Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a concealed zipper, and more particularly to a concealed pull button for an electromagnetic wave shielding article. [Prior Art] With the spread of the information technology industry in recent years, (4) The situation in which electronic equipment is protected from electromagnetic waves is increasing. In order to achieve this, an electromagnetic wave shielding article such as an electromagnetic wave shielding sheet or an electromagnetic wave shielding tube that blocks electromagnetic waves is used in a large amount, and the connection or switching portion of the joint existing in the product is sometimes operated by a zipper. As a technique related to a zipper capable of blocking electromagnetic waves, that is, a so-called electromagnetic wave shielding pull key, there is WO 2009/093678 (Patent Document 丨). Patent Document 1 discloses a concealed slide fastener for the purpose of improving the electromagnetic wave shielding performance of the joint portion when the electromagnetic wave shielding performance of the joint portion is insufficient in connection with the electromagnetic wave shielding material by the zipper. When the zipper is locked in the hidden zipper, the body of the slider is not exposed to the outside. In this document, it is described that the one side and the other side of the key cloth are directly crimped to each other in the middle portion, and are not held apart by the fastener element, thereby preventing electromagnetic wave shielding performance due to the shape of the element or the like. Deterioration. PRIOR ART DOCUMENT Patent Document Patent Document 1: WO 2009/093678 [Disclosure] Problems to be Solved by the Invention 154129.doc 201221080 Patent Document i is a concealed zipper for electromagnetic wave shielding products, and describes a key after zipper closure _The electromagnetic wave shielding between the joints is blocked, but there is no electromagnetic wave countermeasure against the gap between the (10) cloth and the sliding member on the side of the guide σ of the slider. Accordingly, one of the objects of the present invention is to provide a concealed zipper having a characteristic of ρ and breaking electromagnetic waves, which implements an electromagnetic wave countermeasure against a gap between a chain cloth and a slider which is formed on the inlet side of the slider. The technical means for solving the problem is that in the zipper in which the two sliding members are mounted opposite to each other on the side of the introduction port, that is, the so-called head-fit zipper, when the inlet end sides of the two sliders abut each other The zipper becomes closed. The present inventors have found that the prior art head-engaging type slider does not consider the application to the electromagnetic wave shielding article. When the two sliders abut each other, a gap is formed between the end portions of the inlet port, causing electromagnetic wave leakage. Further, it has been found that since electromagnetic waves easily pass through the linear slits, even a small gap becomes a cause of deterioration of the performance of the electromagnetic wave shielding article; and the elimination of the slit contributes to the improvement of the reliability of the electromagnetic wave shielding product. Further, by fitting the slider head of the same shape, the number of parts can be reduced, and inventory management becomes easy. The present invention is based on the above findings and is determined by the following contents. An aspect of the present invention is a concealed zipper, comprising: a pair of chain belts having electromagnetic wave shielding properties and comprising a chain cloth having a curved portion on one side edge; and a fastener element mounted along the curved portion; And a pair of sliding members, which are slidably mounted on the pair of chain belts for disengaging each of the fastener elements; and the pair of sliding members respectively have electromagnetic wave shielding characteristics and have: lower 154129. Doc 201221080 wing; left and right side walls erected along the side edges of the left and right sides of the lower wing; first and right side guides extending from the upper end of the left and right side walls in a direction close to each other; a guide post between the left and right first side guides of the lower wing plate; a second side guide plate disposed on the guide post and protruding toward the engagement opening; and the side wall of the lower wing plate and the left and right sides a sprocket guiding passage of the guiding sprocket surrounded by the first side guide; and a part of the chain cloth may be outwardly guided from the sprocket guiding passage between the first side guide and the second side guide a slit S extending out; the pair of sliding members are connected to the side of the inlet The opposite direction is attached to the chain belt, and the front end surface of the lower wing of the one of the sliding members is formed to be in close contact with the front end surface of the lower sliding member of the other sliding member. In one embodiment of the concealed zipper of the present invention, the front end surface of the lower wing of one of the sliders may be in close contact with the front end surface of the lower slider of the other slider between the left and right first side guides. In another embodiment of the concealed zipper of the present invention, the front end surface of the lower flap of one of the sliders has the same shape as the front end surface of the lower flap of the other slider, and the left and right shapes are in opposition. In still another embodiment of the concealed slide fastener of the present invention, the front end surface of the lower flap of the one slider has an uneven shape so as to overlap in the up-and-down direction when it is in close contact with the front end surface of the lower flap of the other slider. In another embodiment of the hidden zipper of the present invention, under each slider

EFFECT OF THE INVENTION 154129.doc 201221080 Case By using the slider of the present invention for the head-fit type pull key, since the front end faces of the lower flaps of the two sliders are in close contact with each other when the zipper is closed, the electromagnetic wave passage can be blocked. Therefore, it is possible to suppress the leakage of electromagnetic waves from the sliding members, and the embodiment according to the shape of the left and right ends of the 刖 end faces of the γ-wings can be used to manufacture the head-fit zipper using the same slider, so that the parts can be reduced. The number of pieces and inventory management has also become easier. In particular, according to the embodiment in which the front end surface of the lower blade has an uneven shape which is overlapped with the other end faces of the lower blade of the counterpart slider, the front end faces of the two sliders are not confirmed even when the zipper is locked. When the contact is made, a gap is formed between the two, and the overlapping portion fills the gap to block the effect of the electromagnetic wave path. Further, the front end surface of the lower wing plate has a pair of locking plates and a receiving portion, the locking plate is thinner than the lower wing plate, and the upper surface of the locking plate is located lower than the upper surface of the lower wing plate The lower surface of the locking plate is located at a higher position than the lower surface of the lower wing plate, and the receiving portion is formed into a groove shape corresponding to the shape of the locking plate, and two sliding members can be obtained. When the front end faces of the flaps are in close contact with each other, the resistance to the torsion of the shaft in the front-rear direction or the left-right direction is increased. Therefore, even when a twist or the like is applied to the electromagnetic wave shielding product, it is difficult to form a gap between the sliders, and the electromagnetic wave shielding effect can be maintained. . [Embodiment] One embodiment will be described below with reference to the drawings, and the embodiments of the present invention will be described. 154129.doc 201221080 The concealed zipper of the present invention is used in the ancient genre.

The hidden zipper itself is well-known as described in WO 2009/093678 (Patent Document 1), and one side edge of the key cloth is bent in a substantially U-shape to form a curved portion, and a fastener element is attached along the curved portion. The sprocket of the pair of chain belts is buckled by the sliding of the slider, thereby achieving the zipper switch. In the present embodiment described below, 154129.doc 201221080 has a chain attached to the key fabric that ejects the synthetic resin along the side edge of the key fabric to form a chain of a plurality of fastener elements, but is not particularly limited to this implementation. form. The chain-to-chain cloth may be attached to a chain in which a linear sprocket formed in, for example, a coil shape or a mineral tooth shape is sewn along the sprocket attachment edge portion. The configuration of the chain belt to which the present invention is applied is of course not particularly limited, and it is preferable to use the hidden zipper chain belt disclosed in P(10)p 2G_59586. Specifically, the key tape has a pair of left and right chain cloths including a chain main body portion and a fastener element mounting portion disposed on one side edge of the chain main body portion, and the main constituent yarns constituting the chain cloth are conductive wires. The above chain cloth has electrical conductivity capable of shielding electromagnetic waves. Moreover, the pair of chain cloths have a conductive bond portion which is in close contact with the other party's chain cloth when the stitches are twisted, and the element teeth in the meshed state are arranged in the chain cloth dense portion. When it is in close contact, it is covered by the chain cloth dense portion disposed on one of the chain cloths. Furthermore, the contents of PCT/Jp 2〇〇9/〇59586 are hereby incorporated by reference herein in its entirety in its entirety. The slider used in the zipper of the present invention has electrical conductivity capable of shielding electromagnetic waves. Such a slider can be produced by die casting or injection molding using a conductive metal or synthetic resin. As the metal having conductivity, as the chain cloth, gold, silver, copper, ingot, tungsten, ruthenium, rhodium, iron, or a metal of one type may be mentioned, and as a synthetic resin having conductivity, it may be mentioned Alkyne, polypyrrole, polythiophene or polyaniline. Further, after the slider is formed using another material such as a resin, the metal may be plated. As described below, the sliding parts of complex shapes can also be self-complexed and the group 154129.doc -9-201221080 is equipped with 0, and 'the same can also be used with the characteristics of electromagnetic shielding properties. 'Concealed zipper middle key cloth - The side edges are bent, and when the pull key is locked, the bent portions of the pair of key cloths are directly crimped without being separated by the key teeth, so that the shielding properties are substantially unobstructed as long as the chain cloth has electromagnetic wave shielding properties. The squat key does not have electromagnetic waves in the sliding part of the present specification. 'The sliding direction of the sliding member is set to the front-rear direction, and the sliding member makes the key teeth row and slide and the direction of sliding is set to the front, so that the key teeth are separated and slid. The direction is set to the rear. The front end of the slider is the head of the slider. Further, the direction orthogonal to the upper and lower blades is the vertical direction, and the direction from the lower blade toward the upper blade (the first side guide) is set to the upper side from the upper blade toward the lower blade: The direction parallel to the upper and lower blades and perpendicular to the sliding direction of the slider is the left-right direction. When sliding the slider forward when viewed from above, the right side of the direction in which the slider travels is the right direction, and the left side of the traveling direction is the left direction. Further, in the slider, the opening σ before the separation of the job is referred to as an introduction port, and the opposite side, that is, the opening after the element is meshed, is referred to as a meshing port. <First Embodiment> A slider for electromagnetic wave shielding slide fastener according to a third embodiment of the present invention will be described. Fig. 1 is a perspective view of a slider (10) of the embodiment. Referring to Fig. 1, the basic structure of the slider (10) of the present embodiment includes a lower blade (13), and left and right side walls (Ma, along the side in the left-hand direction of the lower blade (13) and the edge are erected. 14b); left and right i-side guide plates (15a, l5b) extending from the upper ends of the left and right side walls (14a, Ub) in the direction in which they approach each other; near the introduction port from the lower wing plate (13) The left and right central portions face the engagement opening and 154129.doc -10- 201221080 is disposed between the left and right first side guide plates (15a, 15b); the guide post (21) is disposed on the guide post (21) a second side guide (22a) having a surface 'at least at least toward the left and right first side guides (15a, 15b) and the engagement opening; and a cantilever-shaped handle mounting portion for supporting the pull tab (25) (23) » Further, in the present invention, the first side guide also appears as an upper wing. The lower wing plate (13), the left and right side walls (Ma, 14b), the guide post (21), the first side guide plates (15a, 15b), and the second side guide plate (22a) are formed in a plan view substantially Y The space of the font becomes the sprocket guiding passage (17) of the fastener element mounted on the chain belt. One of the states in which the meshing heads (45) of the fastener elements are opposed to each other is inserted into the introduction port of the slider (10), and the slider (10) is moved forward, thereby engaging the left and right fastener elements. In the state (locked state), the engagement port of the slider (1 〇) is pulled out. The folded portion of the chain cloth extends outward from the slit S between the first side guides (15a, 15b) and the second side guide (22a). The lower wing plate (13) has a substantially trapezoidal plate shape, and the width in the left-right direction is gradually narrowed from the front end edge (13a) of the introduction port side to a position of approximately 3/4 of the total length, and then the end edge of the meshing port side (to the end edge of the meshing port side) 13b) is basically the same. Further, the upper surface of the lower blade (13) is formed to be parallel to the lower surface of the first side guides (15a, 15b). Thereby, the opposing fastener elements inserted into the element guide passage (17) of the slider (10) from the introduction port are smoothly sprayed together with the sliding of the slider (10).

On the upper surface of the inlet side of the second side guide (22a), a thick portion formed on the upper surface of the inlet side of the first side guide (15a, 15b) is formed ( 15e) thicker thick portion (22b). The thickness of the thick portion (22b) is maintained until the leading end side of the second side guide (22a), and the introduction side of the second side guide (22&) The end surface (27) is formed with a high inclined wall that continuously protrudes forward as the self-guide column (2 turns) upward, whereby even the fastener element inserted from the introduction port is first in a standing state due to strong lateral pulling force. In the case of the case, it is possible to enter the element guide passage (17) while being smoothly poured by the inclined wall, and finally can be substantially parallel to the lower blade (13) in the element guide passage (17). The upper surface of the guide post (21) is provided with a tab-type mounting portion (23) having a one end fixed in a cantilever shape and extending in the sliding direction. The drawing is not shown in Fig. 1 154129.doc •12· 201221080 does not 'but prepare a pull tab (25) having an annular portion at one end, through which the pull tab can be rotatably mounted to Pull tab mounting portion (23). Fig. 3 shows a case where the pull tab (25) shown by a broken line is attached to the pull tab mounting portion (23). The front end portion of the pull tab mounting portion (23) is shown in Fig. 3. The slider (25) is not easily detached from the tab attachment portion (23). The slider (1) of the present embodiment is composed of two parts except the tab (25). Each part can be manufactured by die-casting or injection molding using a mold. By using two parts, it is possible to produce a complicated structure in which the former slider which is integrally formed is not restricted by the mold structure. For example, the degree of freedom of the shape of the second side guide (22a) can be increased by providing two parts, and the second side guide (22a) having a large leftward and rightward projection can be formed. Specifically, the distance from the center line of the right and left sides of the slider (10) to the left and right outermost ends of the second side guide (22a) may be opposite to the center line to the side wall (14a, 14b) of the slider (10). The distance from the inner side surface of the mouth side of the mouth is 0.8 times or more, preferably ι·〇 or more. Therefore, the sprocket can be guided by the second side guide (22a) and can be smoothly introduced to the slider (10) by applying a weak force to the zipper when the zipper is locked. Slide operation. Fig. 2 is an exploded perspective view of the slider (1) of the embodiment. The slider (10) of the present embodiment includes a slider body portion (11) having a lower blade (13), left and right side walls (14a, 14b), and left and right first side guides (15a, 15b), And two parts of the upper plate portion (12) of the slider having the second side guide (22a) and engaged with the slider body portion (π). In the present embodiment, the guide post (21) and the tab attachment portion (23) are provided on the slider upper plate portion (12), but these may be provided on the slider body portion (11). And any of the above-mentioned sliders 154129.doc • 13· 201221080 upper plate portion (12). Referring to Fig. 2, a projecting portion (16) is erected at a center portion of the left and right side of the lower blade (13), and the upper plate portion (12) has an introduction port side of the guide post (21). The end surface and the rectangular opening portion of the end surface (27) of the second side guide (22a) on the side of the introduction port side are formed in a rectangular shape, and a groove portion having a shape conforming to the shape of the protruding portion (16) is provided ( twenty four). Further, on the upper plate portion (12), a pair of leg portions (26) are protruded toward the front from the left and right side walls of the guide post (2丨) located at the left and right of the opening portion of the groove portion (24). . The slider body portion (11) and the upper plate portion (12) are combined by the state in which the protruding portion (16) is engaged with the groove portion (24), and the method of engaging the two parts is as long as two parts are used. The separation is not particularly limited, and in the present embodiment, the slider main body portion (11) and the upper plate portion (12) are combined by the following method. The protruding portion (16) includes: a substantially T-shaped base portion (16a) extending in the left-right direction and the engagement opening side; the base portion (16a) is erected on the base portion and has a smaller width than the base portion (16a) The upright portion (16b) having a substantially τ shape in plan view; and the rib (16c) having a substantially T-shaped shape in a left plan view that is erected on the upright portion (16b) and larger in width than the ridge portion (16b). The end surface of the rib (16c) is engaged with the upper plate portion (12) so as to be flush with the end surface (27) of the second side guide (22&). Inclined surface. On the other hand, the groove portion (24) has an internal structure conforming to the shape of the protruding portion (16) so as to be engageable with the protruding portion (16), and is oriented toward the front from the rear of the protrusion 1 (16). The portion (24) slides, whereby the groove portion (24) is engaged with the 154129.doc -14-201221080 protruding portion (16). Thereafter, the pair of leg portions (26) are pressed toward the inner side so that the opening portion of the groove portion (24) is blocked, whereby the protruding portion (16) is fixed to the groove portion (24). Fig. 3 shows the engagement state of the protruding portion (16) and the groove portion (24). Returning to the left and right shapes of the front end face (13c) of the lower blade (13) in Fig. 1, there is a relationship. Specifically, the front end surface (13e) has a base surface (13d) formed on substantially the same surface as the front end portions (14c, I4d) of the left and right side walls. The base surface (13d) has a flat surface that linearly connects the left and right side walls to each other in the left-right direction. The front end surface (13c) has a locking plate (31) that protrudes forward from the base surface (13d) at a left half of the center in the left-right direction; and a right half of the opposite side to the base surface (13d) The accommodating portion (32) provided below and conforming to the shape of the above-mentioned locking plate (3 丨). In other words, the base surface (13d) defines the boundary between the above-described locking plates (31, 61a, 61b, 71) and the accommodating portions (32, 62a, 62b' 72). Thereby, the heads of the two sliders (1 相同) of the same shape are abutted against each other to make the zipper in a completely closed state, and the front end faces (13c) of the flaps (13) under the sliders (10) are in close contact with each other' The electromagnetic wave path in the up and down direction is blocked. The locking plate (31) is thinner than the lower wing plate (13), and the upper surface of the locking plate (31) is located lower than the upper surface of the lower wing plate (13), and the lower surface of the locking plate (31) Located higher than the lower surface of the lower wing (13). Further, the upper surface of the accommodating portion (32) corresponding thereto is lower than the upper surface of the lower wing plate (13), and the lower surface of the accommodating portion (32) is formed higher than the lower surface of the lower wing plate (13). Position, and become a trough. As a result, the front end surface (13c) of the lower blade (13) overlaps in the up-and-down direction when it is in close contact with the front end surface of the lower blade of the counterpart slider. Therefore, even if the base surface (13d) of the front end faces (13c) of the two sliders is not abutted against each other when the zipper is locked, a gap is formed between the two, and the gap can be filled by the overlap 154129.doc 201221080 And block the path of electromagnetic waves. Further, when the front end faces (13c) of the two lower blade lower flaps (13) are in close contact with each other, the resistance to the torsion of the shaft in the front-rear direction or the left-right direction becomes high, so that even when a twisting action or the like is applied to the electromagnetic wave shielding product, It is also difficult to create a gap between the sliders, and the electromagnetic wave shielding effect is not easily reduced. Moreover, the upper surface of the locking plate (31) and the receiving portion (32) is formed lower than the upper surface of the lower wing plate (13), so that the locking plate (31) and the receiving portion (32) are difficult to contact and inserted into The sprocket guides the sprocket of the passage so that it does not interfere with the sliding of the slider. The locking plate (31) has a substantially trapezoidal shape in which the width of the left and right sides is gradually narrowed toward the front. By this, when the sliding members (10) are brought close to each other to close the zipper, even if the positions of the two are slightly deviated from the top, bottom, left, and right, the engagement between the locking plate (31) and the accommodating portion (32) can progress. Correct the position to the exact position and get the connected status. In order to achieve a smooth fitting action, the locking plate (31) is preferably a chamfered one. Fig. 4 is a view showing a state in which a part of the zipper is opened in plan view in a head-fit type electromagnetic wave shielding zipper (40) including the slider (1) of the embodiment. The chain cloth (42) has a bent portion (43) on one side edge, and a plurality of sprocket teeth (41) are mounted along the curved portion (43). The state in which the row of the fastener elements (41) is mounted on the chain cloth (42) is referred to as a key belt. The key cloth (42) used in the present embodiment is made of a conductive material in the key cloth, and the chain belt used in the present embodiment can be described in the first embodiment of PCT/JP 2009/059586. The edge of the chain cloth (42) is hidden below and will not be seen. In the figure, the position indicated by the two-point lock line indicates that it exists hidden underneath. Further, the broken line indicates the pull tab (25). The sliders (10) having the same shape are inserted between the pair of chains so that the heads, i.e., the inlets, are facing each other 154129.doc •16·201221080. As the sliders (1〇) slide in the direction in which they are close to each other, the fastener elements (41) constantly mesh with each other, and when the heads of the two sliders (1〇) abut each other, the zipper is in a completely closed state. Fig. 5 is a view showing a state in which the zipper is completely closed in plan view in the electromagnetic wave shielding concealed zipper (4 〇) having the slider (10) of the present embodiment, and Fig. 6 is a view of the state in a bottom view. Further, Fig. 7 is an α_α of Fig. 6, a line sectional view, and Fig. 8 is a sectional view of the Β-Β' line of Fig. 6. Referring to Fig. 5 and Fig. 6, it can be seen that the sprocket (41) is hidden from the bottom when the zipper is completely closed, so that it cannot be seen from above. At this time, the folded portion of the chain fabric is not creased by the bulging portion (not shown) protruding from the engaging leg portion (44) of the fastener element, so that no gap is formed between the one folded portion and the other folded portion. The leakage of electromagnetic waves from the meshing portion of the sprocket is blocked. Referring to Figures 7 and 8, it can be seen that when the heads of the two sliders (10) abut each other, the front end faces (13c) of the lower blade (13) are in close contact with each other. Further, referring to Fig. 8, it is understood that the front end faces (13c) of the lower blade (13) overlap each other in the vertical direction. Further, as can be seen from Fig. 7, the front end portions (14c, 14d) of the left and right side walls (14a, 14b) are perpendicular to the front-rear direction 'as the base surface of the front end surface (13c) of the two sliders (1〇) (13d) When abutting each other, the front end portions (14c, Md) of the left and right side walls (14a, 14b) abut each other. Further, as can be seen from Fig. 7, the end face of the second side guide (22a) on the inlet side The front ends of (27) are also closely connected to each other. In this way, not only the lower flap (13) but also other portions of the head of the slider can be closely attached, whereby the electromagnetic wave shielding effect can be further improved. Here, the base surface (13d) of the slider of the present embodiment is preferably located at the front end portion (14c, 14d) of the side wall, the front end surface of the first side guide plate (15a, 15b), and the side of the 154129.doc 17 201221080 2 side. The guide plate (22a) protrudes at the same position in the front end portion of the front end portion, or protrudes further toward the front side. With such a configuration, the shape of the front end portion of the side wall (14e' 14d), the first side guide, and the front end of the second side guide can be made to 'bend the front end surface (1) of the lower wing (13) to each other. Close contact. In the first embodiment, the base surface (丨3d) formed as the slider is located at the same position at the front end portion (14c Μ < 1) of the side wall, the front end surface of the first side guide and the second side guide. The front end portions (14c, 14d) of the left and right side walls (14a, 14b), the front end faces of the first side guide plates (15a, 15b), and the front end faces of the second side guide plates (22a) may also be combined with the lower wing plates (13). Similarly to the front end surface (13c), the close contact state is achieved by the uneven shape of the right and left. In addition, when the two sliding members are abutted by the head fitting, the front end portions (14c, Md) and the first side guide are not blocked in order to prevent the front end faces (i3c) of the lower flaps (13) from being in close contact with each other. At least one of the front end faces of the plates (15a, Mb) and the front end faces of the second side guide plates (22a) may be any shape in which the sliders are fitted to each other. In this case, the base surface (13d) does not have to be located at the front end portions (14c, 14d) of the side walls, the front end faces of the first side guide plates (15a, 15b), and the front end faces of the second side guide plates (22a). In the second embodiment, the electromagnetic wave shielding slide fastener (50) according to the second embodiment of the present invention will be described. Fig. 9 is a perspective view of the slider (50) of the embodiment. The same components as those of the first embodiment are denoted by the same reference numerals, and their structures and functions have been described, and the description thereof will be omitted. The following implementations are also the same as 154129.doc • 18· 201221080. The second embodiment differs from the first embodiment in the shape of the front end surface (13c) of the lower blade (13). In the present embodiment, the front end surface (13c) of the lower blade (13) is a flat surface that is perpendicular to the front-rear direction. In the present embodiment, the front end surface (13c) does not have irregularities, that is, includes only the base surface (13d), but the lower end plate (13) _ front end surface (13c) has a right-to-left relationship, and the same shape The heads of the sliders (50) abut each other such that the front end faces (13c) of the lower flaps (13) of the slider (50) are in close contact with each other when the zipper is in the fully closed state. The front end portions (14c, 14d) of the left and right side walls (14a, 14b) are located on the same plane as the front end surface (13c) of the lower wing panel (13), and when the heads of the two sliders (5〇) abut each other The front ends (14c, 14d) of the left and right side walls (14a, 14b) are in close contact with each other. <Third Embodiment> Next, a slider (60) for an electromagnetic wave shielding slide according to a third embodiment of the present invention will be described. Fig. 10 is a perspective view of the slider (6〇) of the embodiment. The third embodiment is also the same! Similarly, in the same manner, the front end surface (13c) of the lower blade (13) has a right-to-left relationship, and the heads of the two sliders (60) of the same shape abut each other to make the pull key fully closed. The front end faces (13c) of the lower flaps (13) of the slider (60) are in close contact with each other. However, the specific shape is different from that of the first embodiment, and therefore, the difference will be described below. In the present embodiment, the front end surface (13c) of the lower blade (13) has two locking plates (61a, 61b) and housing portions (62a, 62b) having different heights. As a result, the front end face (13c) of the lower wing plate (13) has two pairs of latching plates and accommodates 154129.doc • 19-201221080. Specifically, the upper half of the front end face (13c) is formed. a latching plate (61a) that protrudes forwardly from the left side and a retaining portion (62a) that is recessed rearward and that conforms to the shape of the latching plate (61a) over the right half thereof. The lower half of the surface (13c) is formed with a locking plate (61b) which is provided to protrude forward from the right half thereof, and a leftward half of the left side thereof and recessed rearwardly and in the shape of the above-mentioned locking plate (61b) Consistent housing (62b). The upper surface of the upper locking plate (61a) is located on the same plane as the upper surface of the lower wing (13), and the lower surface of the lower locking plate (61b) is located on the lower surface of the lower wing (13). On the plane. Also in the present embodiment, similarly to the first embodiment, when the front end surface (13c) of the lower blade (13) is in close contact with the front end surface (13c) of the lower blade (13) of the counterpart slider, the vertical direction overlaps. When the zipper is locked, the front end faces (13c) of the two sliders (6 〇) do not abut each other and a gap is formed between the two, and the gap may be filled by the overlapping portion to block the passage of the electromagnetic wave. The locking plates (61a, 61b) have a substantially trapezoidal shape in which the widths of the left and right are gradually narrowed toward the front, and the advantages are as described in the first embodiment. The front end of the front end portions (14c, 14d) of the left and right side walls (14a, Mb) and the end surface (27) of the second side guide plate (22a) on the side of the introduction port can be closely attached to the same as in the first embodiment. The description has been omitted in the first embodiment. <Fourth Embodiment> Next, a slider (70) for electromagnetic wave shielding and pulling of a fourth embodiment of the present invention will be described. Fig. 立体 is a perspective view of the slider (7〇) of the embodiment. Similarly to the first embodiment, in the fourth embodiment, the front end surface (13c) of the lower blade (13) has a right-and-left relationship, and the two I54129.doc -20-201221080 sliders (70) of the same shape are formed. When the heads abut each other to bring the zipper into a fully closed state, the front end faces (13c) of the lower flaps (13) of the slider (70) are in close contact with each other. However, the specific shape is different from that of the third embodiment, so the difference will be described below. In the present embodiment, the front end surface (13c) of the lower blade (13) has the same pair of locking plates (71) and the accommodating portion (72) as in the first embodiment. However, in the present embodiment, the left side is halfway. The upper surface of the locking plate (71) protruding toward the front is located on the same plane as the upper surface of the lower wing plate (13), and the lower surface of the locking plate (71) is located on the lower wing plate (13). ) The surface below the surface is the same. The accommodating portion (72) which conforms to the shape of the locking plate (7 丨) on the right half is recessed rearward. Fig. 12 is a view showing a state in which the two sliders (7 〇) facing each other are closely contacted by the head fitting for the slider (7 〇) of the present embodiment. The left side indicates the front and the right side indicates the close contact. The locking plate (71) has a substantially trapezoidal shape in which the width of the left and right is gradually narrowed toward the front, and the advantages are as described in the first embodiment. The front end of the front end portions (14c, Md) of the left and right side walls (14a, 14b) and the end surface (27) of the second side guide plate (22a) on the side of the introduction port are in close contact with each other in the same manner as in the first embodiment, and The description has been omitted in the first embodiment. The present invention has been described above based on the embodiments. However, the present invention is not limited to the embodiment, and various modifications can be made. In the above embodiments, the front end faces (13c) of the lower blade (13) are left and right. In the second embodiment, for example, in the second embodiment, the sliding member may be provided with a locking plate that protrudes from the base surface (13d) and is provided in another embodiment. The four-part (32) of the 154129.doc •21-201221080 shape of the above-mentioned locking plate (3丨) is provided on one of the sliders, and electromagnetic waves are shielded by being closely connected. Further, the present invention is a concealed zipper, but it is not intended to be invisible from the outside: it is used for the main purpose. It is also possible to use electromagnetic waves for the main purpose of blocking the pair of key cloths to intersect each other. Therefore, it is not necessary to arrange the slider of the present invention from the outside, and for example, the surface on which the keys are exposed (the back surface of the chain fabric) can be used as the outside. At this time, it is preferable to provide a tab mounting portion on the lower surface of the lower flap (13) to mount the tab. Further, the tab attachment portion is not limited to these and can be attached to any practical portion.
