Abstract

A snap structure includes a post, arrowhead-shaped snap pieces, leg pieces, and disengaging pieces. The snap pieces are formed at a distal end of the post and elastically deformable in a radial direction. The leg peices are arranged to oppose the snap pieces. The disengaging pieces are connected each to one end of correcponding one of the snap pieces that are enlarged in diameter, and can reduce in diameter the snap pieces manually. The snap pieces deform elastically in the radial direction, upon insertion in a through hole formed in a chassis or the like, and are fitted in the through hole, so as to clamp the chassis or the like together with the leg pieces. The post includes a stopper portion for prohibiting the post from being inclined in the through hole at not less than a predetermined angle.

Claims

1. A snap structure including:

a post;

arrowhead-shaped snap pieces formed at a distal end of said post and elastically deformable in a radial direction;

leg pieces arranged to oppose said snap pieces; and

disengaging pieces which are connected each to one end of corresponding one of said snap pieces that are enlarged in diameter and which are capable of reducing in diameter said snap pieces manually,

said snap pieces serving to deform elastically in the radial direction, upon insertion in a through hole formed in a chassis, to be fitted in the through hole, so as to clamp the chassis together with said leg pieces,

characterized in that said post comprises a stopper portion for prohibiting said post from being inclined in the through hole at not less than a predetermined angle.

2. A structure according to claim 1, wherein said stopper portion comprises an impact abutting portion which abuts with impact against an inner edge of the through hole (3) when said post is inclined at the predetermined angle, and an abutting portion which abuts against a surface of the chassis when said post is to be inclined at not less than the predetermined angle.

3. A structure according to claim 2, wherein

said post is formed as a plate with a width smaller than a diameter of the through hole,

said stopper portion is formed to project in opposite directions on two sides in a radial direction of said post,

said impact abutting portion is formed in a region in a longitudinal direction of said post which is to enter and be positioned in the through hole when said snap pieces are fitted in the through hole, and

said abutting portion is formed in a region outer than the through hole on an insertion side.
