The elastic lip 2U of the oil seal ring 21 is scraped: the excess slip oil flows down along the fine gap between the outer circumferential surface of the upper thread and the inner circumferential surface of the through hole 7 . Further, as shown in FIG. 1, an oil discharge hole 23 is formed in the inclined position on the frame i in an inclined state, and the length of the oil discharge hole 23 is from the lower end portion of the frame i to the vicinity of the front end portion of the upper wire hook guiding member 3. until. The lower end portion of the oil drain hole 23 is connected to an axle pump, a gear pump or the like (not shown) via an oil drain pipe (not shown), and is shown on the upper end portion and the oil drain hole as shown in FIG. 23 is orthogonally formed by a suction port 24 having an opening connected to the upper hook guiding body 6 and forming an upper through hole 19, and the pump and the oil drain hole 23 constitute a lubricating oil forced recovery means, and the lubricating oil is forcibly recovered. The means forcibly recovering (discharging) the excess lubricating oil absorbed and held by the porous member 25 from the suction port 24 through the oil drain hole 23 described above. Next, the operation of the squirrel car having the oil leakage preventing device of the wire hook mechanism 2 according to the first embodiment described above will be described. 17 200936837 The forward and reverse reciprocating rotation of the upper fishing line 11 in conjunction with the rotation of the sewing machine main shaft (not shown) 'the upper hook shank 13 reciprocates in the direction of the arrow u_d of FIG. 4, and by the upper hook shank 13 The reciprocating rocking motion 'the upper hook table 8 slides up and down in the direction of the arrow ill-dl of FIG. 4 in the through hole 7 of the upper hook guiding body 6, and the upper hook guiding body 6 surrounds the circular hole 5 of the upper hook guiding member 3 The center of the circle rotates back and forth. Thereby, the upper hook 10 is moved in a parabola-like manner as shown by an arrow a in FIG. 4, and cooperates with an unillustrated needle and a lower hook to form an edge lock seam. In the sewing operation, when the upper thread hook table 8 is slidably moved up and down, a part of the lubricating oil impregnated in the oil core 17 is intermittently slidingly contacted with the protruding end portion of the oil core 17 in the oil supply cylinder 16 at the lower end portion thereof. Splashing and rotating from the oil core 17 to the oil core 15 side, the lubricating oil held in the oil core i 5 gradually oozes out and adheres to the pin 14, and the adhered lubricating oil is sprayed with the reciprocal rotation of the pin 14. The mist is scattered to supply the lubricating oil to the outer peripheral surface 8a of the upper hook table 8 and to adhere to the outer peripheral surface 8a. Thereby, the lubricity of the upper and lower hook mechanisms 8 in the upper hook mechanism 2 can be satisfactorily maintained. Further, the excess portion of the lubricating oil adhering to the outer peripheral surface 8a of the upper hook table 8 is scraped by the elastic contact of the outer peripheral surface 8a of the upper hook table 8 with the elastic seal lip 21a of the oil seal ring, thereby It is possible to prevent the excessive lubricating oil from flying up the hook 6 and the upper fishing guide member 3 (scattering oil) and causing a situation such as a foul line or a cloth. Further, a portion of the excess lubricating oil scraped off by the outer peripheral surface 8a of the upper hooking table 8 by elastic contact with the elastic lip of the oil seal cymbal 21, the outer peripheral surface and the through hole of the upper fishing table 8 are shun 18 200936837 The fine gap between the circumferential surfaces of the inner surface of 7 is slid down, and is immediately absorbed and held by the oil absorbing ring 22 disposed at the lower portion of the oil seal ring 21, thereby preventing excess lubricating oil from following the circumferential surface of the upper hook table 8. 8a or the inner peripheral surface of the through hole 7 flows downward to smudge the state of the rack 1 and the like, and the lubricating oil absorbed and held by the oil absorbing ring 22 is again supplied from the inner peripheral surface of the oil absorbing ring 22 to the upper hook table 8 The outer peripheral surface I is recycled to the lifting movement of the upper hook table 8, so that no lubricating oil is wasted, the overall amount of lubricating oil can be reduced, and the lifting movement of the upper hook table 8 can be maintained for a long period of time. . On the other hand, by the elastic contact with the elastic lip 21a of the oil seal ring 21, the remaining portion of the excess lubricating oil scraped off by the outer peripheral surface 8& of the upper hook table 8 is wound back to the outer periphery of the oil seal ring 21. And being absorbed and held by the porous member ,, (10), if the assisting machine is running at a high speed, even if the oil supply amount to the upper fishing platform 8 is increased, the excess lubricating oil scraped by the elastic lip 2u of the oil seal ring 21 is followed. As a result of the increase in the amount, the amount of absorbed oil in the porous member 25 is increased to reach a saturated state, and the lubricating oil absorbed by the porous member 25 can be forcibly recovered and discharged by the forced oil recovery means. By 2', it is possible to prevent the excess of the scraped _ method from being slid to the upper side of the oil seal ring 21 with the reciprocating rotation of the upper line fishing rod, and then attached to the outer peripheral surface 8a of the upper thread hook table 8 and then scattered upward. The oil leakage prevention function is reduced in the inside, so that the expected oil leakage prevention function can be stably maintained for a long period of time. Further, the elastic lip formed on the oil seal ring 21 by the body is: = the upper portion of the upper fishing guide member 3 Dust such as swarf which is scattered and scattered, "in the through hole 7", it is also possible to prevent the above-mentioned dust from invading the upper fishing surface 8 19 200936837 between the outer peripheral surface 8a and the inner peripheral surface of the through hole 7, or to be scraped The problem of excess oil in the shellfish and other problems. & Reduced Lubrication Performance As described above, the lubricating property is maintained by continuously supplying the lubricating oil, and the lubricating oil is scattered upward to cause the wire or the cloth to be received. The prevention of the actual oil leakage prevention function continues, the circulation of excess lubricant = the function, and the prevention of dust immersing in the through hole 7 and the function of using the fire dust to break into the excess lubrication oil. Smooth and copy the action of the car. Fig. 11 to Fig. 16 are enlarged views showing a part of the oil leakage prevention μ of the line fishing mechanism according to the second embodiment of the present invention. In the second embodiment, the upper and lower through holes 19 and 20 are formed to be orthogonal to the through hole 7 in the radial direction of the upper line fishing guide 6, and are guided by the upper hook as shown in FIG. A total of four oil grooves 26 are formed at a position substantially symmetrical with respect to the two sides of the body 6 in the direction of the axis of rotation 6a, 6b and on the sliding axis of the upper hook table 8, and are formed in the frame in an inclined state. The suction port 24 connected to the upper end of the oil drain hole 23 of a pump (not shown) such as an axle pump or a gear pump via a drain pipe (not shown) is connected to the upper wire as shown in FIG. The hook guide body is formed with a lower portion penetrating through the long hole 2, and the oil drain hole 23 to which the suction port 24 is attached, the pump and the oil groove 26 constitute a lubricating oil forced recovery means. The other components are the same as those in the first embodiment, and therefore, the same reference numerals will be given to the corresponding members and the parts, and the detailed description will be omitted. The oil leakage preventing device 20 including the above-described second embodiment of the wire hook mechanism 2 is basically the same as that of the first embodiment, but by the 4+ phase R ' ^ The elastic lip 21a of the sealing ring 21 is elastically contacted from the upper hook opening, and the excess lubricating oil scraped off by the outer peripheral surface 8a is different from the first embodiment t. Therefore, the following processing of the excess lubricating oil will be described below. . That is, by the elastic contact with the elastic lip 21a of the oil seal ring 21, the excess circumferential oil is scraped from the outer peripheral surface of the upper hook table 8 and is wound back to the outer periphery of the oil seal ring.

(4) The oil flows down through the Δ-groove 26 to the lower through-hole 2 〇 side and along the outer peripheral surface 8a of the upper hook 8 or the inner circumference of the through-hole 7 The lubricating oil which flows down and flows downward is absorbed and held by the oil absorbing ring 22, and the lubricating oil absorbed and held by the oil absorbing ring 22 is forcibly recovered by the above-mentioned lubricating oil forced recovery means and discharged. Therefore, even in the case of the second embodiment, especially when the oil supply amount to the outer peripheral surface 8a of the upper hook D8 is increased, the excess lubricating oil scraped off can be prevented from being partially accompanied by the upper hook guiding body 3. When the reciprocating rotation is applied to the upper side of the oil seal ring 21 and is again attached to the outer peripheral surface of the upper thread hooking table 8, the oil leakage preventing function is reduced in the short-term direction, so that the expected oil leakage preventing function can be stably maintained for a long period of time. Further, in the first and second embodiments, the dust seal elastic lip 21b and the excessive lubricating oil scraping elastic lip 2U are integrally formed on the oil seal ring 21, but the oil seal ring 21 may be used. A dust seal ring with an elastic lip for dustproof sealing is separately provided, and the dust seal ring is fitted into the through hole 7 of the upper hook hook conductor 6 at a position higher than the oil seal ring 21. In this case, it is possible to surely prevent the self-winding from being able to guide #6 and the upper line 21 200936837. The dust scattered in the upper portion of the guide member 3 invades into the oil seal ring 21 of the scraping elastic lip 21a having excess lubricating oil. The position is embedded, and the effect of preventing the occurrence of the above problem can be further improved, that is, dust invades between the outer peripheral surface 8a of the upper hook table 8 and the inner peripheral surface of the through hole 7 to be worn. The reason, or mixing into the excess oil scraped off, is the cause of the deterioration of the lubricating performance. Further, in the first embodiment, the suction port 24 that connects the oil drain hole 23 of the pump to the upper end of the upper hook guide body 6 is connected to the upper hook guide body 6 to form an upper through hole 19'. As shown by the broken line in FIG. 1A, the suction port 24 which is also open to the lower through hole 20 is also provided. Further, as shown in the above-described embodiment, the oil drain hole 23 of the frame 1 is formed by piercing in a straight line state from the lower end portion of the frame 1 to the vicinity of the end portion of the upper hook guiding member 3. However, the present invention is not limited thereto, and may be formed by combining a hole having a slight inclination slope and formed in a horizontal state with a hole formed by being connected to the hole and formed in a vertical state.
