Abstract
The present invention makes it possible to, in a configuration provided with electrical components such as an inverter device for controlling an electric motor, obtain a high degree of freedom with regard to the layout of the electrical components and efficiently place the electrical components in a limited space. An excavator comprises: an electric motor; a hydraulic fluid tank in which hydraulic fluid is stored; a hydraulic pump that is driven by the electric motor and supplies the hydraulic fluid within the hydraulic fluid tank to an actuator; and an inverter device that, with respect to the hydraulic fluid tank, is provided at a position away from a left-side surface part of the hydraulic fluid tank.
