[Problems to be Solved by the Invention] Furthermore, in the slide fastener described in Patent Document 1, the upper stopper is used as a stopper for the back portion which is not easily detached from the fastener chain cloth, the bulging portion, the protruding portion, and the like. Since the structure which functions as a part has a structure of a different part, it has a tendency for an upper stop to become large. An object of the present invention is to provide a zipper which is not easily detached from the zipper chain cloth and is capable of functioning as a stopper and has a stopper smaller than the conventional one. [Technical Means for Solving the Problem] The zipper of the present invention is characterized in that it is a zipper including a pair of zipper fastener tapes having a zipper chain cloth and a zipper fastener element row along the side edge portion of the zipper chain cloth, and An upper stopper is arranged at one end of each of the fastener element rows, and the upper stopper has an upper stopper front portion and an upper stopper front portion. The upper stopper back portion is continuously attached to the front surface of the zipper chain, the upper stopper back portion is attached to the back surface of the zipper chain, and the upper stopper back portion is slid on the slider. It can be arranged opposite to the sliding member in the direction in contact with the sliding member. According to the slide fastener of the present invention, since the upper stopper has the upper stopper front portion and the upper stopper back portion attached to the front and back surfaces of the fastener chain, for example, it can be compared with the upper stopper without the upper stopper back portion. The upper stop is configured to be difficult to fall off from the zipper chain. In addition, when the slider slides and is arranged at one end portion of the zipper element row, the upper surface of the stopper is arranged to face the slider in the sliding direction to abut the slider, so that the slider can be restricted. slide. In this way, the structure of the upper stopper back surface portion makes it difficult to fall off from the zipper chain cloth and can function as a stopper portion. Therefore, there is no need to separate the structure that is not easily removed from the zipper chain cloth and serve as a stopper portion. The functioning structure is composed of different parts, and the upper stop can be made smaller. In the slide fastener of the present invention, it is preferable that the upper stop front portion has a holding portion in which a fastener element constituting one end portion of the fastener element row is embedded, and the upper stop is in a thickness direction from the upper stop. The facing portion is opposite to the facing portion, and the holding portion and the facing portion are disposed at different positions in the sliding direction. According to this configuration, the upper stop back surface portion is arranged to face the rear side of the facing portion that is disposed at a position different from the holding portion in the sliding direction. Therefore, the upper stop back surface portion can be reinforced to embed the chain. The holding portion of the teeth is more likely to face off the facing portion from the fastener chain, and it is possible to suppress the facing portion from coming off from the fastener chain. In the slide fastener of this invention, it is preferable that the said opposing part is arrange | positioned ahead of the said holding | maintenance part in the said sliding direction.

Position along the inside surface of the upper stop front portion. According to this configuration, the front end of the upper stop back surface portion is arranged along the inner side surface of the upper stop front surface portion in the thickness direction of the upper stop surface. Therefore, the upper stop front surface portion and the upper stop rear surface are not formed. One of the parts protrudes from the other in the width direction of the fastener chain. Since such a protruding portion is not formed, there is no case where a portion of the zipper chain cloth attached to the protruding portion is not supported by the other of the upper stop front portion and the upper stop back portion and falls off. In the slide fastener of this invention, it is preferable that the width | variety of the said upper stopper back surface part becomes wide as it goes from the base end side toward the said front end side. According to this configuration, the front end side of the upper stop back surface portion is separated from the continuous base end side of the upper stop front surface portion. Therefore, it is more difficult to drop off the fastener chain cloth than the base end side of the upper stop back portion. It is lowered, but by increasing the width of the front end side of the upper stop back surface portion to increase the area of attachment to the zipper chain cloth, it is possible to make the front end portion of the upper stop back surface portion difficult to fall off from the zipper chain cloth. In the slide fastener of this invention, it is preferable that the said upper stopper back surface part is a shape located in the said sliding direction behind from the base end side toward the said front end side. According to this configuration, when the slider is moved in the sliding direction in which the zipper is closed, and abuts against the back portion of the upper stop, the front side of each sliding direction of the upper stop is directed toward the width direction inner side of the zipper chain, In addition, the rotating force of the sliding direction rear side toward the outer side in the width direction of the zipper chain cloth sandwiches the guide post portions 413 of the slider with each other from the rear side in the sliding direction of the upper stop, so that the rattling of the slider can be suppressed. In the slide fastener of the present invention, it is preferable that the slider has a lower plate portion disposed on the back side of each of the fastener element rows, and the upper stop back portion has an abutment on the lower direction in the sliding direction. The upper surface of the plate portion faces a stopper surface opposite to the upper surface of the plate portion, and the stopper surface has a shape along the upper surface of the lower plate portion. According to this configuration, the stopper surface has a shape along the upper surface of the lower plate portion of the slider. Therefore, the entire surface of the stopper surface can be brought into contact with the upper surface of the lower plate portion. Therefore, the impact when the slider hits the stopper can be spread over the entire surface of the stopper surface, and concerns such as breakage of the stopper surface can be reduced. In the slide fastener of the present invention, it is preferable that the slider has an upper plate portion disposed on the front side of each of the fastener element rows, a lower plate portion disposed on the back side of each of the fastener element rows, and connecting the above. The upper plate portion and the guide pillar portion of the lower plate portion are set to a size A from the front outer surface of the upper stop front portion to the back of the zipper chain cloth, and the front of the upper stop front portion is outside. The dimension from the surface to the outer surface of the back surface of the upper stopper is the dimension B. When the dimension from the inner surface of the upper plate to the inner surface of the lower plate is C, the dimension relationship is A < C <B. According to this configuration, when the slider is disposed at one end portion of the fastener element row, the upper stop front portion can be inserted between the upper plate portion and the lower plate portion of the slider, and the upper stop back portion can be inserted. The slider abuts against the lower plate portion of the slider to stop the slider. In the slide fastener of this invention, it is preferable that the outer side surface of the said upper stopper front part has a bulging part which bulges to the outer side of the said fastener chain width direction. According to this configuration, in the closed state of the zipper, the gap between the bulged portion of the upper stopper and the guide post portion can be narrowed, and the bulged portion can be brought into contact with the guide post portion, thereby suppressing the slider from Shake in the width direction of the zipper chain. Furthermore, since the continuous portion of the upper stop front surface portion and the upper stop back surface portion also includes a bulging portion, the continuous portion can be made larger, and the strength of the upper stop can be improved. [Effects of the Invention] According to the present invention, it is possible to provide a zipper which is not easily detached from the fastener chain cloth and can function as a stopper and has a stopper smaller than the conventional one.

Therefore, the upper-stop back surfaces 271 and 371 and the opposing sides 269 and 369 of the opposing portions 269 and 369 that are arranged at positions different from the holding portions 268 and 368 in the sliding direction are opposite to each other. The sections 271 and 371 reinforce the opposing sections 269 and 369 which are easier to fall off from the fastener chain cloths 21 and 31 than the retaining sections 268 and 368 embedded with the linear fastener elements 25 and 35, and can restrain the opposing sections 269 and 369 from the zipper chain. The cloths 21 and 31 fall off. (3) The opposing portions 269 and 369 are arranged further forward than the holding portions 268 and 368 in the sliding direction of the slider 4. Therefore, in a state where the slider 4 is in contact with the upper stop back portions 271 and 371, the upper stop front portions 261 and 361 can be positioned more in the sliding direction of the slider 4 than the facing portions 269 and 369. The rear part is contained in the slider 4. (4) Portions of the back surfaces 21B and 31B facing the portions of the front surfaces 21A and 31A of the fastener chain fabrics 21 and 31 to which the holding portions 268 and 368 are attached are exposed. Therefore, the upper stopper back portions 271 and 371 can be eliminated from the back side of the holding portions 268 and 368 which are the portions where the linear fastener elements 25 and 35 are embedded and are not easy to fall off from the fastener chain fabrics 21 and 31, and the upper stopper 26 can be achieved. , 36 miniaturization.

The front ends 275 and 375 of the back portions 271 and 371 are arranged at positions along the thickness direction of the upper stops 26 and 36 along the inner side surfaces 265 and 365 of the upper stops front portions 261 and 361. Therefore, the front ends 275 and 375 of the upper stop back portions 271 and 371 are arranged along the inner sides 265 and 365 of the upper stop front portions 261 and 361 in the thickness direction of the upper stops 26 and 36. One of the upper stopper front portions 261 and 361 and the upper stopper back portions 271 and 371 is not formed in the width direction of the fastener chain cloths 21 and 31 with respect to the other. Since such a protruding portion is not formed, the portion of the fastener chain cloth 21, 31 where there is no such protruding portion is not supported by the other of the upper stop front portions 261, 361 and the upper stop back portions 271, 371. And the case of shedding. (6) The widths of the upper stopper back surface portions 271 and 371 become wider as they go from the base ends 272 and 372 toward the front ends 275 and 375. Therefore, the front ends 275 and 375 of the upper stop back portions 271 and 371 are far away from the base ends 272 and 372 sides which are continuous with the upper stop front portions 261 and 361. Compared with the 372 and 372 sides, the difficulty of falling off from the zipper chain cloths 21 and 31 is reduced, but by increasing the width of the front ends 271 and 371 at the front ends 275 and 375, the zipper chain cloths 21 and 31 are enlarged. The adhered area can prevent the parts on the front ends 275 and 375 of the upper stopper back portions 271 and 371 from falling off from the fastener chain cloths 21 and 31 easily. (7) The upper stop back portions 271 and 371 are located rearward in the sliding direction from the base ends 272 and 372 toward the front ends 275 and 375. As shown in FIG. 7, if the rear direction of the sliding direction is downward, It has a downwardly inclined shape. Therefore, when the slider 4 is moved in the sliding direction in which the slide fastener 1 is closed and abuts the above-mentioned upper stopper back portions 271 and 371, the upper stoppers 26 and 36 generate their sliding direction forward side toward the fastener chain cloth. The rotation force of the inner side of 21 and 31 in the width direction and the rear side of the sliding direction toward the outer side in the width direction of the zipper chain cloth 21 and 31 sandwich the guide post portion 413 of the slider 4 by the upper stopper 26 and the lower part of each other. Therefore, it is possible to suppress rattling of the slider 4.

The surface 412C is opposed to the stopper surfaces 276 and 376, and the stopper surfaces 276 and 376 have a shape along the upper surface 412C of the lower plate portion 412. Therefore, the stopper surfaces 276 and 376 are shaped along the upper surface 412C of the lower plate portion 412 of the slider 4, and therefore, the entire surfaces of the stopper surfaces 276 and 376 can abut on the lower plate portion 412. Surface 412C. Therefore, the impact when the slider 4 hits the upper stops 26 and 36 can be spread over the entire surfaces of the stopper surfaces 276 and 376, and damage to the upper stops 26 and 36 can be prevented. (9) The slider 4 has an upper plate portion 411 disposed on the front side of each of the fastener element rows 24 and 34, a lower plate portion 412 disposed on the back side of each of the fastener element rows 24 and 34, and an upper plate portion 411 is a guide pillar portion 413 connected to the lower plate portion 412, and the size of the front outer surfaces 262 and 362 of the upper stop front portions 261 and 361 to the back surfaces 21B and 31B of the zipper chain cloths 21 and 31 is set to size A, Set the dimensions of the front outer surfaces 262, 362 of the upper stop front portions 261, 361 to the outer outer surfaces 277, 377 of the upper stop back portions 271, 371 to size B, and the inner surface 411B of the upper plate portion 411 to the lower plate. When the size of the inner surface 412B of the portion 412 is set to the size C, the dimensional relationship is A <C <B. Therefore, when the slider 4 is disposed on the upper end portions 24A and 34A of the fastener element rows 24 and 34, the upper stop front portions 261 and 361 can be inserted into the upper plate portion 411 and the lower plate portion 412 of the slider 4. In addition, the upper stopper back surface portions 271 and 371 can be brought into contact with the lower plate portion 412 of the slider 4 to stop the slider 4. (10) The outer side surfaces 264 and 364 of the upper stopper front portions 261 and 361 have bulged portions 264A and 364A that bulge outward in the width direction of the fastener chain cloths 21 and 31. Therefore, in the closed state of the zipper 1, the gap between the bulged portions 264A and 364A of the upper stops 26 and 36 and the guide pillar portion 413 can be narrowed, and the bulged portions 264A and 364A can be brought into contact with the guide pillar portion 413. Therefore, it is possible to prevent the slider 4 from rattling in the width direction of the fastener chain cloths 21 and 31. Further, the continuous portions 273 and 373 of the upper stop front portions 261 and 361 and the upper stop back portions 271 and 371 also include bulged portions 264A and 364A.
