发明名称 TIMEPIECE
摘要 <p>PROBLEM TO BE SOLVED: To provide a timepiece which can maintain the reliability for holding a state where a bezel is attached to a body, and allows backlash of the bezel and rotational operation torque to be restricted without using a dedicated packing material.SOLUTION: An engagement projection 33 extending in a circumferential direction is formed on the outer periphery of an annular projecting portion 31 which a body 21 has. A bezel 41 includes an inner peripheral recessed portion 44 surrounding the outer periphery of the annular projecting portion 31. An attachment member 51 includes an outer peripheral portion 52 disposed in the inner peripheral recessed portion 44, an inner peripheral portion 54 continuous to the outer peripheral portion 52, and an engagement part 56 formed on the inner peripheral portion 54. The inner peripheral portion 54 can be elastically deformed in such a direction as to come into contact with and separate from the outer peripheral portion 52, by an annular groove 59 formed between the inner peripheral portion 54 and the outer peripheral portion 52. The engagement part 56 can be engaged with and disengaged from the engagement projection 33 in accordance with elastic deformation of the inner peripheral portion 54. In a state where the bezel 41 is disposed so that it covers the outer periphery of the annular projecting portion 31 and can be rotated, an engagement state between the engagement projection 33 and the engagement part 56 is maintained by elastic force of the inner peripheral portion 54.</p>
