Abstract
A microwave oscillation circuit unit to be installed on one surface of a chassis base having a circuit substrate on its other surface. The unit is provided with at least two screws, and a power supply terminal and an output terminal on its one surface confronting the chassis base when installed on the chassis base. In such a structure, a first nut is threaded on one of the screws which is positioned adjacent to the power supply terminal and the output terminal so that torque caused by tightening the first nut to such one of the screws may act upon the chassis base, the first nut being clear from the circuit substrate. Furthermore, a second nut is threaded on the other of the screws which is positioned apart from both the terminals so that torque caused by tightening the second nut to the other of the screws acts upon both the chassis base and the circuit substrate.
