Embodiment Construction

[0060] Reference Figure 1 ~ Figure 4 The first embodiment of the present invention will be described.

[0061] Figure 1 ~ Figure 3 Here, reference numeral 11 denotes a timepiece such as a portable timepiece, and specifically, a water-resistant watch. The watch 11 includes a case 12 that constitutes the exterior of the watch 11.

[0062] Such as figure 2 with image 3 As shown, the housing 12 contains the necessary components such as the dial 13, the movement 15, and the display body 17, and the movement 15 controls the movement of the time display hand 14 indicating the time.

[0063] The dial 13 is round and has figure 1 The time shown shows the scale 13a. In addition, the dial 13 may be a digital display type dial that displays a time scale on a liquid crystal screen. The time display hand 14 is composed of at least an hour hand and a minute hand among the hour hand, minute hand, and second hand.

[0064] Such as figure 1 As shown, the handle 16 is mounted on the housing 12 in ...

Abstract

Provision of a timepiece which, although it can suppress a malfunction of the display body in the case, can lightly rotate the operation member causing the display body to operate in conjunction therewith, and which exhibits high level of reliability in waterproof performance around the operation member. To a case 12 to which a pipe 28 is fixed, there is mounted an operation member 41 conjunction-moving a display body 17 in the case 12 so as to be movable between an operating position and a setting position. One of the pipe 28 and a shaft portion 43 of the operation member 41 inserted into the same has a first annular contact surface 29, and a second annular contact surface 30 forming a diameter different from the diameter that the contact surface 29 forms, and an annular slope 31 extending between these contact surfaces. The other has an annular opposing surface 44 opposite each of the above surfaces. A packing 48 capable of elastic deformation and configured to effect waterproofing between the pipe 28 and the shaft portion 43 is mounted to the other so as to protrude from the annular opposing surface 44. At the operating position, the packing 48 is brought into contact with the annular contact surface forming a wide gap between itself and the annular opposing surface 44, and, at the setting position, the packing 48 is brought into contact with the annular contact surface forming a narrow gap between itself and the annular opposing surface 44.

Description

Technical field [0001] The present invention relates to a timepiece such as a portable timepiece having a display body in a casing constituting an exterior, wherein the display body is moved by an operation outside the casing. Background technique [0002] Heretofore, there are known timepieces equipped with the following components: an inner rotating ring, which is arranged to be able to rotate along the periphery of the dial in the outer casing; and an operating member, which rotates the ring from the outside of the outer casing (for example, see Literature 1.). [0003] In the timepiece of Patent Document 1, the operating member linked to the inner rotating ring has: a shaft portion that penetrates a tube fixed to the outer casing; and a head for rotating operation that is continuous with the shaft portion and is arranged on the outer casing The outside of the housing. The inner diameter of the tube does not change and is constant, and the outer diameter of the shaft portion i...
