工が必要であつた。 As shown in Figure 1, the conventional structure is that a gasket made of an elastic member is held between the upper part of the outer case, a cover glass is attached to the outer case from above, and a back cover is screwed or punched onto the outer case at the bottom. As shown in Fig. 2, a cover glass having an outer shape larger than the inner shape of the brim is attached from below to the upper brim of the outer case, and the outer circumference of the cover glass is By placing a rubber gasket under the case back and engaging the inner case, which is integrated with the case back, with the outer case using a spring, etc., the outer case can be inserted through the upper end of the rising part of the outer periphery of the inner case and the outer periphery of the cover glass. The watch case was constructed by pressing the rubber gasket between the collar and the collar. However, in the former case, since the cover glass is attached from above, the inner shape of the flange on the top surface of the outer body that constitutes the packing box must be larger than the outer shape of the cover glass, and the packing will be visible after installation. In addition, machining the grooves to form the packing box was also difficult and costly. Furthermore, the engaging portion of the back cover also required threading or biting protrusion processing, depending on the engagement type. Also, when assembling and disassembling the camera, the glass and back cover had to be assembled and disassembled separately. In addition, in the latter case, the shape of the cover glass is complicated, and as in the former case, it is necessary to process the biting part of the inner shell.

ヤルリング落ち溝41aが設けられている。 The present invention will be explained based on examples. FIG. 3 is a partial cross-sectional view showing an embodiment of the present invention, in which a mechanical body 3 is attached to an inner step 31a of a bowl-shaped inner case 31 made of synthetic resin or soft metal, which is integrated with the back cover.
The outer peripheral collar portion 35a of No. 5 is held unrotatable from above (by making the planar shapes mutually irregular, engaging the concave and convex portions, etc.). Machine body outer periphery collar 35
At the upper part of the machine body 35, a dial ring 32 made of metal, plastic, etc. whose outer shape is guided by the inner body inner wall part 31b, which is larger than the outer diameter of the machine body outer circumferential collar part 35a, is attached to a dial ring 32 that is attached to the upper part of the machine body 35. It is attached to the plate 36 with a cutout shape. A cover glass 33 whose outer shape is guided by the inner wall portion 31b of the inner body is attached to the upper part of the dial ring 32. The outer periphery 31c of the inner casing 31 is held between the inner wall 34a of the outer casing 34 and the outer periphery end of the cover glass 33 with an interference margin. The upper surface of the outer body is provided with a flange portion 34b having an inner diameter smaller than the outer diameter of the cover glass 33 and having a thickness protruding from the upper surface of the cover glass. Outer shell inner wall part 34

A V-shaped bite groove 54b is provided on the outer shell inner wall portion 54a which has a tightening margin and engages with the outer shell inner wall portion 54a. Reference numeral 51b denotes a protrusion for preventing rattling of the mechanical body, which is provided around the entire circumference or partially of the inner wall portion 51a of the inner cylinder. In the case of FIG. 6, a biting protrusion 61a is provided on the entire circumference or part of the outer periphery of the inner shell, and is bitingly engaged with a corresponding biting groove 64a on the inner wall of the outer shell. Note that the dial-equipped mechanical body 65 is fixed to the inner shell 61 by a collar portion 65a, and a dial ring drop prevention step provided on the inner wall portion 61c of the inner shell 61 is provided on the dial ring fall step portion 61b of the inner shell 61. A dial ring 62 whose outer shape is guided by the projection 61d is attached, and a cover glass 63 whose position is vertically determined by the dial ring 62 is attached onto the dial ring.

周部をすつきり見せることができる。 According to the present invention, after the machine body, dial ring and cover glass are installed in the inner body in a throwing manner,
The watch body can be assembled by simply pushing and engaging the outer case from above, and the watch body can be disassembled by simply pushing and removing the outer case from below. Moreover, if the amount of crushing of the rising portion of the outer periphery of the inner case (when clamped) is set appropriately, the watch case can be constructed in a watertight manner, as shown in Figures 4, 5, and 6. The fixing force can also be increased to make the engagement even more secure. Further, the number of components can be reduced, and the shape of the outer shell and glass does not require difficult-to-process groove processing or stepped processing, resulting in a simple shape and low cost. Furthermore, the mechanical body, dial ring,
If the inner shell fitted with glass is considered as a unit, the outer shell can be freely attached and detached even in the market, making it easy to select the shape and color of the outer shell according to requirements and replace it. becomes. Furthermore, since the inner shape of the upper surface of the outer body can be made smaller than the outer shape of the cover glass, the outer circumference of the cover glass can be clearly seen.
この場合、外胴のツバ部内径部下端がカバーガ

ードされるものである。 In this case, since the lower end of the inner diameter of the brim of the outer shell is located on the slope of the outer periphery of the cover glass, when the cover glass is supported by the seam opening on the rising edge of the outer periphery of the outer shell, the cover glass will not come off upward. Despite this possibility, the flange prevents the cover glass from coming off upward, thereby ensuring reliable fixation of the cover glass and, therefore, reliable waterproofing. Moreover, since the upper surface of the flange protrudes upward from the upper surface of the cover glass, the flange protects the watch even when there is a risk of scratches such as impact.
以上に述べた如く、本考案は各部品の形状を簡
単にして、しかも着脱が実に簡単であり外観的に
