The objective of the present invention is to provide a working machine with which an increase in size of the working machine can be suppressed. This objective is achieved by the working machine in which a work tool rotates under the motive force of a motor, and the working machine comprises: a transmission mechanism which transmits a rotational force of the motor to the work tool; a front case (25) in which the transmission mechanism is disposed; a gripper (36) of which a fin is attached by projecting from an outer surface of the front case (25) and which is grasped by an operator; and an attachment hole (41) which is provided in the front case (25) and to which the gripper (36) is attached, wherein the attachment hole (41) penetrates through the front case (25) as seen in a plan view intersecting an axis (A1) which is the center of rotation of the work tool.
