Claims

[Scope of Claim for Utility Model Registration] Installation of a small lid for battery installation, which is formed by forming a small lid mounting hole in the device case in correspondence with the battery inside the device case, and removably attaching the small lid to the small lid mounting hole. In the structure, a flange having a locking protrusion and a rotation regulating protrusion is provided on one of the inner periphery of the small lid mounting hole of the equipment case and the outer periphery of the small lid, and the other is provided with a flange having a locking protrusion and a rotation regulating protrusion. Elasticity that, when the lid is placed in the small lid attachment hole and rotated, rides over the locking protrusion while overlapping the flange and comes into contact with the rotation regulating protrusion to stop the rotation of the small lid. a protrusion, and a locking recess that engages with the locking protrusion when the elastic protrusion passes over the locking protrusion;
A mounting structure for a small lid for battery mounting, characterized in that a fixing protrusion is provided which overlaps the flange when the locking recess engages with the locking protrusion.
