Abstract

A fastener includes: a first leg part; a second leg part; a coupling part coupling one ends of the first leg part and the second leg part; a first head part and a second head part which are provided with a flange for engaging with a front-side edge of an attachment hole, and a pressing surface for a user to press, and which are provided to other ends of the first leg part and the second leg part; and a screw hole formed in the second head part, and into which a screw member is screwed. The first leg part includes a first engagement part capable of engaging with a rear-side edge of the attachment hole. The second leg part includes a second engagement part capable of engaging with the rear-side edge of the attachment hole.

First claim

The invention claimed is:

1. A fastener that is attached to a mounting hole of a first member and to which a second member is attached using a screw member, the fastener comprising:
a first leg portion having elasticity;
a second leg portion having elasticity, and being provided to be opposed to the first leg portion;
a connecting portion connecting one end of the first leg portion and one end of the second leg portion;
a head portion comprising:
a flange to be engaged with an edge of the mounting hole on a top side thereof; and
a pressing surface to be pressed by a user, the head portion being disposed on other ends of the first leg portion and the second leg portion so as to be opposed to the connecting portion; and

a screw hole portion into which the screw member is screwed, the screw hole portion being disposed in at least one of the connecting portion and the head portion,
wherein the first leg portion comprises a first engagement portion engageable with an edge of the mounting hole on a back side thereof,
wherein the second leg portion comprises a second engagement portion engageable with the edge of the mounting hole on the back side thereof,
wherein the head portion comprises:
a first head portion extending from the first leg portion; and
a second head portion extending from the second leg portion so as to overlie the first head portion,

wherein, when the first leg portion and the second leg portion approach with each other, the first head portion and the second head portion relatively move in a state where the first head portion and the second head portion overlie with each other,
wherein the first leg portion comprises a first sandwiching portion extending toward the second leg portion,
wherein the second leg portion comprises a second sandwiching portion extending toward the first leg portion, and
wherein the first sandwiching portion and the second sandwiching portion are expandingly opened by abutting the screw member inserted into the screw hole portion, or prevented from approaching with each other by abutting on the screw member.

2. The fastener of claim 1 , wherein the first head portion extends from a distal end of the first leg portion toward the second leg portion,
wherein the second head portion extends from a distal end of the second leg portion toward the first leg portion, and
wherein one of the first head portion and the second head portion comprises the screw hole portion, and an other one of the first head portion and the second head portion comprises an insertion hole for the screw member inserted into the screw hole portion.

3. The fastener of claim 2 , wherein the first head portion overlies the second head portion on a top side, and comprises the insertion hole that has a diameter larger than a diameter of the screw hole portion.

4. The fastener of claim 3 , wherein the first head portion has a size larger than the second head portion so as to prevent the second head portion from lying off the first head portion when the fastener is inserted into the mounting hole.

5. The fastener of claim 3 , further comprising:
a slit arranged to divide a hole edge that defines the screw hole portion in a circumferential direction.

6. The fastener of claim 5 , wherein the second head portion comprises plural protruding portions protruding toward the connecting portion, and
wherein the plural protruding portions are arranged to protrude into the mounting hole when the fastener is attached to the first member.

7. The fastener of claim 1 , wherein, as being expandingly opened by insertion of the screw member, the first sandwiching portion and the second sandwiching portion are engaged with a hole edge of the mounting hole on the back side.

8. The fastener of claim 2 , wherein the second head portion comprises a concave portion more recessed toward the connecting portion than the flange, and
wherein the first head portion is disposed to overlie the concave par n thereabove on a top side of the second head portion.

9. A fastener that is attached to a mounting hole of a first member and to which a second member is attached using a screw member, the fastener comprising:
a first leg portion having elasticity;
a second leg portion having elasticity, and being provided to be opposed to the first leg portion;
a connecting portion connecting on end of the first leg portion and one end of the second leg portion;
a head portion comprising:
a flange to be engaged with an edge of the mounting hole on a topside thereof; and
a pressing surface to be pressed by a user, the head portion being disposed on other ends of the first leg portion and the leg portion so as to be opposed to the connecting portion; and

a screw hole portion into which the screw member is screwed, the screw hole portion being disposed in at least one of the connecting portion and the head portion,
wherein the first leg portion comprises a first engagement portion engageable with an edge of the mounting hole on a back side thereof,
wherein the second leg portion comprises a second engagement portion engageable with the edge of the mounting hole on the back side thereof,
wherein the head portion comprises:
a first head portion extending from first leg portion; and
a second head portion extending from the second leg portion so as to overlie the first head portion,

wherein, when the first leg portion and the second leg portion approach with each other, the first head portion and the second head portion relatively move in a state where the first head portion and the second head portion overlie with each other,
wherein the first head portion extends from a distal end of the first leg portion toward the second leg portion,
wherein the second head portion extends from a distal end of the second leg portion toward the first leg portion,
wherein one of the first head portion and the second head portion comprises the screw hole portion, and an other one of the first head portion and the second head portion comprises an insertion hole for the screw member inserted into the screw hole portion, and
wherein the second head portion overlies a back side of the first head portion, and is inclined such that a distal end of the second head portion is apart from the first head portion.
