Further, the rear ends of the pair of leg portions 31b and 31c are located further forward than the front ends of the pair of element rows 12 and 12. Therefore, the pair of leg portions 31b and 31c and the pair of element rows 12 and 12 are in the front-rear direction. There is a state of the gap.

The pair of raised walls 32 and 32 are extended all the way along the circumferential direction of the housing 31, and are formed at the central portion in the inner and outer directions on the lower surface of the housing 31. Therefore, on the upper and lower surfaces of the container body 31, two non-contact surfaces 31s and 31s which are in contact with the upper and lower wing plates 21 and 22 are formed on the inner side and the outer side of each of the raised walls 32, respectively. More specifically, in the inner and outer directions, each of the raised walls 32 is formed on the outer side of the inner peripheral edge other than the front end portions of the pair of leg portions 31b and 31c, and is located further inside than the outer peripheral edge. The front end portions of the portions 31b and 31c are formed over the entire range of the inner circumference and the outer circumference.

Further, each of the end wall portions 32c and the leg portions 31b and 31c is a vertical surface that is continuous in the vertical direction on the side of the left and right side surfaces on the side of the passage 31j. Further, the left and right vertical faces are in close contact with each other in a state where the inlet portion 31i is closed.

Further, between the adjacent partition wall portions 32a and 32b, a recessed portion 32h recessed toward the side of the housing 31 is formed, and both ends of the recessed portion 32h in the extending direction are closed by the end wall portion 32c. Therefore, a recessed portion 32h is formed inside the two partition wall portions 32a and 32b and the two end wall portions 32c and 32c, and the recessed portion 32h is formed at a central portion in the inner and outer directions of the swelled wall 32. Further, the grease 3b is housed in the recessed portion 32h. The capacity of the grease 3b is smaller than the capacity of the recessed portion 32h. More specifically, the upper recessed portion 32h accommodates only the grease 3b to the upper side. The upper surface of the raised wall 32 is at a low position. Further, the grease 3b is preferably accommodated in the entire length of the recessed portion 32h in the extending direction, but may be accommodated in one of the extension lengths.

Each of the stoppers 33 has a length that protrudes from the housing 31 in the vertical direction, and is longer than the length of the raised wall 32 that protrudes from the housing 31 in the vertical direction, and faces the front surface of the slider 2. In addition, each of the stoppers 33 is formed at the front end portion of the storage body 31 so as to be in a state of colliding or approaching the front surface of the slider 2 in a state in which the connection post 23 is housed in the column accommodation hole 31h. Further, the width of the inner and outer directions of each of the stoppers 33 is wider than the width of the inner and outer directions of the swelled wall 32.

In the case where the stopper 3 of the first embodiment of the present invention does not completely close the pair of element rows 12 and 12 as shown in Figs. 1 and 2, the inlet portion 31i is opened.

On the other hand, when the stopper 3 of the first embodiment of the present invention completely closes the pair of element rows 12 and 12 as shown in FIG. 6, the connecting post 23 of the slider 2 and the housing 31 are provided. A gap is formed between the inner surfaces thereof along the entire circumference in the circumferential direction, and the front surface of the slider 2 (the pair of flaps 21, 22) collides with the stopper 33. Further, the stopper 3 according to the first embodiment of the present invention closes the inlet portion 31i by abutting against the end wall portions 32c and 32c and the pair of leg portions 31b and 31c by one of the ridge walls 32. Further, as shown in Figs. 7 and 8, the stopper 3 according to the first embodiment of the present invention sandwiches the stopper main body 3a between the upper and lower flaps 21, 22, and is held by the upper and lower flaps 21, 22. The upper and lower ridge walls 32, 32 are elastically deformed by the rubber elasticity of the stopper body 3a. More specifically, the adjacent partition wall portions 32a and 32b and the pair of end wall portions 32c and 32c of the respective raised walls 32 are elastically deformed to be in close contact with the upper and lower flaps 21 and 22. More specifically, the stopper 3 of the first embodiment of the present invention has a recessed portion as compared with the stopper having the raised wall having the structure of the recessed portion 32h. 32h, the pair of partition walls 32a and 32b are easily elastically deformed in the inner and outer directions, so that the airtightness can be improved.

Further, by elastic deformation, the capacity (accommodation space) of the grease 3b of the recessed portion 32h between the adjacent partition wall portions 32a and 32b becomes small, and the grease 3b adheres to the upper and lower flaps 21, 22, or enters. Between the partition wall portions 32a, 32b and the upper and lower flaps 21, 22, the frictional resistance when the slider 2 is moved is reduced, thereby improving durability. Further, in the case where the zipper F including the stopper 3 of the first embodiment of the present invention is used, for example, in a waterproof suit and used in water, there is a case where a pair of chain rows 12, 12 are completely completed. When the water pressure changes in the closed state, the respective raised walls 32 move accordingly. However, each of the raised walls 32 doubles the airtightness by the pair of partition walls 32a and 32b, and the grease 3b which enters between the upper and lower flaps 21 and 22 and the pair of partition portions 32a and 32b also has Helps improve the airtightness.

Further, when the slider 2 is moved in order to pull apart the pair of element rows 12, 12, the grease 3b is coated and spread to the upper and lower surfaces of the upper and lower flaps 21, 22 or the partition portions 32a, 32b. Further, the partition walls 32a and 32b are elastically deformed on both sides in the inner and outer directions of the recessed portion 32h, so that the mobility of the slider 2 is improved.

In addition, when both ends of the recessed portions 32h are opened in the circumferential direction, the grease 3b leaks from the opening portion, and the capacity of the grease 3b is easily reduced. If the grease 3b is reduced to less than a certain fixed amount, the grease does not enter between the pair of flaps 21, 22 and the respective raised walls 32, and it is difficult to move the slider. However, since both ends of the extending direction (circumferential direction) of each recessed portion 32h are blocked by the end wall portion 32c, the grease 3b can be retained for a long period of time.

The stopper 3 of the second embodiment of the present invention is different from the stopper 3 of the first embodiment in that the recess 32h includes a plurality of recesses 32j, and the plurality of recesses 32j are opposite to each other. The receiving bodies 31 are arranged at intervals in the circumferential direction thereof; and the front end (rear end) of one of the stopper body 3a and the front end (rear end) of the leg portions 31b, 31c and the leading sprocket 13 of the corresponding element row 12 Connection; in other respects, it is identical to the stopper 3 of the first embodiment.

More specifically, each recess 32j is connected to the joint portion 31a constituting the housing 31. The pair of leg portions 31b and 31c are formed in a long hole shape elongated in the circumferential direction of the housing body 31. Further, grease 3b is accommodated in each recess 32j.
