Abstract: A preceding engaging portion preceding a last engaging portion has a smaller diameter or is positioned further inward than the last engaging portion. Because of this configuration, an engagement of the preceding engaging portion with respect to a last engaged portion becomes more easily disengageable in comparison to the last engaging portions. When the preceding engaging portion disengages from the last engaged portion, the driver moves downward to a standby position. Accordingly, an engagement of the engaging portions with the engaged portions can be properly corrected, such that the last engaging portion engages the last engaged portion at the standby position.

Abstract: A driving tool includes a holder attached to a wheel, grease reservoirs on the holder, magnets for detecting a rotation position of the wheel, and grease flow passages for flowing grease. The holder is rotatably integrated with the wheel. The grease in the grease reservoirs flows to a supporting hole via a tilting surface of a wall, an opening hole, an extension groove and a penetrating groove.

Abstract: A driving tool includes a piston configured to move in a driving direction due to gas pressure, and a driver configured to move integrally with the piston to strike a fastener. The driver includes a plurality of rack teeth formed along a driving direction. The driving tool includes a wheel having a plurality of engaging portions to engage the plurality of rack teeth at its outer circumference. The driver is moved in a counter-driving direction as the wheel rotates. The plurality of engaging portions of the wheel includes at least one advancing/retracting engaging portion configured to move with respect to a shaft member of the wheel. The driver has a tooth groove between adjacent rack teeth of the plurality of rack teeth. One tooth groove is configured to receive the advancing/retracting engaging portion and has a depth deeper than at least one other tooth groove.

Abstract: A battery holder supported by a main body housing so as to be displaceable in an up-down direction has a main body extension, a holder lower portion at a lower part, and a terminal supported by the battery holder so as to be displaceable in the up-down direction. The battery holder has a first elastic body interposed between the main body housing and the battery holder, a second elastic body interposed between the battery holder and the terminal, and a third elastic body interposed between the holder lower portion and the main body housing. The first to third elastic bodies absorb impacts in the event of a drop, thereby reducing damage to the battery.

Abstract: A driving tool for improving shock absorbability and durability of a tubular damper, the driving tool comprising a cylinder and a piston that moves inside the cylinder owing to a gas pressure. The driving tool further comprises a driver main body to drive a driving member by moving integrally with the piston, and a lift mechanism having a wheel for the driver main body to return to original position. The driver main body is arranged such that a width center line of the driver main body is offset in a direction away from the lift mechanism with respect to a width center line of the piston.

Abstract: A driving tool includes an extension that extends from a rear guide of a nose above a driving direction and is coupled to a magazine body by a coupling screw. The tool further includes an elastic member that is arranged in between the rear guide and the magazine body and is below the coupling screw in a driving direction. The elastic member absorbs rattling of the magazine body and is integrally provided with an impact receiving portion to mitigate impact at a forward motion end position of a pusher.

Abstract: A driving tool has a configuration for preventing deviation of a driving posture of driving members from intended position during a use. The driving tool has a guide member supplied to a driving passage and a relief passage for an engagement portion of a driver to pass. The relief passage is therefore blocked by the guide member, stabilizing a driving posture of the driving member. The guide member is then pushed by a lowermost engagement portion of the driver so as to be retreaded from the relief passage, thereby allowing the engagement portion to move downward in the relief passage.

Abstract: An elastic member is disposed between an internal gear of a gear train and a gear housing. A force is applied to the gear train when a lift mechanism is activated. The force is received and absorbed by the elastic member, thereby reducing the amount of force received by the gear housing.
