Abstract

PURPOSE:To facilitate the assembling work of a clock body by making a window in the side plate or the bottom plate of the exterior frame of a clock and fitting a component cover integrally in the window thereby preventing the cover from sinking or falling. CONSTITUTION:A window 31 is made in the side plate 11 of the exterior frame of a table clock, for example, and a component cover 40 is fitted therein. In this regard, an enlarged recess 33 is made in the peripheral edge of the window 31 so that the inside part of the window 31 is larger than the outside part thereof thus preventing the cover 40 from sinking to the inside. The window 31 is then clamped, at the upper fringe thereof, by a frame part 49 and a protrusion 53 formed at the upper circumferential wall part 41 so that the cover 40 is rotated about the protrusion 53. When the lower circumferential wall part 44 is pushed strongly into the window 31, a micro bulging part 55 abuts against the lower edge of the window 31. The bulging part 55 is then inserted into the inside of the side plate 11 through slight resilient deformation of the cover 40 or the side plate 11 and the cover 40 is fitted in the window 31 to be secured in place. This structure facilitates the assembling work of a clock including the automation thereof.
