板状部材と軸の固定構造とその固定方法

Fixing structure of plate-shaped member, and shaft and fixing method thereof

Abstract

PROBLEM TO BE SOLVED: To attain a simple and convenient fastening means, without impairing reliability in fixing a plate-shaped member and a shaft member. SOLUTION: This fixing structure of the plate-shaped member and the shaft shaped member comprises the peripheral edge of a fitting small hole in the plate-shaped member has a cylindrical-shaped part, and a conical-shaped recessed part or a wave-shaped part communicating with the cylindrical-shaped peripheral edge part. The end part of the shaft-shaped member is formed with a fitting part, by extending the external diameter of the shaft or forming an offset part, having a smaller diameter. After both of these are fitted, the cylindrical-shaped peripheral edge part and the conical-shaped recessed part communication with the cylindrical-shaped peripheral edge part or the wave-shaped part, having a recessed and projecting part in the front and the back of the plate-shaped member, are pressed by a jig for deformation so as to obtain fixing force.
(57)【要約】 【課題】 本発明は、板状部材と軸部材との固着に係 り、信頼性を損なうことの無い簡便な締結手段を実現す ることを目的とする。 【解決手段】 本発明に成る板状部材と軸状部材の固着 構造は、板状部材の嵌着用小孔の周縁に円筒状形成部を 有すると共に該円筒状周縁部に連通する円錐状凹部もし くは波状形成部を備え、一方軸状部材の端部が軸外径の 伸張もしくは小径段差部として嵌合部が形成され、両者 の嵌合の後、板状部材の円筒状周縁部および該円筒状周 縁部に連通する円錐状凹部もしくは表裏に凹凸を有する 波状形成部を、治具で加圧変形せしめることで、締結固 着力を得るように構成されている。
