Abstract: An impact driver includes a hammer that is rotated by a motor and an anvil configured to be struck by the hammer to rotate the anvil about a rotational axis. A hammer case houses the hammer. Two or more bearings are provided inside the hammer case and support the anvil. To inhibit vibration of the anvil during operation, the bearings may be differing types, such as a regular ball bearing and an angular contact ball bearing, and/or the bearings may have different inner and/or outer diameters. A contact member, such as an O-ring, may be disposed in an insertion hole of the anvil to reduce vibrations that are transmitted to the tool bit.

Abstract: An electrical device includes a battery-mount part (40) configured such that a battery used as a power supply of a power tool is mountable thereon, and a heat-generating element (54) for boiling water using electric power from the battery (B1, B2) mounted on the battery-mount part. The electrical device further includes a drip case (21) for holding a pod, in which a predetermined amount of tea leaves or coffee grounds is encased in a permeable bag-shaped element. A hot water supply (50y) supplies the water boiled by the heat-generating element (54) automatically to the drip case (21). An extraction part (21p) in the drip case (21) allows a beverage produced by the hot water that has been poured onto (injected into) the pod to downwardly flow.

Abstract: A tool-holding apparatus (70) includes an engaging member (71) for engaging a tool accessory (B) and being movably supported in axial and radial directions in a rotational-output shaft (26) having an insertion hole (81) for holding the tool accessory (B). A first biasing member (72) biases the engaging member towards engagement with the engaging member. A bit sleeve (73) is movable in the axial direction along an outer-circumferential surface of the rotational-output shaft between a blocking position at which radial outward movement of the engaging member is blocked and a permitting position at which radial outward movement of the engaging member is permitted. A second biasing member (74) biases the bit sleeve toward the blocking position. A positioning part (75) is fixed on the outer-circumferential surface of the rotational-output shaft and stops the bit sleeve at the blocking position. The bit sleeve has a projection (88), which is disposed on the forward side of the first biasing member, extends inward in the radial direction, and slidably contacts the rotational-output shaft.

Abstract: An impact tool (1; 1A) includes a spindle (12) rotated by a motor (10) and a hammer (70) held by the spindle. The hammer is designed to impact an anvil (14) in a rotational direction. A case (8) houses the hammer. A first bearing (78A) and a second bearing (78B) are held in the case and arranged along the axial direction. The first bearing and the second bearing directly hold the anvil in a rotatable manner.

Abstract: A technique reduces an increase in the size of an impact tool. An impact tool includes a motor, a striker drivable by the motor, an anvil including an anvil shaft to receive a tip tool, and an anvil projection protruding radially outward from a rear end of the anvil shaft to be struck by the striker in a rotation direction, a hammer case accommodating the striker, a bearing held in the hammer case and surrounding the anvil shaft, a ring member at least partially facing a front surface of the anvil projection and in contact with a rear end face of the bearing, and a stopper engaging with the hammer case and the ring member to reduce moving of the ring member rearward.
