Battery

Driver tool

In order to obtain an illuminating device that can carry out optimum illumination corresponding to various usage modes, the illuminating device includes a grip held by an operator and extending in a vertical direction; a battery connected to a lower end of the grip; and an irradiation part connected to an upper end of the grip, and the irradiation part is connected to the grip so that the irradiation part can be turned between a first position extending from the upper end of the grip to an upper side and a second position extending from the upper end of the grip to a lower side, a first lamp is provided on a grip-side end part of the irradiation part, and a second lamp is provided on a side surface of the irradiation part.

Illuminating device

Portable nailing machine body

Portable electric power circular saw

Portable electric driver body

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

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

Portable electric driver

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.
