Waterproof clip

摘要

Bulging portions elastically coming into contact with an inner peripheral surface of a fixation hole of a panel member are formed on an outer peripheral surface of a shaft portion of a waterproof clip made of an elastic material, thereby sealing a space between these surfaces by elasticity of the bulging portions to obtain a waterproof function, and firmly fixing the shaft portion to the panel member by friction force between the inner peripheral surface and the bulging portions. The clip requires no special seal member, thereby reducing the number of parts and assembly steps. Each bulging portion is formed narrower toward the front side in the insertion direction of the shaft portion, thereby easily press fitting the shaft portion into the fixation hole while improving waterproofness and airtightness by sufficiently compressing the bulging portions. The clip can surely fix an interior material to the panel member with excellent sealability.

主权项

1. A waterproof clip made of an elastic material, configured for fixing an interior material to a panel member, the waterproof clip comprising:
a shaft portion that is configured to penetrate a through-hole of the interior material and is configured to be press-fitted to a fixation hole of the panel member; and a plate portion provided at a rear end of the shaft portion in an insertion direction thereof and configured to come into contact with a surface of the interior material, wherein the shaft portion comprises a main body portion which is located on a rear end side in the insertion direction, and a tapered portion which is located on a front end side in the insertion direction and whose diameter becomes smaller from the main body portion, and the tapered portion is substantially solid, a number of bulging portions which are configured to elastically come into contact with an inner peripheral surface of the fixation hole are formed on an outer peripheral surface of the main body portion, each of the bulging portions is formed to become narrower toward a front side in the insertion direction of the shaft portion and a hollow portion is formed in an inner portion of the main body portion, the hollow portion being open to the plate portion and extending to a position near a rear end of the tapered portion in the insertion direction.
