Latest Patents

One of Kawatani's latest patents is a fastening structure that includes a bolt with a serration designed to be press-fit into a bolthole of a flange. This invention aims to prevent deterioration in the flatness of the surface of a flange portion when the serration of the bolt is press-fit into it. The design specifies that one portion in the axial direction of the outer peripheral surface of the bolt is equipped with the serration. The bolt is press-fit into a bolthole formed through the flange portion of a mounting member. The serration is strategically located apart from the respective end surfaces of the flange portion by first and second distances, which each exceed 13% of the thickness of the flange portion. This arrangement ensures that the serration presses against the bolthole's inner peripheral surface only in regions far from both end surfaces of the flange portion.
