Abstract: A reciprocating tool includes a body housing, a handle member and an elastic member. A first one of the body housing and the handle member includes a first coupling part, while a second one includes a second coupling part. The first coupling part includes an internal space, and an opening that communicates with the internal space and an outside space of the first coupling part. At least a portion of the second coupling part protrudes into the internal space through the opening and is movable relative to the first coupling part in the front-rear direction within the opening. The elastic member is disposed in the internal space and is configured to bias the first coupling part and the second coupling part such that the body housing and the handle member are biased away from each other in the front-rear direction.

Abstract: A power tool includes a motor, an output shaft, a chip-on-board light emitting diode, and a light cover. The output shaft is rotated by a rotational force of the motor. The chip-on-board light emitting diode is disposed around the output shaft. The chip-on-board light emitting diode includes: a substrate including a circular ring portion; and an LED chip disposed on a front surface of the circular ring portion. The light cover is fixed to the substrate. The light cover includes: an outer cylindrical portion disposed radially outside with respect to the circular ring portion; and a light transmission portion through which light emitted from the LED chip passes. An opening is provided in a lower portion of the outer cylindrical portion.

Abstract: A display device may include: a first light emitting part that emits light; a second light emitting part that emits light; and a housing. The housing may include: a transmissive part defining an internal space in which the first and second light emitting parts are disposed, and that transmits light from the space of the housing to outside the housing; a partition wall part integrally formed with the transmissive part and partitioning the space of the housing into a first accommodating space where the first light emitting part is disposed and a second accommodating space where the second light emitting part is disposed; and a first shielding part disposed on a surface of the transmissive part, having a light transmittance smaller than a light transmittance of the transmissive part, and defining a first display element in the first accommodating space and a second display element in the second accommodating space.

Abstract: A power tool attachment efficiently guides light and provides sufficient illumination when attached to a power tool. A power tool attachment is attachable to a power tool to cover a light source included in the power tool. The power tool attachment includes a light guide being a single member made of a transparent resin. The light guide includes a light receiver that receives light from the light source when the power tool attachment is attached to the power tool, and a light emitter that outputs the received light.

Abstract: An intended illumination area is illuminated with light. An electric work machine includes a motor including a rotor rotatable about a rotation axis extending in a front-rear direction, an output unit located frontward from the motor and operable under a rotational force from the rotor, a light emitter, and an optical member including at least one light receiver that receives light from the light emitter and a light guide surrounding at least a part of the output unit to allow light from the at least one light receiver to travel through the light guide. The light guide has a rear surface having at least one slit, and a front surface to allow emission of light traveling through the light guide and reflected at the at least one slit.
