Hole plug

摘要

In a case wherein a force acts upward from below on a face plate (34) of a hole plug (14) that is closing an attachment hole (12) of a body panel (10), the face plate (34) is pushed up, and an intermediate wall portion (26) moves upward relative to an outer circumferential wall portion (18). At that time, an outside portion (40B) of an abutment portion (40) is folded inward, and an inside portion (40A) of the abutment portion (40) abuts against an inside face of a lower portion of the outer circumferential wall portion (18). As a result, the inside portion (40A) of the abutment portion (40) can control engagement claws (20) from deforming inward.

主权项

1. A hole plug, comprising:
an annular flange portion for covering a hole edge circumferential face of an attachment hole of an attachment member; a cylindrical outer circumferential wall portion extending downward from an inner circumferential edge portion of the annular flange portion; engagement claws formed to protrude on an outer wall face of the outer circumferential wall portion, for engaging with the attachment hole; a cylindrical intermediate wall portion extended in an up-and-down direction inside the outer circumferential wall portion with an interval therebetween; a cylindrical inner circumferential wall portion extended in the up-and-down direction inside the cylindrical intermediate wall portion with an interval therebetween; a face plate closing an upper-end inside the inner circumferential wall portion; a connection portion connecting the cylindrical intermediate wall portion to a center portion of the inner circumferential wall portion in the up-and-down direction; an abutment portion having an outside portion connected to a lower end of the outer circumferential wall portion, and an inside portion connecting the outside portion to a lower end of the cylindrical intermediate wall portion; and ribs respectively formed along a radial direction of the face plate at portions of the face plate which becomes an inside of the engagement claws, wherein the abutment portion is arranged so that when an upward force is applied to the face plate from below and the face plate moves upward, the outside portion of the abutment portion is bent and is folded inward, and the inside portion of the abutment portion abuts against an inside face of a portion of the outer circumferential wall portion formed with the engagement claw, and the engagement claws are formed at predetermined intervals along a circumferential direction of the outer wall face of the outer circumferential wall portion.
