Grommet opening/closing apparatus and method for passing wiring harness through grommet by using the same

Abstract

A grommet opening/closing apparatus includes one opening/closing device and the other opening/closing device. Both opening/closing devices are arranged oppositely against each other, each having a plurality of hooks and a driving unit to open and close the plurality of hooks. A base portion of the plurality of hooks of the one opening/closing device expands and returns one end of a grommet, and a base portion of the plurality of hooks of the other opening/closing device expands and returns the other end of the grommet. One end of the grommet is held by half-opening the hooks of the one opening/closing device, the closed hooks are inserted in the other end of the grommet. Thereafter, the hooks of both opening/closing devices are completely opened, and the wiring harness is passed through the grommet.

Dependencies are inferred from the claim text.
