发明名称 TIMEPIECE MOVEMENT STRUCTURE
摘要 PROBLEM TO BE SOLVED: To provide a timepiece movement structure, coping with a movement having a small diameter, having proper plane positional precision, and superior in reliability. SOLUTION: The structure includes a winding stem spacer 18 having a plane shape in which the position of the plane when a mold is designed is different from the position of the plane when it is molded and a circuit support base 19 having proper precision in the positional accuracy of the plane, wherein an engagement part 22 is provided to a plane part of a peninsula shape 21 deformed when the winding stem spacer is molded, and wherein an engaged part 23 is provided to a circuit support stand. By engaging the engagement part 22 of the winding stem spacer 18 with the engaged part 23 of the circuit support stand 19, the plane part 21 deformed when the winding stem spacer 18 is molded is moved to the correct position in the plane. Accordingly, the problems that the reliability in the plane shape positional accuracy is not proper and that the winding stem spacer having a complicated shape cannot be securely held and fixed to the timepiece sheathing, because a sink, warpage, deformation due to the separation from the mold, or the like arises at the time of molding.
