[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boss clip which is fitted to and attached to a boss and covers the boss, and is suitable for fixing a garnish or a carpet of an automobile.

[0002]

2. Description of the Related Art Conventionally, garnishes and carpets have been installed in the interior of a vehicle or the like for the interior of the vehicle. For this reason, for example, in order to continuously fix a plurality of garnishes in the vehicle interior, a screw shaft or a boss is formed in one garnish, and the screw shaft or the boss is inserted into a hole formed in the other garnish. Are known.

As a conventional structure for fixing a garnish with a screw shaft, there is known a structure in which a key-shaped synthetic resin claw is formed in a bolt cap, and the claw is engaged with and engaged with the screw shaft. (Japanese Utility Model Laid-Open No. 63-51915).

FIG. 10 shows a conventional garnish in which a garnish is fixed by a boss. That is, when a boss is used, a boss 104, which is a pin protruding from the lower garnish 102, is inserted into a hole 108 formed in the upper garnish 106 in order to appropriately generate a locking force, and a circular tubular shape is formed. With a jig 110, a push nut 112 made of metal and made in a dish shape as shown in FIG. 11 was pushed into the front end side of the boss 104.

[0005]

In the conventional structure in which the garnish is fixed by the screw shaft, the structure of the bolt cap itself is complicated, and the claw engaging with the screw shaft is made of synthetic resin. It had the disadvantage of being weak.

On the other hand, in a conventional structure in which a garnish is fixed by a boss, a push nut 112 is
Is fitted to the boss 104 to join the garnishes 102 and 106 together. However, since the push nut 112 is exposed to the vehicle interior side, not only the appearance is poor, but also the push nut 112 cannot be manually inserted. Therefore, there is a disadvantage that workability is poor. In addition, it is difficult to remove the push nut 112 once fitted, and there is a disadvantage that the labor is excessive when it becomes necessary to remove the push nut 112 for repair or the like.

If the outer diameter is increased, the push nut can be manually attached without using a jig. However, not only the appearance is further deteriorated, but also the workability in removing the push nut is increased. Does not lead to improvement.

The present invention has been made in consideration of the above-described circumstances, and has as its object to provide a boss clip that firmly engages with a boss and that can be easily attached to and removed from the boss.

[0009]

According to the boss clip of the present invention, the tip is formed obliquely so as to intersect with a plane perpendicular to the axial direction of the boss, and the tip abuts on the boss to provide an elastic force. A metal engaging portion for locking the boss with a base, a base having a hole into which the boss is inserted, and incorporating the engaging portion so that the engaging portion is located in the hole; and a base connected to the base. And a rotating portion formed with a joining portion between the tool and the tool that rotates the base portion.

[0010]

The base has a hole into which the boss is inserted, and the base has a built-in engaging portion that abuts against the boss and locks the boss with elastic force. The tip of the engaging portion is formed obliquely so as to intersect a plane orthogonal to the axial direction of the boss.
Further, a turning portion is connected to the base portion, and a joint portion between the turning portion and a tool for turning the base portion is formed.

As described above, for example, when a boss is inserted into the hole of the base by manual operation or the like, the boss is locked by the engaging portion that comes into contact with the boss. In this case, since the base has the engaging portion, the base can be easily grasped for the insertion operation. On the other hand, when removing the boss from the hole, the tool is joined to the joining portion, and the tool is rotated to rotate the rotating portion and the base connected to the rotating portion. Therefore, the engagement portion rotates around the boss together with the base. As a result, the distal end of the engaging portion is formed obliquely so as to intersect with a plane orthogonal to the axial direction of the boss, and the distal end of the engaging portion bites into the boss with elastic force. The engagement part spirally rotates around the boss,
The engaging portion is removed from the boss.
