CONTROL DEVICE MOUNTING DEVICE

PROBLEM TO BE SOLVED: To provide a highly reliable control device mounting device improved into such a structure that even if there is an irregularity in the clamping amounts of fastening screws by clamping the fastening screws screwed into a buried adaptor in a somewhat excessive manner or the like when a control device is mounted to a panel, such as a control panel, the pawls of the adaptor and engaging grooves formed in the side surface of a case for the control device are prevented from falling off and the device can be fixed on the panel with good stability. SOLUTION: A control device mounting device is one of a structure, wherein the wall of a panel 2 is inserted between a front flange part of a control device 1 and a frame-shaped buried adaptor 3 with hook pawls, which is fitted into the outer periphery of a case main body from the back of a case, has the hook pawls formed on the side surface of the case and is made to engage with engaging grooves 1a formed in the side surface of the case, and the points of fastening screws 4 screwed into the peripheral edges of the adaptor 3 are pressed to the rear of the panel 2 to fix the device 1 on the panel. Elastic pads 5 are respectively supported movably on the points of the screws 4 as interference members for absorbing an irregularity in said fastening screw clamping amounts, the irregularity in the clamping amounts of the fastening screws is absorbed by the deflection of the pads 5 and the control device 1 is fixed on the panel with good stability.
