[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an obturator having excellent mounting workability for closing an opening of a body panel for a vehicle, for example.

[0002]

2. Description of the Related Art As a rubber stopper plug of this kind, FIGS.
The one shown in FIG. 6 is known. As shown in FIGS. 4 and 6, the plug 1 is a flat-elliptical and ring-shaped plug body 2 that abuts on the surface 7 a side of a vehicle body panel (member to be closed) 7. An annular peripheral wall portion 3 integrally formed so as to protrude downward from the lower side of the inner periphery of the body 2, and an engaging portion 3 c integrally formed on the outer peripheral surface 3 b is engaged with the elliptical opening 8 of the body panel 7. And a bottom wall 4 which is formed integrally between lower ends of the annular peripheral wall 3 and also serves as a push wall protruding toward the back surface 7b of the body panel 7 so as to close the opening 8 of the body panel 7. It has.

An operating portion 5 which is pressed when the body panel 7 is attached to the opening 8 is integrally formed substantially at the center of the surface 4a of the bottom wall portion 4 of the obturator 1. In addition, obstruction plug 1
The inner peripheral end of the plug body 2 on the inner peripheral surface 3a of the peripheral wall 3 and the bottom wall 4
A plurality of reinforcing ribs 6 for supporting and reinforcing the bottom wall portion 4 are integrally formed at predetermined intervals.

[0004] The upper surface of the operation portion 5 of the rubber plug 1 is a pressing surface 5a, and when the operator presses the pressing surface 5a with a finger 9, the plug 1 is moved to the body panel 7.
Is mounted in the opening 8 so that the opening 8 is closed. That is, as shown in FIG. 5, the pressing surface 5a of the operation unit 5 of the obstruction plug 1 is
, The bottom wall portion 4 is elastically deformed in a curved shape. As a result, the outer diameter of the annular locking portion 3c of the peripheral wall portion 3 on the front side of the opening 8 of the body panel 7 is reduced, and
c is inserted over the opening 8 and is locked on the back surface 7 b side of the body panel 7.

[0005] A similar technique relating to the plug 1 is disclosed in Japanese Patent Application Laid-Open No. 10-35697.

[0006]

However, in the conventional rubber closure plug 1, since the operating portion 5 on the surface 4 a of the bottom wall portion 4 and each reinforcing rib 6 are separated, the closure plug is not provided. 5 is mounted on the opening 8 of the body panel 7, as shown in FIG. 5, the bottom wall portion 4 between the operating portion 5 and each of the reinforcing ribs 6 extends, and the pressing surface 5a of the operating portion 5 is The pressing force with the finger 9 escaped, and the workability of attaching the obstruction plug 1 to the opening 8 of the body panel 7 was poor.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide an obstruction plug capable of improving the workability of mounting a member to be closed to an opening.

[0008]

According to a first aspect of the present invention, there is provided a stopper body in the form of an annular flange which abuts on the surface side of a member to be closed, and is integrally formed so as to project downward from a lower side of the inner periphery of the stopper body. An annular peripheral wall portion in which an engaging portion formed on an outer peripheral surface is engaged with an opening of the closed member; and an opening formed in the closed member integrally formed between lower ends of the annular peripheral wall portion. A bottom wall which also serves as a push wall protruding to the back side of the closed member so as to close the closed member, and is pressed at substantially the center of the surface of the bottom wall when the closed member is mounted on the opening. And a reinforcing rib for supporting and reinforcing the bottom wall between the inner peripheral end of the plug body and the outer peripheral end of the bottom wall on the inner peripheral surface of the peripheral wall. In an obturation plug integrally formed at predetermined intervals, the operating portion and the reinforcing ribs are separated by connecting ribs. It is characterized by being connected.

In this closure plug, the operating portion and each reinforcing rib are connected to each other by the connection rib, so that when the closure plug is attached to the opening of the member to be closed, the pressing force of the operation portion is applied via each connection rib. It acts directly on each reinforcing rib (that is, on the peripheral wall and the plug body side), and the workability of mounting the plug into the opening of the member to be closed is improved.

According to a second aspect of the present invention, there is provided the closure plug according to the first aspect, wherein the operating portion is integrally formed so as to be substantially cylindrical, and each of the connecting ribs is integrally formed from a surface of the bottom wall portion. The substantially cylindrical operating portion and the reinforcing ribs are integrally connected to each other.

In this plug, each connecting rib is integrally formed so as to protrude from the surface of the bottom wall, and the substantially cylindrical operating portion and each reinforcing rib are integrally connected to each other. When attached to the opening of the above, the pressing force of the substantially cylindrical operating portion directly and efficiently acts on each reinforcing rib (that is, the peripheral wall portion and the plug body side) via each connecting rib, and the substantially cylindrical operating portion Thus, the bottom wall between the reinforcing ribs and the reinforcing ribs does not extend as in the related art, so that the workability of mounting the plug into the opening of the member to be closed is further improved.

When the finger 19 is pressed against the back surface 17 b of the body 7 with the finger 19, the bottom wall 13 is pressed against the opening 18 of the body panel 17 without being elastically deformed in a curved shape as in the related art. As a result, the outer diameter of the annular locking portion 12c of the peripheral wall portion 12 on the front side of the opening 18 of the body panel 17 is reduced, and the locking portion 12c is inserted over the opening edge of the opening 18. And is locked to the back surface 17b side of the body panel 17.

In this rubber plug 10, the peripheral wall 12
Since the auxiliary ribs 14 formed integrally with the inner peripheral surface 12a of the base member 13 and the operation portion 15 on the surface 13a of the bottom wall portion 13 are integrally connected by the connection ribs 16 without being separated from each other, The obturator plug 10 is connected to the opening 18 of the body panel 17.
When it is mounted on the operating portion 15, the bottom wall portion 13 between each reinforcing rib 14 and the operating portion 15 is elastically deformed in a curved shape and does not extend as in the related art, and the pressing surface 15 a of the operating portion 15 is pressed by the finger 19. The pressing force F acts directly and does not escape.

More specifically, each connecting rib 16 is connected to the bottom wall 13.
The reinforcing ribs 14 are integrally formed so as to protrude from the surface 13a of the
When the obstruction plug 10 is attached to the opening 18 of the body panel 17 as shown in FIG. The pressing force F acts directly and efficiently on each reinforcing rib 14 (that is, on the peripheral wall portion 12 and the plug body 11 side) via each connecting rib 16. Thereby, the substantially cylindrical operating section 1
The bottom wall 13 between the reinforcing member 5 and the reinforcing ribs 14 does not elastically deform as in the related art and does not extend in a curved shape.
With the pressing force F of 5, the closure plug 10 can be easily and quickly attached to the opening 18 of the body panel 17, and the workability of attaching the closure plug 10 to the opening 18 of the body panel 17 is further improved. be able to.

In addition, according to the above-described embodiment, the stopper plug made of rubber has been described. However, the stopper plug may be formed of an elastic material such as a thermoplastic elastomer resin.
