Claims

[Scope of utility model registration request]

The protrusion and the fitting part on the shaft mounting body have the same radial cross-section shape, and the contour line consisting of the external tangent line of the protrusion and the internal tangent line of the fitting part has the same square shape as the square hole at the center of the disc-shaped gear. They are arranged symmetrically about the multiple axis, and a shaft hole surface is provided on the inscribed line side of the protrusion, and the pair of shaft mounting bodies are attached to the disc-shaped gear, and both protrusions are passed through the square hole from opposite directions. The disk-shaped gear is tightly connected to the mating portions on the opposite sides to rotate integrally, and the shaft is inserted integrally into the shaft hole formed by the shaft hole surface portion of each protrusion. Bearing structure for disc-shaped gears.
