摘要： PROBLEM TO BE SOLVED: To provide a reciprocating tool in which constant vibration reduction effects can be obtained by intercepting vibration transmission from the cutting tool side regardless of characteristics of a material to be cut.
SOLUTION: The reciprocating tool is provided with a motor stored in a body housing 15 and a reciprocation converting mechanism for converting the rotation of an armature 9 of the motor to the reciprocation of a plunger 5. Cutting is executed by the reciprocation of a blade (a cutting tool) 2 mounted to the plunger 5 in the reciprocating tool. An elastic material 21 is interposed between a gear holder (a part of the reciprocation converting mechanism) 11 and the body housing 15. The vibration accompanying with reaction force of a load acting on the blade 2 during the cutting is absorbed by the elastic material 21. Propagation of the vibration to the body housing 15 is intercepted. Consequently, the vibration of the body housing 15 is reduced. The constant vibration reduction effects can be obtained regardless of the characteristics of the material to be cut.
