Title: Kazuhisa Yama: Innovator in Automotive Fastening Technology

Introduction

Kazuhisa Yama is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of automotive technology, particularly in fastening mechanisms. His innovative approach has led to the development of a unique fastening member that enhances the attachment of compressors to vehicle bodies.

Latest Patents

Kazuhisa Yama holds a patent for a "Fastening member and compressor apparatus." This invention includes a bolt and a nut designed for securely attaching a compressor to a vehicle body. The fastening member features a non-circular relative rotation prevention portion located beneath the head of the bolt. A washer is non-rotatably press-fitted around this portion, allowing for a secure connection. Before attachment, the head and washer are temporarily fixed with a space in between. An elastic body, attached to the compressor, is positioned between the washer and the nut. A cylindrical member is integrated into the inner circumference of the elastic body. When the nut is screwed, the axial force is transmitted to the washer, reducing the space between the washer and the head, thus completing the attachment process. This innovative design improves the reliability and efficiency of compressor installations in vehicles.
