The present invention relates to sliding parts, precision parts and timepieces and electronic equipment using those parts. Sliding parts are composed by a resin in which the degree of orientation of a fibrous filler is higher at the portion serving as the sliding surface than inside the sliding part, and the fibrous filler is oriented along the sliding surface on the sliding surface. Alternatively, precision parts are composed by a resin to which has been added carbon fibers for which a carbon compound is thermally decomposed to carbon in the vapor phase and simultaneously grown directly into fibers simultaneous to this thermal decomposition. Moreover, timepieces and electronic equipment are composed by these sliding parts or these precision parts.

Sliding parts, precision parts and timepieces and electronic equipment using the same

The invention relates to a timepiece which has a resin bearing section. Moreover, the invention relates to a wheel train apparatus which has a resin bearing section. The invention is constituted by the timepiece provided with a gear wheel and supporting members which support the gear wheel, the supporting members being formed from a filler containing resin. Alternatively the invention is constituted by the wheel train apparatus provided with a gear wheel and supporting members which support the gear wheel, the supporting members being formed from a filler containing resin.

Timepiece, having bearing portion formed of resin and wheel train

The invention relates to a timepiece which has a resin substrate, rotors, and wheel trains, and relates to a wheel train apparatus which has a resin substrate, bearing members, gear wheel, and the like. The invention is constituted by a timepiece comprising; a gear wheel, and a substrate which supports a shaft of a rotor and/or a shaft of the gear wheel, the substrate being formed from a filled resin. Alternatively the invention is constituted by a wheel train apparatus comprising: a gear wheel; a substrate which supports one shaft section of the gear wheel, and a bridge which rotatably supports an other shaft section of the gear wheel, the substrate and the bridge being formed from a filled resin.
