- Specific application methods include application with a brush and application with a sponge.
- the gear core forming step is preferably performed before the tooth portion forming step.
- the gear core that occupies most of the gear volume has already been shrunk and solidified by the previous injection molding, and the tooth portion that is the remainder of the gear is injection-molded on the outer periphery of the gear core. For this reason, the gear core is hardly contracted, and the dimensional accuracy is determined by contraction of the tooth portion having a smaller volume compared to the gear core, so that a gear having a higher dimensional accuracy can be easily obtained.
- the gear core body and the tooth portion are formed of a polyamide resin
- the gear core body may be formed by extrusion molding, compression molding, cutting, or the like in addition to injection molding. In this case, after placing the joint of the outer periphery of the gear core obtained by extrusion molding with a bonding aid in the mold, the tooth portion is injection molded. It ’s fine.

- the gear manufacturing method described above it is advantageous in terms of the number of manufacturing steps that the tooth portion is formed by injection molding every time. However, particularly when dimensional accuracy is required, the injection molding is performed. You may finish the teeth later. Of course, a tooth part may be roughly formed at the time of injection molding, and then the tooth part may be formed by gear cutting.
- the molding shrinkage compared to the conventional polyamide resin tooth rate that is integrally formed from the beginning. It can suppress the adverse effects caused by and has high dimensional accuracy.
- the bonding resin containing a specific component is applied to the outer periphery of the gear core or the inner periphery of the tooth portion, so that the polyamide resin on the outer peripheral surface of the gear core or the inner peripheral surface of the tooth portion is reduced.
- the surface is modified slightly by the bonding aid, and then the two are bonded together.
- the gear core body and the tooth part are joined with higher joint strength than before.

- this gear performs the above-described action.
- the outer periphery or tooth portion of the gear core body is reduced by the reducing action of the component (A).
