Fitting structure for dial plate

Abstract

Abstract PURPOSE:To easily perform fitting and removal of a dial plate without footing to the dial plate by providing a deformed hole to the dial plate by permitting a pin to pass through this hole to fix the dial plate. CONSTITUTION:A deformed hole 11b for fitting to a timepiece module 12 is formed in a dial plate 11. By providing a long groove 11c in the deformed hole 11b, a thin wall part 11e is formed on one part of the dial plate 11 adjascent to each and elasticity is given to that part. Further an arc 11d of the deformed hole 11b is detained to a taper part 13a of a pin 13 made of metal or hard rubber, pressurized to the timepiece module 12 and acts as positioning and antislip of the dial plate 11.
