Patent number: 8371789Abstract: While a high pullout force is being achieved, when a hole plug is demolded from a mold, a load on a locking claw is reduced. A leg portion 3 of a hole plug 1 includes an inner tube 11, an outer tube 12 surrounding the inner tube, ribs 15 interconnecting the inner and outer tubes, and locking claws 14 provided on an outer circumferential surface of the outer tube and locked in a circumferential border thereof when the leg portion is inserted into a hole 22 of a body panel 21. The ribs are disposed corresponding to positions of the locking claws, and are structured so as to be tilted relative to a radial direction of the hole plug in a case of being viewed from an insertion direction of the leg portion.Type: GrantFiled: October 7, 2009Date of Patent: February 12, 2013Assignee: Nifco Inc.Inventor: Takashi Takita
