摘要： A battery pack for use with a battery-driven power tool includes three battery cells in which two out of three are arranged horizontally in parallel to and in alignment with each other in a lower case and the remaining one battery cell is vertically arranged in an upper case. The upper case of the battery pack is inserted, in use, into a battery pack receiving space formed in the grip portion of a power tool. Therefore, the grip portion can be made thin and usability of the power tool is enhanced.

摘要： An electrical power tool includes a housing, an electrical motor, an end-bit holding section, a transmitting mechanism, a cap, and a lighting section. The housing has one end. The electrical motor is accommodated in the housing and is configured to generate a rotational driving force. The end-bit holding section is provided at the one end and is rotatable about a rotational axis. The transmitting mechanism transmits the rotational driving force to the end-bit holding section. The cap is attached to the one end. The lighting section allows an entirety of the cap to be luminous.

摘要： An impact drill includes a first ratchet rotating along with a spindle and movable in an axial direction, a second ratchet engaged with the first ratchet and movable in a axial direction but unrotatable, and a spring provided between the second ratchet and a partial member of a housing. An amount of movement of the spindle in the axial direction is regulated, so that the pressing force is too excessive, the restoring force of the spring urging the second ratchet is controlled to maintain a state of generating a set stroke force.
