Abstract:
To provide a key case structure that can be opened easily when exchanging batteries but cannot be opened due to an impact of dropping or the like.SOLUTION: This invention relates to a key case structure that has an inner case 3 and an outer case 4. The outer case 4 is divided into an upper case 6 and a lower case 7. While the upper case 6 and the lower case 7 face each other, protrusions 11, 12 that are formed on the inside of dividing surfaces 9 of the upper case 6 and the lower case 7 respectively are fitted and locked together in a groove 13 provided on the periphery of the inner case 3. The dividing surface 9 of the lower case 7 is provided with an outer step 32, and the dividing surface 8 of the upper case 6 is provided with an inner step 33. The inner step 33 restricts deformation of the dividing surface 9 of the lower case 7 in a manner of expanding outward in a dividing surface direction 34 by the outer step 32 being locked in the dividing surface direction 34.SELECTED DRAWING: Figure 4
