Title:
DRIVING TOOL
Document Type and Number:
WIPO Patent Application WO/2022/075341
Kind Code:
A1
Abstract:
This driving tool comprises: a main shaft (18) that is rotationally driven to rotate about an axial line (J); an eccentric part (25) that is provided to the main shaft (18) and that has a center offset from the axial line (J); a movable body (38) which has a long hole (35) having inserted thereto the eccentric part (25), which linearly reciprocates in an X direction orthogonal to the axial line (J) when the eccentric part (25) rotationally moves around the axial line (J) according to the rotation of the main shaft (18) while being in contact with the long hole (35), and to which a leading-end tool can be attached; a counter weight (32) disposed so as to linearly reciprocate in the X direction; and a transmission mechanism (49) that transmits moving force, generated when the movable body (38) is linearly reciprocating, to the counter weight (32) to cause the counter weight (32) to linearly reciprocate in a direction reverse to the movable body (38) in the X direction. The counter weight (32) is disposed on the axial line (J).
