Abstract:
1. A grommet including a small diameter tubular section and a large diameter tubular section contiguous with said small diameter tubular section, both of said tubular sections configured to be attached to a wire harness for a motor vehicle by threading said wire harness through both of said tubular sections, said small diameter tubular section configured to be inserted into a through-hole in a vehicle body panel, said large diameter tubular section being provided on an outer peripheral surface with a vehicle body engagement annular recess, and said recess configured to be engaged with said vehicle body panel; said large diameter tubular section being provided on the outer peripheral surface with a plurality of projecting portions that extend from a connecting part between both of said tubular sections to a slant wall of a side wall of said vehicle body engagement annular recess in an axial direction of said large diameter tubular section and are spaced from one another in a peripheral direction of said large diameter tubular section; and each of said projecting portions including a contact point that initially contacts with an inner peripheral surface around said through-hole upon inserting said grommet into said through-hole, a bending point above said contact point, a distal end point at a side of said vehicle body engagement annular recess, and a proximal end point at said connecting part, each of said projecting portions including an increasing diameter directing slant portion that extends from said proximal end point through said contact point to said bending point in parallel to the outer peripheral surface of said large diameter tubular section, and a decreasing diameter directing slant portion that extends from said bending point to said distal end point at a side of said vehicle body engagement annular recess and inclines in a reversed slant direction, a distal end of said decreasing diameter directing slant portion being disposed at said distal end point protruding from said slant wall, and said slant wall being disposed between said distal end of said decreasing diameter slant portion and a groove bottom surface of said vehicle body engagement annular recess.
