The object intrudes into the outer surface of the pin and the sleeve from the outside. [Prior Art] The seal type chain, as shown in Fig. 1, has a seal structure ==21 and an outer plate structure. For example, there is an end of the sleeve 24 which has been dried as shown in Fig. 3, and has a variety of sealing pins 1; the type of sealing structure is embedded in the side sealing ring 3 and is sealed in two seals_ Sealing ring % and outer drawing - forming a predetermined push sealing member on the side surface of the pull-out side - ΐ =: the elasticity of the annular sealing member made of elastic material, made of eight-faced and elastic # material The ring-shaped "green"-does the side of the inner seal ring 34 and makes the outer seal ring 31 tighter than the plate 21). The inner side of the reverse 22 (refer to Japan for further improvement of the sealing property, and the double-sealed seal structure of the former, as shown in Fig. 4, is between the inner seal ring, and the outer seal ring 31 and the inner plate 2 :, the board 22, 32 (refer to Japan's special door? nnn ige〇; 丨 4 elastic sealing member 33 < JP-A-2000-136848 [Abstract] 1269003 However, in the above-mentioned full floating type sealing structure In essence, the ring seal made of jade bomb I* raw material is called “sealing, so the fine powder is easy to invade, and the sealing effect is not obtained enough. The structure, because of the function of sealing? The elastic sealing member directly contacts the 2 plate or the plate. Therefore, the elastic sealing member and the plate member slide along with the bending movement of the chain, causing the elastic sealing member to gradually wear and force. Because the outer seal ring exposes the foreign mail AL, the low τ* road material 4, the outer seal and the chain slip (for example, in the moving chain money) or the gap between the pin and the sleeve, Make the outer seal ring along The direction in which the pins are orthogonal (radial) slides; I exhibits an elastic sealing member between the outer 16% of the outer layer and the inner plate, which is worn by the friction between the side seal ring and the inner plate, and the protection effect is reduced. Reason 〇b) The problem of solving the problem is that the purpose of the invention is to provide a sealed chain that suppresses the wear of the sealing member and has a long-lasting south sealing function. To achieve the aforementioned purpose, the patent application is planned for the Chu Yue search. The sealed chain of the first item is a combination of a plurality of link assemblies; the adjacent side of the link assembly has a pair of inner plates that are orthogonal to the longitudinal direction of the chain, And a hollow cylindrical sleeve press-fitted to the inner plate; the other side of the adjacent link assembly has a side opposite to the longitudinal direction of the chain on the outer side of the pair of inner plates - an outer plate, and a pin penetrating the sleeve and being press-fitted to the outer plate; and between the inner plate and the opposite faces of the outer plate and "column: first rigid body sealing member" The inner plate and the front surface have a trapezoidal groove extending toward the outer plate; the cross section is trapezoidal The second rigid body sealing structure 1269003 is disposed in the trapezoidal groove of the second body sealing member so as to be tightly connected to the trapezoidal shape: two moon faces are in contact with the outer plate; and the sealing member made of an elastic material is disposed in the trapezoidal groove And the opposite side wall surface of the body sealing member. & The brother of the trapezoid 2, the sealed type key bar of the second paragraph of the second patent of the second patent is in addition to the composition of the fee-sealing chain of the patent r item, and the carcass The back surface of the sealing member is a concave portion of the oil storage portion; (4) The second rigid action "Ming" has the following composition and has the following unique features of the present invention. The first rigid body sealing member has a first rigid body sealing member, and the other sealing member has a trapezoidal groove with an outer plate expanded; the second rigid body has a trapezoidal groove for the first rigid body sealing member. Configured in the same with the 2? The wall is separated, the back surface is in contact with the outer plate' and the elastic material is made of: a female-shaped sealing member, which is disposed on the side wall surface of the ladder body, which is formed by the second f of the trapezoid Therefore, the sliding wear of the annular sealing member made of the elastic material and the material of the inner or outer plate is avoided. 卩/elastic sealing member The concentric movement of the first rigid body sealing member is: the contact pressure of the early area is reduced, and the 帛1 rigid body sealing structure: the dynamic wear is also reduced. Further, since the first rigid body sealing member is prevented from sliding in the direction orthogonal to the lock due to the inserting and damaging end portion, the sliding type grinding is avoided according to the second type of the sealed type of the patent application, because the second rigid 1269003 The back surface of the body seal member has a recess as an oil reservoir. Therefore, the sliding wear of the second rigid body sealing member and the outer plate is suppressed, and the fine powder is prevented from intruding between the rigid body sealing member and the outer plate to make the sealing effect last longer. [Embodiment] A preferred embodiment of the present invention will be described with reference to Figs. 1 and 2 . Fig. J is an overall sectional view showing the structure of the unsealed chain, and Fig. 2 is an enlarged cross-sectional view showing the sealing structure of the characteristic portion of the sealed chain according to the embodiment of the present invention. This part is equivalent to the part indicated by the circle A of the dotted line in the figure. The sealed chain 20 of the present invention is a chain obtained by joining a plurality of link assemblies, and one of the adjacent link assemblies has a pair of inner plates which are orthogonal to the longitudinal direction of the chain. 2b 2b and a hollow cylindrical sleeve 24 working on the pair of inner plates; the other side of the adjacent link assembly has an outer side of the pair of inner plates 2 and is orthogonal a pair of outer plates 22, 22 separated in the longitudinal direction of the chain, and pins 23 penetrating the sleeves 24 and pressing the outer plates 22, 22; the inner plate 21 and the outer plate & Between the faces: an i-th rigid body sealing member 14 having a back surface contacting the inner plate 2 and having a trapezoidal groove extending toward the outer plate 22; the second rigid body sealing member 1 being in the ith rigid sealing member The trapezoidal groove is disposed apart from the inner wall of the trapezoidal groove, the back surface contacts the outer plate 22, and the annular sealing member (〇-ring) 15 and 丨5 made of a 2-needle material. The first rigid body sealing member 14 is formed in a flat donut shape formed by trapezoidal grooves on the inner side surfaces of the push-out surfaces Ub and i4c, and the 帛2 rigid body sealing structure is used to push the surface 11b. The mountain is in the shape of a ring with a side section. Further, an annular sealing structure 1269003 made of two elastic materials is disposed; the two sealing members 15 and 15 are held by the first and second pressing faces 2c of the first U and the second rigid sealing member. hold. x, by the elastic action of the elastic-like material-like squeezing member 15 and the action of the plucking surface 〖", 1 plucking surface Ub, 14c, so that the ith rigid body (four) member ^ ― 14d elastic dust toward the inner panel 21 The outer side surface of the second rigid body sealing member is the inner side of the inner side of the crucible. Thus, even if the relative displacement occurs between the inner panel 21 and the outer panel 22 along with the _: curvature, the temple 1 rigid body sealing member 14 is tight. The state of the inner panel 21 and the state of the sealing member η tightly-sealing plate 22, and the annular sealing member of the elastic body is often subjected to the pull-out from the contact, and is often able to be stopped in the inner panel. The central force does not contact the two plates. Further, the back surface of the second rigid body sealing member is formed as an oil reservoir: the concave portion can slide the rigid body of the second rigid body sealing member u and the outer plate 22 The abrasion is reduced, and (4) the fine powder intrudes from the outside between the second door J body seal member 11 and the outer plate 22. Le's by the end of the ith rigid body sealing member 14 and the outer plate two: Elastomeric sealing member 13 having a V-shaped cross section, an annular sealing member made of material, and (4) 1 rigid body sealing member =: two-shaped Sealing member, outer plate, and second rigid body seal:; the horn 2 of the ox 2 forms the oil reservoir 17, and the wear of the second rigid body sealing member outside the spot, and the ring made of the elastic material The density, the member, and the first and second rigid body seals are further reduced.] The grinding produced by the movement 1269903. Here, the annular sealing member and the elastic sealing member made of the elastic material of the present invention are used. As long as the material has sufficient elasticity, it is not particularly limited to n, because the nitrile rubber (10) R, nitrile rubber has good oil resistance, heat resistance, and _ wearability, so it is better to turn the rubber. Also, when used in a high temperature environment' Gas rubber with good heat resistance can be suitably used
