IMPACT TOOL
An impact tool includes: a spindle which makes a rotation motion; a hammer which makes a reciprocating motion in a longitudinal direction; a spring whose front end is supported on the hammer side and rear end is supported on the spindle side; and a stopper fixed to the spindle so that it abuts on the hammer when the hammer is moved rearward, and the rear end of the spring and the stopper are mutually overlapped with each other in the longitudinal direction.

13 . An impact tool comprising:
a spindle which includes a spindle shaft portion extending in a longitudinal direction and a carrier portion located on a rear side of the spindle shaft portion, extending in a radially outward direction relative to the spindle shaft portion, and supporting a planetary gear mechanism and makes a rotation motion;
a hammer which is provided on an outer periphery of the spindle shaft portion and on a front side of the carrier portion and makes a reciprocating motion in the longitudinal direction with respect to the spindle;
a spring which is provided between the carrier portion and the hammer in the longitudinal direction and applies a force to the front side to the hammer; and
a washer which is provided between the carrier portion and a rear end of the spring in the longitudinal direction,
wherein the carrier portion has a through hole which supports a planetary gear shaft constituting the planetary gear mechanism,
the washer is provided so as to partially close the through hole, and
the carrier portion has a protruding portion which protrudes to the front side from a front surface of the carrier portion on a radially outer side relative to the washer.
14 . The impact tool according to claim 13 ,
wherein the planetary gear mechanism includes an inner gear attached to a rotation shaft of a motor, a planetary gear engaged with the inner gear, an outer gear engaged with the planetary gear and the planetary gear shaft serving as a shaft of the planetary gear and supported by the carrier portion, and
the protruding portion protrudes to the front side from the front surface of the carrier portion located opposite to the planetary gear on a radially outer side relative to the planetary gear shaft.
15 . The impact tool according to claim 13 ,
wherein the protruding portion restricts movement of the washer in a radial direction with respect to the carrier portion.
16 . The impact tool according to claim 13 ,
wherein the through hole is located on an inner side relative to the spring in a radial direction.
17 . The impact tool according to claim 13 ,
wherein the protruding portion is formed over an entire periphery of the carrier portion.
