Ring 62a periphery bottom it is roughly the same with the lower end of flange 44 of upside.On the other hand, as shown in figure 5, that will control
In the state that arm 62,62 keeps horizontal, the top of the periphery of ring 62a is upper than upper surface, that is, upper flange 41 of slider body 4
The upwardly projecting predetermined size 62t in surface.Thus, the upper surface of slider body 4 formed than left and right arms 62,62 ring 62a
Upper surface it is low.In addition, pulling-on piece main body 61 is frame-shaped.
In the pull head 3 of the first embodiment of aforementioned present invention, due to by the maximum of the up and down direction on 4 top of slider body
Thickness t is set as diameter 5d (such as 0.9mm) < t < 2.5mm of support shaft 5, therefore can fully reduce relative to one
The protrusion length upwardly projecting to zipper strip 21,21, and then can fully reduce overhang.
In addition, the top of the slider body 4 about pull head 3, by by the thickness of the up and down direction of its left and right end portions preceding
Rear direction middle part forms most thick, make support shaft 5 from the formation most thick part is prominent to side, so as to ensure to make
For the intensity (thickness) of support shaft 5.On this basis, the top about the slider body 4 of pull head 3, by its upper surface be set as from
Front end is towards the acclivitous ramp 41s of front-rear direction middle part, and the front end of its lower surface is also set as lower inclined plane
41u, therefore can fully reduce relative to the upwardly projecting overhang of a pair of of zipper strip 21,21.
Moreover, ring 62a of the pull head 3 due to a pair of of the arm 62,62 for forming the upper surface of slider body 4 to keep than level
Upper surface it is low, therefore can reduce relative to the upwardly projecting overhang of a pair of of zipper strip 21,21.
In addition, slider body 4 is formed as due to left and right side 41c, 41d of upper part with from front-rear direction middle part court
It is gone to front 41a and gradually leans on middle part in the lateral direction, therefore, the left and right width of the front-rear direction middle part of slider body 4
Size can be using a pair of of chain denture 22,22 by required minimum dimension, and the top that can reduce slider body 4 is opposite
In the upwardly projecting amount of a pair of of zipper strip 21,21.
In this way, for the pull head 3 of first embodiment, due to that can reduce relative to a pair of of zipper strip 21,21 to upside
Overhang outstanding, therefore impression relatively thin on the whole can be brought.
As shown in Figure 10, applying the pull head 3 of two first embodiment of the invention, second embodiment of the invention
Zipper 1, so that the opposite state in the front end of two pull heads 3,3 is installed on a pair of of chain dental strip 2,2.Before and after two pull heads 3,3
Between and between a pair of of chain dental strip 2,2 be formed with gap 2a (in more detail, between a pair of of chain denture 22,22).
If two pull heads 3,3 is made to be close, gap 2a narrows.Moreover, if abutting against two pull heads 3,3, gap
2a disappears, and as shown in figure 11, the front end face of pull head 3 is in contact, so that the sealing under a pair of of chain dental strip 2,2 closed states mentions
It is high.Moreover, because the front 41a of the upper flange 41 of each pull head 3,3 is parallel with left and right directions linear, and including preceding
Front end face including the 41a of side is the vertical guide parallel with up and down direction, therefore is easy to maintain the front end face of pull head 3 against each other
State.
By the way, if two pull heads 3,3 is made to be close, as shown in Figure 10, a pair of of zipper strip 21,21 is located at two
The part (hereinafter referred to as " part near pull head " of a 3,3 left and right sides of pull head.) it is in arc-shaped in a manner of heaving outward
Deformation.The deformation significantly occurs when two pull heads 3,3 as shown in figure 11 abut against.Moreover, user usually with slightly towards
The mode that upside lifts pulling-on piece 6 keeps pull head 3 mobile, therefore partially becomes slightly near the pull head in a pair of of zipper strip 21,21
Such shape is swelled upwards.Moreover, in zipper 1, the side opposite with side edge part relative to each other of a pair of of zipper strip 21,21
The objects such as clothes are fixed in, therefore becomes side further up near the pull head in a pair of of zipper strip 21,21 and swells that
The shape of sample.Allow the protuberance shape be two pull heads 3,3 one of intended shape.If each pull head 3 hinders the protuberance,
Two pull heads 3,3 are unable to maintain that abutting state and separate front and back, to be unable to ensure sealing.But due to by 3 top of pull head
Left and right side 41c, 41d be formed as with from front-rear direction middle part towards front 41a and gradually by intermediate in the lateral direction
Portion, therefore, compared with left and right side 41c, 41d of for example a pair of of pull head 3 are in the linear situation parallel with front-rear direction, one
To being partially allowed to swell upwards near the pull head in zipper strip 21,21.Moreover, in each pull head 3, due to upper flange 41
The edge part of front of lower surface be set as lower inclined plane 41u, 41u, 41v, 41v, therefore with for example by the following table of upper flange 41
Face is set as the case where pull head of simple horizontal plane and compares, be partially allowed near the pull head in a pair of of zipper strip 21,21 to
Top protuberance.
The first variation of the pull head 3 of first embodiment of the invention is as shown in Figure 12 and Figure 13, in the upper table of upper flange 41
Ornamental sheet material 7 is pasted on face, this point is different from the pull head 3 of first embodiment.
Sheet material 7 is made of upper surface is applied with desired color and printing word, figure, symbol etc..
The present invention is not limited to above embodiment, can suitably be become within the scope of its spirit
More.For example, the maximum gauge size t of the up and down direction on 4 top of slider body has been set as t < by the pull head 3 of present embodiment
2.5mm, however, it is not limited to this also can be set to t >=2.5mm, and in this case, the upper surface of slider body 4 forms to obtain ratio
The upper surface of a pair of of ring 62a, 62a of a pair of of arm 62,62 that level is kept are low.
In addition, the front 41a of the pull head 3 of present embodiment is in parallel with left and right directions linear, but be not restricted to that
This, is also possible to the other shapes such as the shape heaved in arc-shaped.
Moreover, the left and right end portions of the slider body 4 in present embodiment, all have flange 44 on top and lower part, still
It is not limited to this, is also possible to that only there is flange 44 in the left and right end portions of 4 lower part of slider body, and on 4 top of slider body
Left and right end portions do not have flange 44.
In addition, the shape of the upper flange 41 of the pull head 3 of present embodiment is different from the shape of lower wing plate 42, but and it is unlimited
In this, the shape of upper flange 41 can also be made consistent with the shape of lower wing plate 42.
