View Patent ↗A waterproof component includes a housing body, a mat seal, and a mat seal cover. The housing body includes an attachment-hole-insertion portion having a mat-seal-accommodating chamber, an abutting portion configured to abut a first peripheral surface of the attachment hole, a locking claw provided on an insertion tip side of the attachment hole insertion portion, the locking claw to be locked to a second peripheral surface of the attachment hole, and a cover locking portion provided on an insertion tip side of the attachment-hole-insertion portion. The mat seal has an electric wire press-fitting hole. The mat-seal-accommodating chamber accommodates the mat seal. The mat seal cover locks to the cover-locking portion, the mat seal cover interposes the mat seal between the mat seal cover and a bottom wall of the mat-seal-accommodating chamber. The cover locking portion protrudes from the locking claw in an insertion direction toward the attachment hole.
1. A waterproof component configured to insert an electric wire into an attachment hole penetrating a wall portion to lock, the waterproof component comprising:
a housing body including:
an attachment hole insertion portion configured to be inserted into the attachment hole, the attachment hole insertion portion forming inside a mat seal accommodating chamber having a bottom wall;
an abutting portion configured to abut a first peripheral surface of the attachment hole;
a locking claw provided in an elastically deformable manner on an insertion tip side of the attachment hole insertion portion, the locking claw being configured to be locked to a second peripheral surface of the attachment hole opposite to the first peripheral surface; and
a cover locking portion provided on an insertion tip side of the attachment hole insertion portion;
a mat seal accommodated in the mat seal accommodating chamber, the mat seal having an electric wire press-fitting hole through which an electric wire is to penetrate; and
a mat seal cover locked to the cover locking portion, the mat seal cover interposing the mat seal between the mat seal cover and the bottom wall to hold the mat seal in the mat seal accommodating chamber,
wherein the cover locking portion protrudes from the locking claw in an insertion direction toward the attachment hole.
2. The waterproof component according to claim 1 , wherein
a plurality of the locking claws are arranged at intervals, and
each of the cover locking portion is arranged between the locking claws being adjacent.
