摘要： [Object] To provide a timepiece spring whereby it is possible to ensure high precision and stable operation of precision mechanisms such as timepieces, and to provide a timepiece spring, a mainspring, a hairspring, and a timepiece wherein long-term operation can be ensured when the spring is used as a power source.[Means] A mainspring used as a source to power a drive source is formed from a special titanium alloy and has an S shape when freely spread out, wherein the inflection point at which the curving direction of the freely spread-out shape changes is formed farther inward than the midpoint of an inner end at the end of the winding side and an outer end at the end opposite the inner end. The titanium alloy constituting the present invention has high tensile stress and a low average Young's modulus, making it possible to increase the mechanical energy accumulated in the mainspring 31.

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： An electronic timepiece provided with a generator for self-winding, which is designed to be thinner by improvements of the structure and arrangement of parts, wherein the generator includes a rotor (21) whose shaft (211) is held in a bearing provided with jewels (212, 214) and ring-shaped caps (213, 215). The cap (215) covers the end surface (216) of the jewel (214) which is opposed to the rotor (21) from an outer circumferential side thereof, and forms an annular groove (G3) for a lubricating oil between an inner circumferential surface thereof and an outer circumferential surface of the shaft (211). Accordingly, even when the rotor (21) is rotated at a high speed, the lubricating oil does not scatter from the annular groove (G3) to the surrounding area. This enables various parts to be arranged close to one another, thereby making the electronic timepiece thinner.
摘要翻译：一种具有自动上链发生器的电子钟表，其通过改进部件的结构和布置被设计得更薄，其中发电机包括转子（21），转子（21）的轴（211）保持在设有珠宝的轴承（212,214）和环形盖（213,215）。盖215从其外周侧覆盖与转子（21）相对的珠宝（214）的端面（216），并且在内周面之间形成用于润滑油的环状槽（G3）表面和轴（211）的外周面。因此，即使当转子（21）高速旋转时，润滑油也不会从环形槽（G3）飞散到周围区域。这使得各个部件彼此靠近地布置，从而使电子钟表更薄。
