上記従来のものは、ねじ部が剛体であるため、非締結物を強固に締結すること ができる。しかしながら、非締結物がプラスチック等の軟質資材の場合には、締 結力が過大になって該非締結物あるいはこの非締結物に形成しためねじが損傷す る欠点があった。また、非締結物を弾性的に保持して衝撃的な負荷を緩和させた い場合には、締結部に弾性ゴムあるいはばね等を介在させねばならず、部品点数 が増大する欠点があった。また、非締結物を取り外す場合にはねじ部が非締結物 のめねじから離脱するまでボルトを緩み方向に回転させねばならず、取り外しに 時間および手数を要する欠点があった。本考案は上記欠点を解消した新規なボル トの構造を得ることを目的とする。 Since the threaded portion of the above-mentioned conventional one is rigid, non-fastened objects can be firmly fastened. However, when the non-fastened material is a soft material such as plastic, the fastening force becomes excessive and the non-fastened material or the non-fastened material is formed on the non-fastened material, so that the screw is damaged. Further, when it is desired to elastically hold the non-fastened object and reduce the shock load, it is necessary to interpose an elastic rubber, a spring, or the like at the fastening portion, which has a drawback of increasing the number of parts. Further, when removing the non-fastened object, the bolt must be rotated in the loosening direction until the threaded portion is removed from the female thread of the non-fastened object, which requires a time and labor for removal. The object of the present invention is to obtain a new bolt structure that solves the above drawbacks.
