When the rolling element support 4 rotates, the position of the rolling element 6 provided on the rolling element support 4 facing the concave arc portion 3 1 of the inner wall surface 3 of the hole 2 1 of the main body 2 changes. For example, in the concave arc portion 3 1 of the inner wall 3, the one that was in contact with the inclined surface 3 21 of the convex arc portion 3 2 on the right side of the valley bottom surface 3 11 of the concave arc portion 3 1 is the reverse of the rolling element support member 4. By the movement in the direction, the rolling element 6 moves so as to come into contact with the inclined surface 3 21 of the convex arc portion 3 2 on the left side of the valley bottom surface 3 11 opposite to the front, and connects the drive shaft body 5 and the main body 2 to each other. The rotation of the main barrel 2 causes the drive shaft body 5 to rotate in the opposite direction to the previous direction, and when the previous operation is tightening the screw, this reverse rotation loosens the tightened screw. A contact rolling element 6 to the concave arc portion 3 1 of the trough bottom 3 11 when the opposed and rolling elements 6 are concave arc portion 3 has a 1 away are in interval 7 from the drive shaft 5 is connected with Manual 2 Even if the main body 2 is rotated and the main body 2 is rotated, the drive shaft 5 does not rotate, and only the main body 2 idles. The pushing claw 9 is urged by the elastic force of the spring 8 so that the toe 9 1 strongly contacts the outer peripheral wall surface of the rolling element support 4, so that the rolling support 4 is pushed by the pushing claw 9. Rotation is regulated and delusion can be regulated.

この考案はラチエットの構成が簡単であるため製造が容易で安価に形成するこ とができ安価なラチエットハンドルを提供することができ、また使っても歯車と 送り爪による駆動方式ではないため駆動ハンドルを操作しても騒音の発生のない 静かなものであるとともに転動子支受体４の回動も転動子６が主胴２の波形周面 の凸弧部32の傾斜面３21から離れて凹弧部31側に移動すると主胴２からの規制が 解除され軽快に空転し、長時間の作業においても駆動軸体５を駆動するときのみ しか手は力を入れて働かないため作業者の手の疲労が少ないものである。さらに ネジ等の緊締や緊締を緩める際に強力な緊つけや逆に緊付けのかたいネジを緩め るとき駆動ハンドル１に強力な力を加え主胴２を回動させても転動子６と駆動軸 体４との係合が破壊されることがなく故障発生の少ないもので駆動軸体５はボッ クス12を介してネジに強力に作用しネジの緊締や緊締を緩めることが出来る。胴 部２の孔21の波形周面を構成する凹弧部31と凸弧部32の条数を多くしておくと駆 動ハンドル１の回転のストロークが短かくなり狭隘な場所での使用において駆動 ハンドル１を駆動軸体５に対し最適の位置に定位させることができるハンドル操 作の容易なものである。駆動軸体５に加えられる主胴２からトルクは転動子支受 体４に支受された複数の転動子６が駆動軸体５の全周からトルクを加えものであ るから駆動軸体５にトルクを均等に伝えることができて駆動軸体５は主胴２内で 孔21の内壁３に片寄ることがなく主胴２に支受され駆動軸体５の中心が主胴２の 中心から孔21の偏移することがなく正確な回動をすることができるものであり、 転動子６の数を複数にすると主胴２から転動子６が受ける力が分散され例えば転 動子６が６個あると各個が受ける力は６分の１になり駆動軸体５に強力なトルク を加えても各転動子６はそれぞれ６分の１づつの負担でよく力の負担が軽いから 損傷が少なく、主胴２からの強力なトルクを受けてもスリップが生じることなく これを駆動軸体５へ有効に伝えることができる効果を奏する。This invention can provide an inexpensive ratchet handle which is easy to manufacture and inexpensive because the structure of the ratchet is simple, and even if it is used, it is not a drive system using gears and feed pawls No noise is generated even when is operated, and the rolling element supporter 4 is rotated so that the rolling element 6 is inclined surface 3 21 of the convex arc portion 3 2 of the corrugated peripheral surface of the main body 2. only the hand does not work emphasizes only when regulations from Manual 2 when moving to the concave arc portion 3 1 side is canceled lightly idling, also driving the drive shaft 5 in prolonged activity away from Therefore, the operator's hand fatigue is small. Furthermore, when tightening or loosening screws, etc., or when loosening the hard screws that are tightened, conversely, even if a strong force is applied to the drive handle 1 and the main body 2 is rotated, The engagement with the drive shaft body 4 is not broken, and the occurrence of failure is small, and the drive shaft body 5 strongly acts on the screw via the box 12 and can tighten or loosen the screw. If the number of concave arcs 3 1 and convex arcs 3 2 that form the corrugated peripheral surface of the hole 2 1 of the body 2 is increased, the rotation stroke of the drive handle 1 becomes shorter and in a narrow place. The use of the drive handle 1 makes it possible to orient the drive handle 1 at an optimum position with respect to the drive shaft body 5, which facilitates the handle operation. The torque applied from the main body 2 to the drive shaft 5 is due to the fact that the plurality of rolling elements 6 supported by the rolling element support 4 apply the torque from the entire circumference of the drive shaft 5. to be able to transmit torque evenly to the body 5 drive shaft 5 centered Manual 2 holes 2 1 be biased to the inner wall 3 of the支受in Manual 2 without drive shaft 5 in the Manual 2 are those that can be shifted from the center of the hole 2 1 a correct rotation, without the number of rolling elements 6 is subjected when a plurality of Manual 2 forces rolling members 6 are dispersed For example, if there are six rolling elements 6, the force received by each element will be 1/6, and even if a strong torque is applied to the drive shaft 5, each rolling element 6 will be able to bear a 1/6 load. Since the load on the drive shaft is light, there is little damage, and slipping does not occur even when a strong torque is applied from the main body 2, and this is effectively transmitted to the drive shaft body 5. Achieves the effect can be.
