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 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 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 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.

IPC: B25C1/04
Abstract: A driving tool comprises a cylinder extending in an up-down direction and a piston that moves downward within the cylinder due to a compressed gas to drive a driving member. The driving tool further comprises a main body housing that houses the cylinder and a grip extending rearward from a rear surface of the main body housing. The driving tool further comprises an upper chamber that is provided above the cylinder and communicates with the cylinder. The driving tool further comprises an air chamber that extends downward from the upper chamber and that extends only in an area on a right or left side of the main body housing with respect to both an axis center of the cylinder and an axis center of the grip.
