Abstract

A driving device includes: a cylindrical-shape magazine configured to house fasteners connected in a roll form; an injecting portion configured to receive the fastener fed from the magazine; a striking portion configured to be movable in a first direction in which the fastener fed to the injecting portion is allowed to be struck and movable in a second direction opposite to the first direction; a first bias portion configured to move the striking portion in the first direction; an electrical motor moving the striking portion in the second direction; a housing configured to support the striking portion and the electrical motor; and a handle configured to protrude from the housing in a direction crossing a moving direction of the striking portion. The electrical motor has a rotary shaft, and the rotary shaft extends in a direction crossing a plan orthogonal to the moving direction of the striking portion.

Dependent claims

A driving device comprising:

a magazine configured to house a plurality of fasteners;
an injecting portion configured to receive one of the fasteners fed from the magazine;
a striking portion configured to be movable in a first direction to strike the one of the fasteners fed to the injecting portion and movable in a second direction that is opposite to the first direction;
a cylinder configured to guide movement of the striking portion;
a pressure chamber configured to be filled with a compressed gas to move the striking portion in the first direction;
an electrical motor;
a wheel coupled with the striking portion and configured to be rotated by the electrical motor to move the striking portion in the second direction;
a housing configured to support the striking portion and the electrical motor;
and
a handle configured to protrude from the housing in a third direction crossing the first and second directions,
wherein the electrical motor has a rotary shaft,
wherein the rotary shaft extends in parallel to the first and second directions, and is arranged to be adjacent to the cylinder in a fourth direction crossing the first to third directions,
wherein the rotary shaft is arranged between a center axis of the cylinder and the handle in the third direction,
wherein a rotary axis of the wheel extends in a fifth direction that is orthogonal to the first and second directions, and
wherein the cylinder and the wheel are arranged to overlap in the first and second directions.
