Abstract

A hole cover mountable in a hole in a panel without exceeding the specified value for the insertion load, and which is capable of remaining secure after mounting. The relative movement between locking claws and a panel from the start of the hole cover insertion until mounting is complete is indicated by the movement strokes upward from a reference line R on the panel. The magnitude of the insertion load with respect to each stroke is determined by the shapes of the respective inclined surfaces. The peak load-generating stroke position (dash-dot-dot line) at the time of panel insertion is controlled by giving the inclined surfaces on the locking claws of the hole cover different shapes, thereby keeping the insertion load peak value for the hole cover product as a whole within the specified value for the insertion load.
