1. A power tool configured to drive a tool accessory in an oscillating manner, the power tool comprising:
an outer housing that is a hollow body having a longitudinal axis that defines a front-rear direction of the power tool, the outer housing including a front part, a rear part and a grip part, the grip part connecting the front part and the rear part and being configured to be held by a user;
an inner housing extending in the front-rear direction within the outer housing and elastically connected to the outer housing, the inner housing including a front part disposed within the front part of the outer housing, a rear part disposed within the rear part of the outer housing and an extending part extending rearward from the front part of the inner housing within the grip part of the outer housing;
a spindle housed in the front part of the inner housing and configured to be driven in rotary oscillating motion within a specified angle range around a first axis that defines an up-down direction of the power tool, the spindle having a lower end portion configured to removably receive the tool accessory;
a control device housed in the rear part of the inner housing and configured to control operation of the power tool;
a holder disposed in and directly connected to the extending part of the inner housing and holding an electric wire that extends from the control device; and
a weight held on the extending part of the inner housing and directly engaging the holder,
wherein:
the holder is located between the extending part and the weight in the up-down direction,
the weight increases the moment of inertia of the inner housing with respect to the first axis;
the holder includes a protrusion that extends upward from an upper surface of the holder in the up-down direction at a location that is in-between front and rear ends of the holder in the front-rear direction, and
the weight has a projection that engages in the protrusion of the holder.
