摘要: A winding stem (10) is connected to an inner end (11a) of a mainspring (11), and an outer end (11b) of the mainspring (11) is connected to a barrel drum (12). A braking plate (15) is placed inside a braking case (14), and the braking case (14) is filled with a fluid (16). An uneven joint portion (10b) is formed at the lower end of the winding stem (10), and is engaged with an uneven joint portion (15b) of the braking plate (15) placed in the braking case (14). By adopting the above configuration which can simplify the structure of the mainspring mechanism having the braking plate and which can reduce the number of components, the size and production cost of the mainspring mechanism can be reduced.
