Abstract

An effective technique for increasing performance of an auxiliary handle which is attached to a power tool is provided. The auxiliary handle 200 has a grip part 210, a grip holding part 220, a mounting part 230 and a support part 240. The grip holding part 220 is disposed between the grip part 210 and the support part 240 in a longitudinal direction of the auxiliary handle 200. When the auxiliary handle 200 is attached to a power tool body, the grip part 210 and the grip holding part 220 are held so as to be movable with respect to the mounting part 230 with the support part 240 as a fulcrum.

Description

technical field [0001] The invention relates to an auxiliary handle installed on a reciprocating working tool and a reciprocating working tool with the auxiliary handle. Background technique [0002] An anti-vibration handle mounted on a working tool is disclosed in Japanese Patent Laid-Open Publication No. 2005-081517. In this anti-vibration handle, a rotation shaft is provided on the power tool main body side inside the handle portion, and a compression spring is provided on the distal end side opposite to the power tool main body side. [0003] patent documents [0004] Patent Document 1: Japanese Invention Patent Laid-Open Publication No. 2005-081517 [0005] However, in the above-mentioned anti-vibration handle, since the rotation shaft is provided inside the handle portion, depending on the structure of the handle portion, the rotation of the handle portion is restricted by the handle portion itself. Therefore, in view of the above problems, an object of the present...
