Abstract: In the guide ribs 2b of the meter unit 2 and the guide rail grooves 3b of the insertion opening 3 of the center cluster panel 1, there are formed play restrict portions 2c, 2d as well asb 3c, 3d respectively for restricting the movements of the guide ribs 2b from the time just before the mutual fitting engagement of the terminals of the two connectors 4A and 4B to the time just after the mutual connection of the two connectors 4A and 4B.
