Abstract

PURPOSE: To reduce the thickness of a watch case by pressing an annular packing by both a body with peripheral oblique groove and a back cover having an oblique surface on the outside surface to thereby clamp a back cover.
CONSTITUTION: A synthetic resin annular packing 3 is mounted on the stepped portion 1a of a body 1, and the upper peripheral ridge 2d of a back cover 2 is engaged with the inner peripheral guide oblique surface 3a of the packing 3. Thus, the cover 2 is press-fitted into the body 1. When the back cover 2 is thus press- fitted, the packing 3 is expanded toward the peripheral groove 1c to thereby fill a gap S, and strongly pressed by both the oblique surface 1c' of the peripheral groove 1c, the outer surface 2d of the back cover 2 and the outer peripheral oblique surface 2c to thereby clamp the back cover 2 by the pressing force.
