摘要:
In an electronic timepiece, a baseplate having a pair of opposed major surfaces, a magnetic shield plate disposed in continuous contact with one of the major surfaces and a stator disposed on the other of the major surfaces. A pin is inserted through the magnetic shield plate, baseplate and stator and includes a head portion bearing against the magnetic shield plate, and is engaged by a screw having a head bearing against the stator for fixing the shield plate, baseplate and stator between the head portion and the screw head. The shield plate includes an inwardly sloped aperture for receiving the head portion of the pin, and the head portion has a tapered peripheral surface complementary to the inwardly sloped surface of the aperture. The head portion is thinner than the shield plate and does not protrude beyond a surface of the shield plate, and because the shield plate is in continuous contact with the base plate it is not deformed by the head portion of the pin bearing thereagainst.
