A shown in FIGS. 1 and 4 is a screw support device that supports the male screw S when the male screw S is tightened to the fastened member T having the female screw Ta. The screw support device A includes a body member 1 having a passing region 1a that communicates from the receiving side X that receives the male screw S to the fastened member side Y and allows the male screw S to pass through, and the male screw S that passes through the passing region 1a. It is provided with a plurality of support units 2 for abutting and supporting the male screw S. In the first embodiment, two support units 2 are provided for one passage region 1a. As shown in FIG. 1, the upper part is the head of the male screw S, and the lower part is the threaded portion of the male screw S, which is supplied to the body member 1.

ボディー部材１には、通過領域１ａの周囲に等間隔に配置され、且つ複数の支持ユニット２（図２（ｂ）、図４及び図５参照）に１対１で対応し、且つ受入側Ｘおよび被締結部材側Ｙのいずれかに開放された複数の収納凹部１Ａが形成されている。実施例１において、１つの通過領域１ａに対して２つの収納凹部１Ａが設けられている。また、実施例１において、複数の収納凹部１Ａは、受入側Ｘに開放されている。 The body member 1 is arranged at equal intervals around the passage region 1a, has a one-to-one correspondence with a plurality of support units 2 (see FIGS. 2B, 4 and 5), and has a receiving side X. A plurality of storage recesses 1A opened to any of the fastened member side Y are formed. In the first embodiment, two storage recesses 1A are provided for one passage region 1a. Further, in the first embodiment, the plurality of storage recesses 1A are open to the receiving side X.

各支持ユニット２は、雄ねじＳに当接可能な第１当接部２０ａ及び収納凹部１Ａにおける通過領域側の側壁に当接可能な第２当接部２０ｂを有する当接部材２０と、当接部材２０を収納凹部１Ａにおける通路領域１ａ側の側壁に向けて付勢する付勢手段２１とを含んでいる。第１当接部２０ａは、雄ねじＳの頭部又は雄ねじＳのネジ部に当接する。
実施例１において、当接部材２０は、円柱体であり、第１当接部２０ａは、円柱体の円周側面の中央部位であり、第２当接部２０ｂは、円柱体の円周側面の中央部位より円柱体の円周側面の端部に近い側である。当該構成によれば、雄ねじＳを支持する部位は円柱体の円周側面の中央部位であるため、雄ねじＳを締め付ける際、雄ねじＳは、抵抗が少なく通過領域１ａをスムースに通過することができる。 Each support unit 2 is in contact with a contact member 20 having a first contact portion 20a capable of contacting the male screw S and a second contact portion 20b capable of contacting the side wall on the passage region side in the storage recess 1A. It includes an urging means 21 for urging the member 20 toward the side wall on the passage region 1a side in the storage recess 1A.

In the first embodiment, the contact member 20 is a cylinder, the first contact portion 20a is a central portion of the circumferential side surface of the cylinder, and the second contact portion 20b is the circumferential side surface of the cylinder. It is the side closer to the end of the circumferential side surface of the cylinder than the central part of. According to this configuration, since the portion that supports the male screw S is the central portion of the circumferential side surface of the cylindrical body, when the male screw S is tightened, the male screw S has little resistance and can smoothly pass through the passage region 1a. ..

そして、複数の収納凹部１Ａに設置された複数の支持ユニット２における複数の第１当接部２０ａは、付勢手段２１の付勢力によって雄ねじＳと当接可能な通過領域１ａに出現し、雄ねじＳを保持する。実施例１において、付勢手段２１は、スプリングである。 Then, the plurality of first contact portions 20a in the plurality of support units 2 installed in the plurality of storage recesses 1A appear in the passage region 1a capable of contacting the male screw S by the urging force of the urging means 21, and the male screw Hold S. In the first embodiment, the urging means 21 is a spring.

このように複数の支持ユニット２で雄ねじＳを支持でき、しかも、複数の支持ユニット２が収納される複数の収納凹部１Ａが受入側Ｘおよび被締結部材側Ｙのいずれかに開放されているため、支持ユニット２の取り付け、取り外しを容易に行うことができる。 In this way, the male screw S can be supported by the plurality of support units 2, and the plurality of storage recesses 1A in which the plurality of support units 2 are housed are open to either the receiving side X or the fastened member side Y. , The support unit 2 can be easily attached and detached.

また、雄ねじＳが通過領域１ａにないときに、第２当接部２０ｂは、付勢手段２１の付勢力によって収容凹部１Ａにおける通路領域１ａ側の側壁に当接する。この構成によれば、第１当接部２０ａ同士が当接する場合に比べ、抵抗が少なく、複数の支持ユニット２による雄ねじＳの支持をスムースに行うことができる。 Further, when the male screw S is not in the passage region 1a, the second contact portion 20b abuts on the side wall on the passage region 1a side in the accommodating recess 1A by the urging force of the urging means 21. According to this configuration, the resistance is small as compared with the case where the first contact portions 20a are in contact with each other, and the male screw S can be smoothly supported by the plurality of support units 2.

更に、詳述すれば、図４に示すように、雄ねじＳのネジ部が、２つの付勢手段２１によりそれぞれ付勢された２つの当接部材２０の隙間（通過領域１ａ）に位置し、２つの当接部材２０に雄ねじＳの頭部裏面が支持され［図４（ａ）］、支持された雄ねじＳをドライバーＤで雄ねじＳの下方に位置する雌ネジＴａを有する被締結部材Ｔに締め付ける際に使用されるものである［図４（ｂ）（ｃ）］。 Further, more specifically, as shown in FIG. 4, the threaded portion of the male screw S is located in the gap (passing region 1a) of the two contact members 20 urged by the two urging means 21, respectively.
