Grommet and grommet-equipped wire harness

Abstract

There is provided a grommet with water-blocking performance improved by suppression of deformation of a rear end caused by deformation of a fastening fixing portion. The grommet includes: a rear band mounting portionwhich fastens and fixes a portion displaced from the rear end and overlapping a corrugated tubefitted in the grommet by using a band-shaped binding band; and a plurality of rear end-side annular protruding portion, first fixed-side annular protruding portion, and second fixed-side annular protruding portionprotruding from an inner peripheral face and extending in a circumferential direction and disposed along a front-rear direction X so as to be fitted with the corrugated tubeby use of protruding and recessed shapes. The rear end-side annular protruding portionis disposed close to the rear end, the first fixed-side annular protruding portionand the second fixed-side annular protruding portionare disposed at a predetermined interval on an inner peripheral face of the rear band mounting portion, and a highly deformation absorbable portionhaving higher deformation absorbing performance than the rear band mounting portionis provided between the rear end-side annular protruding portionand the first fixed-side annular protruding portion
