Abstract

Provided is a fastener with each elastic locking piece which can not be broken even when an impact is applied on by forming a joint part of a synthetic resin passed through a post part and the synthetic resin passed through a plurality of elastic locking piece parts in a head. In the fastener 1, a post 21 is vertically provided on the head 11 in a lower side, the plurality of the elastic locking pieces 31 having a swelling part 33 outside in the middle in a vertical direction are vertically provided in the lower side of the head 11, and respective lower end parts of the plurality of the elastic locking pieces 31 are connected with the lower end part of the post 21. The volume of the head 11 is made to be not less than three times and not more than five times of that of the post 21, the volume of the post 21 is made to be the same as the total volume of the plurality of the elastic locking pieces 31, and a gate is provided on a lower end of the post 21.

Description

technical field [0001] The invention relates to a clamping part used in the case of clamping components installed in automobiles or electric appliances on the panels of the car body or the main body of the electric appliances, or installing other panels on the panels. Background technique [0002] In the above-mentioned clamping parts in the past, the pillars are vertically arranged on the lower side of the head, and a plurality of elastic fastening pieces are vertically arranged on the lower side of the head. At the same time, the lower end of a plurality of elastic fastening pieces is connected to the lower end of the pillar. In addition, at the boundary between the head and the pillar, an elastic sealing part is also provided on the lower side of the head of the outer periphery of the pillar, and is made of synthetic resin. Made of material (for example, refer to Patent Document 1-Japanese Patent Laying-Open No. 5-164120, paragraphs [0011] to paragraphs [0019], figure 1 ...
