（産業上の利用分野）
本考案は、特に精密機械、精密部品等の組み立
て分解に適したドライバーに関する。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a screwdriver particularly suitable for assembling and disassembling precision machines, precision parts, etc.
（従来の技術）
手を持ち替えることなく回動操作できるドライ
バーが、実開昭57−131269号に開示されている。
これは、第８図に示すようにドライバーの把手部
１０に被着されるアタツチメント１１であるが、
その頂端に上方に凹のサラワツシヤ１２が、平頭
ボルト１３によつて回動自在に止着されており、
平頭ボルト１３は、ワツシヤ１４、サラワツシヤ
１５、ナツト１６，１７によつてアタツチメント
１１に取り付けられたものである。(Prior Art) A screwdriver that can be rotated without changing hands is disclosed in Utility Model Application No. 57-131269.
This is an attachment 11 attached to the handle part 10 of a screwdriver as shown in FIG.
An upwardly concave sillage 12 is rotatably fixed to its top end by a flat head bolt 13.
The flat head bolt 13 is attached to the attachment 11 by a washer 14, a flat washer 15, and nuts 16 and 17.
従つて、手のひらでサラワツシヤ１２を押圧し
つつ指先でドライバーの把手部１０を回動できる
ので、ドライバーを手で持ち替えることなく捻子
を螺回できるというものである。 Therefore, since the user can rotate the handle part 10 of the screwdriver with his/her fingertips while pressing the screwdriver 12 with the palm of the hand, the screwdriver can be turned without changing the driver's hand.
（考案が解決しようとする課題）
ところが、上記従来例は、サラワツシヤ１２を
アタツチメツト１１に対して回動自在とするため
に、サラワツシヤ１２と平頭ボルト１３の間には
所謂あそびが必要であり、また構造が複雑で部品
点数が多いことにも起因してガタつきの発生とい
う問題があつた。(Problems to be Solved by the Invention) However, in the conventional example described above, in order to make the flat head bolt 12 rotatable with respect to the attachment 11, a so-called play is required between the flat head bolt 13 and the flat head bolt 13. Due to the complex structure and large number of parts, there was a problem of looseness.
その上、サラワツシヤ１２は、手のひらに対し
て密着させておく必要から、捻子の軸心方向に強
い荷重を加えることになり、上記問題を含めて精
度が要求される精密部品用のドライバーに不都合
であつた。 Furthermore, since the Sarawatsha 12 needs to be kept in close contact with the palm of the hand, a strong load is applied in the axial direction of the screw, which is inconvenient for drivers for precision parts that require precision, including the above-mentioned problem. It was hot.
そこで、本考案は、構造が簡単で部品点数が少
なく、安定して捻子と軸杆を同一軸線状に保持し
て、回動操作の際に手を持ち替える必要のない、
精密部品等の組み立て分解に適したドライバーを
提供することを目的とする。 Therefore, the present invention has a simple structure, has a small number of parts, stably holds the screw and shaft on the same axis, and eliminates the need to change hands when rotating.
The purpose is to provide a screwdriver suitable for assembling and disassembling precision parts.

A center holding protrusion 8 having the same axis as the shaft rod 1 and an outer ring part 9 for rotational guidance concentrically surrounding the protrusion 8 are integrated into the tail end portion 7 of the handle 4 fixed to the handle 4. The outer ring portion 9 is protruded in a chevron-shaped cross section so that the width gradually becomes narrower on the tip side, and the diameter of the outer ring portion 9 is as follows:
The protrusion 8 has a size that fits within the abdomen of the fingertip of the index finger A, and the protrusion 8 has an outer ring so that the outer ring part 9 rotates around the protrusion 8 with respect to the abdomen of the fingertip of the index finger A that reaches the tail end portion 7. The tips of the protrusion 8 and the outer ring part 9 are rounded 8a and 9 so that the protrusion 8 and the outer ring part 9 slide smoothly against the abdomen of the fingertip of the index finger A.
A is provided in the middle of the handle 4, and a rotation operation part 5 provided with a knurled anti-slip 6 is provided in the middle of the handle 4 for rotation operation by gripping between the thumb B and middle finger C. We adopted a structure in which there are

フイツトする。(Function) As shown in FIG. 6, when the screwdriver according to the present invention engages the bit part 2 with the head of the screw a and lightly places the index finger A on the tail end part 7, As shown, the protrusion 8 and the outer ring part 9 provided on the tail end portion 7 form depressions A' and A'' due to the elasticity of the flesh corresponding to the pad of the index finger A, respectively, and the depressions A' and A'' are formed by the elasticity of the flesh.
A'', and the index finger A fits on the tail end portion 7.
そして、外輪部９よりも突起８の方が突出して
いるので突起８が好適なセンターとなり、外輪部
９が回動の際人指し指Ａに添つて案内としてブレ
を防止し、人指し指Ａに対して摺接回動自在に保
持される。 Since the protrusion 8 protrudes more than the outer ring part 9, the protrusion 8 becomes a suitable center, and the outer ring part 9 acts as a guide along the index finger A during rotation to prevent shaking and slide against the index finger A. It is held rotatably.
従つて、このドライバーは、親指Ｂと中指Ｃに
よる回動操作にも拘らず常時安定して捻子ａと軸
杆１を同一軸線状に保持した状態、すなわち手を
持ち替えることなく回動操作できる。 Therefore, this screwdriver can be rotated in a state in which the screw a and the shaft rod 1 are always held stably on the same axis even though the screwdriver is rotated by the thumb B and the middle finger C, that is, the screwdriver can be rotated without changing hands.

ライバーとすることができる。(Effects of the invention) According to the invention, the protrusion 8 for center holding and the outer ring part 9 for rotational guidance are protruded from the tail end part 7 of the handle 4, and the outer ring part 9 gradually becomes narrower on the tip side. The diameter of the outer ring portion 9 is sized to fit within the abdomen of the tip of the index finger A, so that by simply placing the index finger A lightly on the tail end portion 7, the protrusion 8 and In the outer ring part 9, hollows are formed in the abdomens of the tips of the index fingers due to the elasticity of the flesh, so that the fingers can be easily supported therein. Further, so that the outer ring portion 9 rotates around the protrusion 8 with respect to the abdomen of the fingertip of the index finger A directed toward the tail end portion 7,
The protrusion 8 is formed with a slightly larger protrusion than the outer ring part 9, and the tips of the protrusion 8 and the outer ring part 9 are rounded 8a, so that the protrusion 8 and the outer ring part 9 slide smoothly against the abdomen of the fingertip of the index finger A. 9a, the protrusion 8 becomes a suitable center when rotating the screwdriver, and the outer ring part 9 smoothly guides the rotation to prevent the driver from wobbling. By working together, the screwdriver can be slidably rotated against the abdomen of the tip of the index finger A. Moreover, the thumb B and middle finger C are placed in the middle of the handle 4.
Since a rotation operation part 5 with a knurled anti-slip 6 is provided for rotation operation by pinching between the screwdriver and the screwdriver, the screwdriver can be slidably rotated with the index finger A as described above. At the same time, it becomes possible to rotate the screwdriver easily and smoothly using the thumb B and middle finger C. Therefore, we have created a precision component that has fewer parts and a simpler structure than conventional ones, but that can always stably hold the shaft rod 1 of the screwdriver on the same axis as the screw, and that can be easily rotated without changing the grip by hand. It can be used as a screwdriver suitable for assembling and disassembling.
