Abstract: An electric power tool includes a tool body having a rotor, an inner cylindrical body and outer cylindrical body. The rotor is provided with a ventilation space therearound, a body part and a brush contact part, and housed in the inner cylindrical body. The inner cylindrical body is inserted in the outer cylindrical body which has a plurality of groove-like ventilation spaces on its inner face. The rotation of a fan fitted on the rotor circulates air within the tool body through the ventilation spaces so as to cool down the body part and the brush contact part of the rotor. The electric power tool has the rotor with which not only the body part but also other heated parts are fully cooled down. The electric power tool enhances heat dissipation efficiency from a motor case, enables efficient cooling of heated parts and has a long durability.

Abstract: A tool container includes a receiving case with its upper end open and an outer bag with a hang portion, and the receiving case is insertable to and removable from the outer bag. The invention provides a tool container in which, in case of changing articles in the tool container, a worker does not have to put his or her hand or hands into the tool container, or the tool container does not have to be turned upside down, which prevents the worker from being wounded in the hand and which prevents taken-out articles from being damaged or scattering. Further articles in a pocket won't fall out inadvertently. While the container being hung on a worker's waist belt, the worker can readily change articles in the tool container. When having sharp articles such as bits, nails, knives and the like in the tool container, a bottom of the tool container won't tear and fall out.

Abstract: A carrier for holding a plurality of accumulating containers that accommodate small items. A plurality of fitting holes are formed in the flat-shaped carrier so that the shapes of the holes are substantially identical with the sectional shape of the accumulating containers in the periphery of their upper end portions, and respective accumulating containers are fitted to the fitting holes of the carrier such that at least a part of the main body of each one of the accumulating containers is exposed outside of the carrier. The carrier may alternatively be arranged by overlapping aperture sections of two flat-shaped box bodies with each other. The accumulating containers may be made so as to be transparent such that contents thereof are visible when the accumulating containers are held in the carrier, and the accumulating containers may also be made to be somewhat flexible such that they are hardly detachable from the fitting holes to which they have been fitted.

Abstract: The fluorescent lighting fixture includes a protective tube having a roulette configuration dented portions of which extend longitudinally and a rib having a long hole in which a wire is inserted. The roulette configuration appears as a stripe pattern on the protective tube and the wire inserted in the hole becomes less noticeable. When the fluorescent lamp is set alight, the light reflects, the entire protective tube becomes luminous uniformly, and the wire becomes hard to be seen. The wire can be invisible without an extra part such as a screening plate, and sufficient luminous intensity can be obtained from the entire protective tube.
