Abstract: A structuring technique contributes to the rationalization of dispositioning parts and operability with respect to a striking tool wherein usual operation is defined as a striking operation to the downward in a state that the striking tool is downwardly dropped by the own weight of the striking tool. A striking tool is held by a pair of handles by both hands while striking operation takes place when the striking tool drops downwardly by the own weight, a drive mechanism drives an end tool in a first direction and motor, wherein the output shaft of the motor extends in a third direction defined as a thickness direction to cross the first direction and the second direction, and a battery mounting portion is disposed at the side region of the main housing in the second direction, wherein a battery to supply electricity to the motor is mounted to the battery mounting portion.

Abstract: A reciprocating tool includes a motor, a driving mechanism, a body housing, a movable part, and a vibration control mechanism. The driving mechanism includes a reciprocating member configured to reciprocate in a first direction. The movable part is connected to the body housing via a first elastic member and a second elastic member to be relatively movable in the first direction. The vibration control mechanism includes at least one weight configured to move in a direction opposite to the reciprocating member. The center of gravity of the at least one weight is offset from the driving axis in a second direction. In the second direction, the first elastic member is closer to the center of gravity than the second elastic member. A load of the first elastic member when the movable part is placed in a closer position is smaller than a load of the second elastic member.

Abstract: A power tool includes a motor, a housing, a battery holder and a cushion. The battery holder is held by the housing to be movable at least in a first direction relative to the housing. The battery holder is configured to removably receive a battery for supplying electric power to the motor. The cushion is held by the housing such that the first direction intersects the cushion. When the battery is attached to the battery holder, the cushion is directly or indirectly disposed between the battery and the housing.

Abstract: A dust collecting system includes a power tool and a stationary dust collector. The power tool is configured to perform processing operation on a workpiece by driving a tool accessory. The stationary dust collector is configured to be placed separately from the power tool and to collect dust generated by the processing operation. The power tool includes a first motor and a driving mechanism configured to drive the tool accessory by power of the first motor. The dust collector includes a second motor and a fan configured to be rotationally driven by the second motor to generate air flow for collecting dust. The dust collecting system includes a control device configured to control a rotation speed of the second motor according to a driving state of the power tool.

Abstract: A power tool includes a drilling tool and a dust collector configured to be removably attached to the drilling tool. The dust collector includes a dust collector body, a passage part provided in the dust collector body and having elasticity, and a storing part configured to be removably attached to the dust collector body and to store dust. The passage part includes a drilling tool mounting port part configured to be connected to the drilling tool while pressing a specified region of the drilling tool, and a storing part mounting port part configured to be connected to the storing part while pressing a specified region of the storing part. Air containing the dust is led through the dust collector body to the storing part, and the air from which the dust has been separated in the storing part is led through the passage part into the drilling tool.

Abstract: A dust collector includes body, a dust-storing part, a sliding part, a dust-transfer passage, and a biasing member. The sliding part is held by the body to be slidable in a specified axial direction and has a suction port. The dust-transfer passage connects the suction port and the dust-storing part. The biasing member biases the sliding part in a first direction of the axial direction. The sliding part is configured to be normally held in an initial position in which the sliding part protrudes from the body by a specified length in the first direction, and to be moved in a second direction opposite to the first direction against the biasing force when pressed in the second direction. The dust collector includes a cushioning member configured to be interposed between the body and the sliding part in the axial direction when the sliding part is placed in the initial position.

Abstract: A dust collector includes a main body, a sliding part, and a communication passage. The main body includes an internal region disposed between a power tool and a dust storing region. The sliding part is held by the main body so as to be slidable in a first direction while partly protruding out of the main body through an opening and partly disposed in the internal region. The communication passage extends in a second direction crossing the first direction within the internal region. When the sliding part is placed at a closest position, a distance in the first direction between the opening and an innermost end of the sliding part is longer than a distance between the opening and the communication passage. The sliding part includes an interference avoiding part configured to avoid interference with the communication passage when the sliding part is placed at the closest position.
