Title: GROMMET AND WIRE HARNESS WITH GROMMET
Abstract:
The purpose of the present invention is both to minimize the force necessary to mount a grommet in a mounting hole, and to maximize the retention force in a state in which the grommet has been mounted in the mounting hole. This grommet is provided with a grommet main body formed from an elastic material, and an inner member. The grommet main body comprises a cylindrical portion, and a large-diameter portion which is formed extending from the cylindrical portion towards the outer periphery and which comprises an annular portion formed in the outer peripheral portion so as to be capable of being arranged in the inner periphery of the mounting hole, and the grommet main body is fitted into the mounting hole from one end in the axial direction of the large-diameter portion. The inner member is arranged inside of the annular portion and can change states from an initial state to an expanded-diameter state elastically expanding the diameter of the annular portion.
