This invention provides an electrical apparatus that includes a main body portion, a battery pack, and a frame portion. The main body portion comprises a converting portion that may convert electric power to one of light, wind, heat, and sound; and an outputting portion. The battery pack may detachably mounted on a battery holder provided at the main body portion, and may supply electric power to the converting portion. The frame portion may rotatably support the main body portion, and may define a first ground contact plane that can contact a ground surface and a second ground contact plane that can contact the ground surface at a different angle from an angle of the first ground contact plane. The main body portion may be rotatable relative to the frame portion without contacting the ground surface.

Electric device outputting light, wind, heat or sound

Nailer

Storage case for portable tool

An electric device includes: a device body; and a frame guard. The device body has a plurality of surfaces for defining a three-dimensional configuration. The frame guard is configured to guard the device body. The frame guard is connected to the device body and disposed outside the device body. The plurality of surfaces is all disposed inside the frame guard.

Electric device with surrounding protective frame

A power tool includes a housing including: a body part having a substantially cylindrical shape and extends in a front-rear direction; and a handle part connected to the body part. The body part includes: a driving source; a power transmission mechanism part configured to transmit a driving force of the driving source; and a tip tool holding part to which the driving force of the driving source is transmitted from the power transmission mechanism part. The handle part includes a switch. A top part protruding from a surface of the handle part is formed on a side surface of the handle part along a longitudinal direction of the handle part. At least a portion of the top part is arranged at a position deviating rearwards from a center of the handle part in the front-rear direction.

Portable electric driver

Radio receiver

An electric driver includes a hook portion which is constituted by a deformable hook-like portion and a connecting portion for connecting the hook-like portion to the handle. The hook-like portion is constituted by a base portion connected to the connecting portion and a bent portion continuous to the base portion, and a front end portion continuous to the bent portion and arranged at a position substantially opposed to the base portion. The front end portion and the base portion can be proximate to and remote from each other. The connecting portion holds the hook-like portion in a direction substantially the same as a direction in which the handle extends. The hook-like portion is pivotably held on a first rotating axis center extending in substantially the same direction as the handle.

A cover which covers outer peripheries of fastening screws are disposed on an outer periphery of a hammer case. A stopper which detachably positions and fixes the cover to the outer periphery of the hammer case is disposed.
