摘要：
A barrel gear 1 as a driving mechanism of an electronic control mechanical timepiece has a mainspring 1A having a surface of elastic material coated with a film made of DLC thin film. The mainspring 1A has a superior anti-corrosion property and reduced slide resistance while sufficiently securing both of toughness and rigidity on account of the film, so that proportional limit thereof can be increased to increase energy accumulated in the mainspring 1A.
摘要（中）：
作为电子控制机械钟表的驱动机构的桶形齿轮1具有发条1A，其具有涂覆有由DLC薄膜制成的膜的弹性材料的表面。 主发条1A具有优良的防腐性能和降低的滑动阻力，同时充分确保由于膜的韧性和刚性两方面的差异，从而可以提高其比例限制以增加在发条1A中积聚的能量。
