The present invention relates to a fastener for restraining attachment members to each other.

BACKGROUND ART [0002] Conventionally, for example, grommet described in Patent Document 1 below is used when restraining a mounting member such as a bumper or an under cover of an automobile to a vehicle body. This grommet is composed of a shaft body and a body into which the shaft body is inserted. The shaft body is formed with a plurality of grooves as engaging portions. On the other hand, the main body is provided with a to-be-engaged portion protruding from the edge of the hole into which the shaft is inserted toward the center of the hole, and a leg piece protruding downward from the edge of the hole is formed. When the shaft body is inserted into the main body, the engageable portion and the leg piece are pushed in a direction intersecting the insertion direction by the shaft body, and the engaged portion and the leg portion of the main body are engaged with the engaging portion of the shaft body. In other words, the grommet is engaged with the engaging portion of the shaft body at two positions, i.e., the upper and lower positions, by the engaged portion and the leg piece.

According to this grommet, when the fitting member is restrained to the vehicle body, the leg piece of the body is disposed inside the vehicle body when the body into which the tip end of the shaft body is inserted is fitted into the mounting hole of the fitting member superimposed on the vehicle body. In this state, when the shaft is further pushed into the inside of the body, the grommet is widened outward from the inside of the body of the leg piece of the body. In this manner, the grommet restrains the fitting member to the vehicle body by sandwiching the vehicle body and the fitting member into the body and the shaft body.

Patent Document 1: Japanese Patent No. 5627940

However, the above-mentioned grommet has a short engagement portion and a shallow engagement degree, so that the shaft body may be easily detached from the main body. If the portion to be engaged is long, it is necessary to increase the extent to which the engaged portion is widened when inserting the shaft body into the main body, and the main body becomes large in the direction in which the engaged portion is pushed.

The present invention has been proposed in view of such circumstances. That is, it is an object of the present invention to provide a fastener which can firmly fix a degree of engagement.

In order to attain the above object, a fastener according to the present invention includes: a male member having an axial leg portion formed below a head portion; a flange portion formed at an edge of an opening portion into which the axial leg portion is inserted, (Female member) having a leg portion formed facing toward the flange portion, wherein one of the engaging portion and the engaged portion engaging each other is formed on each of the head portion and the flange portion, and the male member and the female member are combined Wherein the engaging portion is provided with a locking piece portion protruding toward the head portion or the flange portion with the engaging portion formed thereon, a locking protruding portion formed at the tip of the locking piece portion, And the engaging portion is provided with an insertion hole of the shaft leg portion on the axis of the support shaft portion, And a direction crossing characterized in that the elastic deformation.

That is, when the shaft leg portion of the male member is inserted into the opening portion of the female member and the male member and the female member are combined, the female screw portion is pushed by the shaft leg portion. Here, since the engaging piece portion is projected toward the head portion or the flange portion where the engaging portion is formed and the base side is supported by the support shaft portion, the position of the base side is not changed when elastic deformation occurs, And is pushed in a direction intersecting with the insertion direction of the part. That is, it is possible to firmly fix the arm member by deepening the degree of engagement by the engagement projection without changing the size of the arm member to the direction in which the arm member is pushed and expanded.

In addition, since the support shaft portion is twisted, the engagement portion is expanded by being pushed, so that the engagement portion is likely to be elastically deformed.

According to the fastener according to the present invention, the base side of the fastening portion is connected to the support shaft portion and the periphery thereof is hollow. That is, the engaging portion is hollow and is connected to the support shaft portion so as to be hollow. When the engaging portion is elastically deformed, the supporting shaft portion is twisted, and the engaging portion is pushed in the direction intersecting the inserting direction of the shaft leg portion about the supporting shaft portion to engage with the engaging portion. Therefore, the degree of engagement can be deepened and fixed firmly. Since the periphery of the base side is hollow and the base side is supported at two points on both sides, the engaging portion is hollow and the base side is easy to move.

With this configuration, even when foreign matter such as gravel is caught between the shaft leg portion and the leg portion, the foreign matter slips on the flat side surface, so that the foreign matter is prevented from being caught.

Even if the degree of elastic deformation of the leg portion is weakened by the creep, the side surface of the leg leg portion facing the inside of the leg portion is flat, and the shaft leg portion and the leg portion are not engaged with each other. It does not affect the degree of engagement. That is, the leg portion subjected to the creep does not engage, but the male member and the female member are combined by engaging the engaging portion protruding toward the head portion or the flange portion with the engaged portion, so that the influence of the creep is avoided .

The fixture according to the present invention is constituted by a temporarily fixed portion to be engaged formed on the lower side of the shaft leg portion and a main fixed portion to be engaged formed on the side of the head portion. According to this configuration, the engaging portion engages with the temporarily fixed engaging portion of the shaft leg to engage the engaging portion with the main fixation engaging portion of the shaft leg, whereby the engaging portion is held in the main fixed state do. Therefore, the male member and the female member can be combined and handled in a temporarily fixed state, so that the performance of the mounting operation can be improved.
