Title:
IMPACT TOOL
Document Type and Number:
WIPO Patent Application WO/2014/142112
Kind Code:
A1
Abstract:
[Problem] To provide an improved technique pertaining to the rational placement of constituent elements of an impact tool. [Solution] There is provided a hammer drill (100) for driving a hammer bit (119) detachably mounted on the distal end region of a main body part (101). The hammer drill (100) has: a driving motor (110) for driving the hammer bit (119); and a motion conversion mechanism (120) for converting the rotational motion of the driving motor (110) into linear motion in the long-axis direction of the hammer bit (119). The driving motor (110) is disposed further toward the distal end region than a rotation body (124), which represents the pivot of a swinging member (125), so that the motor shaft (111) extends in an intersecting direction which intersects the long-axis direction of the hammer bit (119).
