Abstract

PURPOSE: To enable the mass production of a bobbin which has a high dimensional accuracy and is not damaged, by making a male and a female molds according to the inside and outside forms of the bobbin and injecting a molding material in between the molds to integrally form the bobbin.
CONSTITUTION: The bobbin 7 or 42a for a hollow arc-shaped moving member 42, which swings along an arc centering a shaft 2 in an arc-shaped stator 41, is integrally made from the molding material. The male and the female molds corresponding to the inside and outside forms of the bobbin 42a are previously manufactured. The molding material such as epoxy resin is injected in between the molds to integrally form the bobbin. A reinforcing material such as non-metal fibers is wound around the male mold and molded with the molding material so that the bobbin is reinforced. This enables the mass production of the bobbin of high dimensional accuracy and durability.
