Claims

[Scope of utility model registration request]

a front panel; a push button having elasticity that is inserted into a button insertion hole formed in the front panel and pressed from the outside; a liquid crystal display disposed inside the front panel; and a liquid crystal fixing plate fixed to the inner surface of the front panel, and the push button has a substantially U-shaped annular groove on the outer peripheral surface of the base thereof, the groove depth direction being in the axial direction of the push button and opening toward the tip of the push button.
A letter-shaped annular fixing part is integrally provided, and an annular protrusion that fits into the annular groove of the annular fixing part is integrally provided on the inner surface of the surface panel at the peripheral edge of the button insertion hole so as to protrude inwardly. The liquid crystal fixing plate includes a first annular protrusion that holds the bottom part of the annular fixing part together with the annular protrusion of the front panel, and a second annular protrusion that pinches the outer peripheral wall of the annular fixing part together with the annular protrusion. A push button waterproof structure for a display device, characterized by integrally having an annular convex portion.
