Title:
DRIVE TOOL
Document Type and Number:
Japanese Patent JP2022061853
Kind Code:
A
Abstract:
To provide a drive tool that is capable of reducing vibration in use and can be compact in size.SOLUTION: A drive tool comprises: a main shaft 18 which is driven to rotate around an axis J as a center of rotation and has an eccentric part 25 which is centered at a position off the axis J; a movable body 38 which has a long hole 35 into which the eccentric part 25 is inserted, which is reciprocated linearly in an X-direction orthogonal to the axis J by rotating and moving around the axis J along with rotation of the main shaft 18 with the eccentric part 25 in contact with the long hole 35, and to which a tip tool can be attached; a counter weight 32 which is disposed so as to linearly reciprocate in the X-direction; and a transmission mechanism 49 which transmits movement force when the movable body 38 linearly reciprocates to the counter weight 32, causing the counter weight 32 to linearly reciprocate in the X-direction and in a direction opposite to the reciprocation direction of the movable body 38. The counter weight 32 is arranged on the axis J.SELECTED DRAWING: Figure 4
