摘要： [Technical Problem]
Provided is a rotation preventing ring-shaped member preventing a second element threadedly joined to a first element from being rotated in a threaded engagement releasing direction.
[Solution to Problem]
The rotation preventing ring-shaped member has a ring-shaped body 32 circumferentially disposed around the outer peripheral surface of a forward end of the first element (cylindrical chisel body) 26 at the threaded joint, a first locking portion 34 provided at one end of the ring-shaped body, a release portion 36 provided at the other end of the ring-shaped body, and a second locking portion 38 provided at a position intermediate between the first locking portion and the release portion. The first locking portion locks the ring-shaped body to the first element circumferentially, and the second locking portion engages the second element (forward end cylindrical member) 24 to prevent rotation of the second element in a threaded engagement releasing direction. By displacing the release portion in a direction extending toward the above-described one end along the ring-shaped body, the ring-shaped body is caused to curve radially outward, thereby disengaging the second locking portion from the second element and thus allowing rotation of the second element in the threaded engagement releasing direction.-

摘要： Provided is a liquid pump configured to suppress discharge of air from an air pool formed in a discharge-side tank. A discharge-side tank part 28 formed in a housing 16 has a first inner wall surface 28c and a second inner wall surface 28d facing each other in a horizontal direction in an installed position of the liquid pump 10. The first inner wall surface 28c is formed with a discharge port 22, and the second inner wall surface 28d is formed with an opening 46a of a discharge-side communicating passage 46. An air pool A2 is formed in a space in the discharge-side tank part 28 above the opening 46a of the discharge-side communicating passage 46 and the discharge port 22. A circular cylindrical partition 48 is provided in the discharge-side tank part 28. The circular cylindrical partition 48 projects from the second inner wall surface 28d toward the first inner wall surface 28c with at least a portion of the cylindrical partition positioned above the opening 46a of the discharge-side communicating passage 46 so as to cover the opening 46a as seen from the air pool A2 side.

摘要： Provided is a pipe coupling member configured to prevent a coil spring from being plastically deformed or dislodged from a coupling body even when a large force acts on a valve element. A pipe coupling member (10) includes a coupling body (14) having a fluid passage (12), a valve element (16) displaceable in the fluid passage (12), and a coil spring (18) urging the valve element (16) toward a closed position. The coil spring (18) is formed by helically winding a wire and has a fitting portion (18a) fitted and secured in a spring fitting groove (26), a locking portion (18b) contiguous with the fitting portion (18a) and having an outer diameter larger than the inner diameter of the fitting portion (18a) when fitted in the spring fitting groove (26), a valve support portion (18e) supporting the valve element (16), and an expanding-contracting portion (18c) extending between the locking portion (18b) and the valve support portion (18c) to expand and contract. When the coil spring (18) is compressed, the locking portion (18b) is supported by the fitting portion (18a) and thus prevented from passing through the fitting portion (18a).

摘要： [Technical Problem] Provided is a threaded member tightening tool capable of returning a count value in linkage with reverse driving by the threaded member tightening tool and only when a threaded member to be removed by the reverse driving has been counted as a tightened threaded member.
[Solution to Problem] A computing unit of a motor-driven screwdriver is switchable between a counting mode in which the computing unit counts the number of tightened threaded members and holds the counted number as a count value and a count return mode for returning the count value to a one-preceding count value. The computing unit returns the count value to a one-preceding count value based on the fact that the engaging element fitting unit has been driven in the reverse direction when the computing unit has been switched to the count return mode.-

摘要： [Technical Problem] Provided is a drilling machine configured to prevent entry of dust and water into a connector terminal part of a battery. [Solution to Problem] A battery-operated drilling machine (10) has a drilling drive unit (14) having a motor (48) for rotationally driving a drilling tool (44), a drilling machine body unit (12) supporting the drilling drive unit (14) vertically movably, and a battery cover (30) attached to the drilling machine body unit (12). The drilling machine body unit (12) is provided with a battery loading part (28) for accommodating a battery (16). The battery cover (30) is movable between a retracted position and an advanced position relative to the battery (16) loaded in the battery loading part (28). The battery cover (30) covers at least a part of a gap between the drilling machine body unit (12) and the battery (16) when the battery cover (30) is in the advanced position.

摘要： There is provided a drilling machine using a battery to drive an electromagnet for securely holding a drilling machine body unit and to drive a motor rotationally driving a drilling tool. The drilling machine (10) has a body unit (12), an electromagnet (18) attached to the body unit to securely hold the body unit, a drilling drive unit (14) that has a motor (48) for rotationally driving a drilling tool (44) and that is attached to the body unit so as to reciprocate relative to the body unit to move the drilling tool toward and away from a workpiece to be drilled by the drilling machine, a drive control circuit provided in the body unit to drive and control the motor and the electromagnet, and a battery (16) connected to the drive control circuit. The motor and the electromagnet are drove and controlled by the drive control circuit using the battery as a power source.

摘要： [Technical Problem] A lead wire of a drilling machine is routed so that a curved portion of the lead wire is not exposed to the outside and that the load on the lead wire is reduced. [Solution to Problem] A lead wire (50) connecting together a drive control circuit (12) in a body unit (20) of a drilling machine (10) and a motor (36) in a drilling drive unit (30) is led out from the motor to extend downward into a lead wire housing part (70) in the body unit through a lead wire passage (60) between the body unit and the drilling drive unit. In the lead wire housing part, the lead wire is curved and directed upward to lead to the drive control circuit, with an upwardly directed portion (52) held by a holding part (84). Thus, when the drilling drive unit (30) moves upward relative to the body unit (20), a part of the lead wire (50) is paid out upward from the lead wire housing part (70) into the lead wire passage (60), and a curved portion (54) moves upward in the lead wire housing part. When the drilling drive unit moves downward relative to the body unit, the lead wire moves reversely to the above.
