing the layout configuration around a handle, including a blower fan, a casing, and a battery. The blower fan is inclined forwardly along a bending portion and disposed on the base end side of the bending portion provided at the base end of the pipe. In addition, an opposing portion (vertical side portion) of the handle incorporating the battery, facing the blower fan is inclined (inclined backwardly) oppositely to the blower fan. The upper length (near a grip portion) of a space of the handle formed on the base end side of the blower fan is greater than the lower length thereof.

摘要： To provide an exterior body to attach to an engine body, where the exterior body is not limited to where it may be installed, is safe and has excellent dust proofing capability. An engine exterior body (2) is provided with a frame body (20) configured to attach to an engine body (1); a shaft part (21) projecting from the surface of the frame body (20); and a rotator body (22) including a hole part (22a) loosely fitted and retained on the shaft part (21). The rotator body (22) rotates about the shaft part (21) by way of the vibrations transmitted to the shaft part (21) when engine body operates without receiving power from the engine body (1).

摘要： The present invention provides a blower with reduced noise. The blower comprises a blower main body incorporating a centrifugal fan. The blower main body is configured to suck air from both sides of the blower main body by rotation of the centrifugal fan. The centrifugal fan includes a support plate having a rotation center and a plurality of blades provided on each of a first surface and a second surface of the support plate. A position of at least part of the plurality of blades on the first surface and a position of at least part of the plurality of blades on the second surface are misaligned in a circumferential direction, and/or a number of the plurality of blades on the first surface differs from a number of the plurality of blades on the second surface.
