PROBLEM TO BE SOLVED: To provide a caulking technology which can lay out attachment holes which are formed at a base body in order to attach an electromagnetic valve or the like thereto by making them approximate each other, and can improve the durability of a caulked portion.SOLUTION: As shown in Fig. (b), a caulking jig 60 comprises: a truncated cone point tip 61; a folded part 63 which is formed while gradually being contracted in a diameter toward the other end side from the tip 61 at the inside of a radial direction (center axis 62 side in Fig. (a)), and pushes aside a thickness of an opening edge 57 to the inside of the radial direction; and a pushing/fixing part 64 which is formed inside the radial direction rather than the folded part 63 substantially in parallel with the opening edge 57, and pushes and fixes the thickness which is pushed aside by the folded part 63.EFFECT: Since a caulking load is not applied to the outside of the radial direction, even if, for example, the attachment holes adjoin each other, a degree of freedom of a layout of the attachment holes can be enhanced without exerting influences to the adjacent attachment holes.SELECTED DRAWING: Figure 4
【課題】電磁弁などを取付けるために基体に形成される取付穴同士を接近してレイアウトすることができるとともに、かしめ部分の耐久性向上を図ることができるかしめ技術を提供する。【解決手段】図(b)に示すように、かしめ治具60は、尖り先の先端部61と、径方向内側(図(a)中心軸62側)に先端部61から他端側に向かって漸次縮径して形成され、開口縁部57の肉を径方向内側に押し寄せる折り曲げ部63と、この折り曲げ部63よりも径方向内側に、開口縁部57と略平行面に形成され、折り曲げ部63により押し寄せられた肉を押し固める押し固め部64とを備える。【効果】かしめ荷重が径方向外側に掛かることがなくなるので、例えば取付穴同士が隣接していても、隣接する取付穴に影響を及ぼすことなく、取付穴のレイアウトの自由度が高められる。【選択図】図4
