Embodiment Construction

[0040] Below, according to Figure 1 to Figure 18 Typical embodiments of the present invention will be described. Gromet G is used for the fixing structure of this embodiment. Typically, this fixing structure is used in the following cases. A single fixing object M has a through hole Ma of a size that the head 1 of the hole G cannot enter but allows the foot 2 of the hole G to pass through. 2 After being inserted through the through-hole Ma of the fixed object M, a shaft P (pin) described later that is pushed in from the head 1 side pushes the leg 2 from the inside by the shaft P and utilizes the elasticity. It deforms and expands, sandwiches and fixes the above-mentioned fixed object M stacked between the leg portion 2 and the head 1 on the fixed object M, and closes the through hole Ma. Or, in particular, this fixing structure is used to: from the state where two or more fixing objects M are stacked in a manner communicating with the through hole Ma, after the above-mentio...

Abstract

Disclosed is an attaching structure wherein a grommet comprises a head and a leg and the leg of the grommet is inserted into a through hole generated in an object and thereafter the leg is dilated by a shaft pressed in from the head side, thereby clamping the object between the leg and the head to attach to the object. The leg of the grommet is divided into a plurality of sections by slits generated along the direction of pressing in the shaft, and projecting sections which enter the slits generated in the leg of the grommet and allow the insertion of the leg are formed at the edge of the through hole generated in the object. Each of the projecting sections has a size nearly equal to or a little larger than the width of each slit.

Description

technical field [0001] The present invention relates to improvements in fastening structures using eyelets. Background technique [0002] There are eyelets called pin eyelets and the like. (Refer to Patent Document 1) The eyelet includes a hollow leg portion inserted through a through hole of the object to be fixed, and a head portion of a size that does not enter the through hole. A hole communicating with the inside of the foot is opened on the head. In addition, the eyelet is configured such that, from the state where the foot is inserted through the above-mentioned through hole, the pin is completely pushed into the foot through the hole in the head, so that the foot is expanded by elastic deformation, and the expanded foot and the foot are connected to each other. The fixed object is sandwiched between the heads and fixed on the fixed object. [0003] From the point of view of easier fixing work using this eyelet, it is desirable that the eyelet not be completely pus...
