摘要： In order to provide a working machine capable of suppressing an increase in size, a working machine that rotates a working tool with motive power of a motor includes a transmission mechanism that transmits a rotational force of the motor to the working tool, a front case in which the transmission mechanism is disposed, a holding tool that is attached to the front case so as to protrude from an outer surface of the case and is gripped by a worker, and an attaching hole which is provided in the front case and to which the holding tool is attached, and the attaching hole penetrates the front case in plan view intersecting with an axis that is a rotation center of the working tool.
