Abstract
The present invention relates to a pin-type grommet made of synthetic resin. It relates to an improvement of a grommet in which elastic stoppers of a female member are pressed outwardly by press fitting an insertion pin so that the collar and the elastic stoppers of the female member securely hold a plate member, and in which the plate member securely held by the female member is released by screwing out a pin type male member inserted in the female member. More specifically, the present invention relates to a grommet made of synthetic resin in which the male member to be inserted in the female member is provided on its leg with dents which receive the catches of the elastic stoppers, inclined portions which extend upwardly from the dents toward the peripheral surface of the leg, and a portion with larger diameter which presses the elastic stoppers outwardly, the portion with larger diameter being circular in horizontal cross section, and having flat surfaces each with an arcuate side and facing the head of the male member thereby constituting engagement faces for the catches of the female member.
