Claims

1. The aircraft and, The engine mounted on the aforementioned aircraft, The hood covering the engine, A control device positioned above the hood, A control device located below the aforementioned control device and inside the hood, A cover member that covers the upper part of the control device, The mounting portion to which the cover member is attached, A mounting device for attaching the cover member to the mounting portion, Equipped with, The cover member is positioned so as to be inclined downward toward a position horizontally away from the control device. The mounting portion has a contact portion, The cover member has a contact portion, The contact portion is a work machine that, by contacting the contact portion, restricts the rotation of the cover member around the mounting fixture and holds the cover member in a downward inclined position.

2. The work machine according to claim 1, wherein the cover member is positioned above the control device to receive intruders entering from between the control device and the bonnet.

3. A cooling fan that generates cooling air to cool the prime mover, A cooler positioned upstream of the prime mover in the direction of the cooling airflow, Equipped with, The work machine according to claim 1, wherein the control device is arranged downstream of the prime mover in the direction of the cooling airflow.

4. The system includes a hydraulic pump driven by the aforementioned prime mover, The work machine according to claim 3, wherein the control device is located above the hydraulic pump.

5. The system is equipped with a muffler through which exhaust gas from the aforementioned prime mover is guided, The work machine according to claim 3, wherein the control device is positioned above the muffler.

6. The work machine according to claim 1, further comprising a heat shield that shields against heat from the prime mover side so as not to be transmitted to the control device.

7. The device is equipped with a mounting bracket to which the control device is attached, The work machine according to claim 6, wherein the mounting bracket is arranged at a distance from the heat shield.

8. The bonnet is equipped with a support frame that is erected on the aircraft body and supports the bonnet, The work machine according to claim 7, wherein the mounting bracket is attached to the support frame.

9. The aircraft and, The engine mounted on the aforementioned aircraft, The hood covering the engine, A control device positioned above the hood, A control device, which is an ECU, is located below the control device and inside the bonnet, and controls a solenoid valve that operates a control valve equipped on the work machine. A cover member that covers the upper part of the control device, A heat shield that blocks heat from the prime mover side from being transmitted to the control device, Equipped with, The heat shield covers the control device from below. The control device is positioned in the work machine between the cover member and the heat shield in the vertical direction, and in a plan view, overlaps with the cover member, the heat shield and the control device, such that its vertical length is shorter than its horizontal length.
