転リングの逆回転防止構造。 The engaging part of the rotating ring is rotatably loosely fitted into the engaging part provided on the upper outer circumferential part of the body, and a number of ratchet grooves formed on the inner wall of the rotating ring and the outer circumferential part of the body below the engaging part are connected to each other. A ring-shaped linear spring is disposed between the rings and follows the outer circumference, and the tip of the linear spring is brought into elastic contact with the groove of the ratchet, so that the rotary ring can be rotated with an appropriate moderation. In the structure of the rotating ring of the case, the ratchet groove is composed of at least two slopes formed in a substantially mountain shape, and the tip of the linear spring connects the slopes with two slopes that substantially coincide with the slopes. A timepiece comprising an upper flat surface, a gap is formed between the upper flat surface and the ratchet groove, and a dredged part is formed on the outer periphery of the body over a length corresponding to at least 90 degrees from the tip of the linear spring. Structure to prevent reverse rotation of rotating ring.
