Description of the invention (1) Detailed description of the invention [Technical Field] The present invention relates to heat exchange tubes of heat exchangers, such as metal plates for flat tube manufacturing, used for flat tube manufacturing, used as refrigerant circulation tubes of condensers for vehicle air-conditioning, etc. Tube and its manufacturing method. [Technical Background] Recently, for example, as a condenser for a vehicle air conditioner, as shown in FIG. 16, a pair of headers (1 1 0) (1 1 1) arranged parallel to each other at intervals are provided; two The ends are respectively connected to the side-by-side aluminum corrugated fins (1 13) connected to the tube header (1 1 0) (1); the inlet tube (1 14) connected to the upper end of the peripheral wall of the first tube header (U); The outlet pipe (1 I5) connected to the lower end of the peripheral wall of the second pipe header (1 1 1); the first compartment plate (11 6) provided inside the upper middle position of the first pipe header (1 10) ; And between the second compartment plate (1 17), the inlet pipe (1 14) and the first compartment plate (1 16) located in the middle lower position of the second tube header (1 1 1) Number of refrigerant circulation pipes (1 12), number of refrigerant circulation pipes (1 12) between the first compartment plate (1 16) and second compartment plate (1 17), second compartment plate (1 17) ) And the number of refrigerant circulation pipes between the outlet pipe (1 15) are sequentially reduced from above to form a channel group. The refrigerant in the gas phase flowing from the inlet pipe (1 14) is formed by the outlet pipe (Π 5). Until the liquid phase flows out, formed in the condenser to act as a snake for each channel group unit It is called a multi-flow type condenser (refer to Japanese National Fair Publication No. 3-4 5 3 00), which replaces the previous SerPentine type condenser. And ultra compact and widely used. 557235 5. Description of the invention (2) The refrigerant flow tube (112) of the above condenser is of course superior in heat exchange efficiency, because the required high-pressure gas refrigerant is introduced into it. In addition, in order to miniaturize the condenser, it is required that the wall of the tube through which the refrigerant flows is thin and the tube height is low. A flat tube used as a refrigerant circulation tube in such a case is known, for example, as disclosed in U.S. Patent No. 5,5 5 3,37,7. The flat tube system consists of a pair of flat walls facing each other; two side walls spanning the two side edges of the two flat walls; and two flat walls that extend simultaneously in the length direction and are provided at a predetermined interval from each other. The plurality of reinforcing walls are formed by two flat wall forming portions connected by a connecting portion, the plurality of reinforcing wall forming portions are integrally formed in a bulge shape on each flat wall forming portion, and the bulges are integrally formed on both side edges. One metal plate of the side wall forming portion is formed into a hair pin by bending the connecting portion according to the roll forming method, and is formed into a flat wall by the flat wall forming portion. At the same time, one side wall is formed by the connecting portion. Then, in a state where the reinforcing wall forming portions and the sidewall forming portions face each other, each is brazed to form the reinforcing wall and the sidewall on the other side. When manufacturing the above-mentioned conventional flat tube, when the metal plate is rolled into a thin pin shape by roll forming, the positions of the wall forming portions and the side wall forming portions are mutually opposed without offset, but In the case of brazing, when a pressing force is applied to bring the two flat wall forming portions closer to each other, the wall forming portion and the other side wall forming portion are reinforced with each other, and the position is shifted in the width direction of the flat wall forming portion. Therefore, when the brazing is performed in this state, the bonding areas of the mutually reinforcing wall forming portions and the mutual side forming portions are changed.

Description of the invention (3) Smaller or completely unjoined parts, resulting in a significant reduction in pressure resistance, and the problem of leakage of fluid flowing in a flat tube. The object of the present invention is to solve the above problems and provide a metal plate for manufacturing a flat tube, a flat tube, and a method for manufacturing the same, which can prevent between the mutually reinforcing wall forming portions and between the side wall forming portions after being bent into a thin pin shape. Position offset. [Inspiration of the invention] The first metal sheet for flat tube manufacturing according to the present invention is a metal sheet for manufacturing flat tubes, which is composed of a pair of flat walls facing each other, and a cross between two side edges of the two flat walls. 2 side walls; formed by a plurality of reinforcing walls which extend across the two flat walls and extend in the longitudinal direction at a predetermined interval from each other, and are provided with two flat wall forming portions connected by a connecting portion to bulge A plurality of reinforcing wall-shaped portions integrally formed on each flat wall forming portion, and a side wall forming portion integrally formed on both side walls with a bulge, and at least any one of the two side wall forming portions and all the reinforcing wall forming portions The front end portion and the front end portion of the wall forming portion opposite to the wall forming portion when the bent metal plate is thin-pin-shaped are formed with a system for preventing a shift in the widthwise direction of the flat forming portion. Jointer. According to the first metal plate for manufacturing a flat tube according to the present invention, the front end portion of at least one wall forming portion and the front end portion of the wall forming portion opposite to the wall forming portion when the bent metal plate has a thin pin shape are connected. An engaging portion is formed to prevent mutual displacement in the thickness direction of the wall forming portion. Therefore, for example, when a metal plate is bent into a thin pin shape by a roll forming method according to a rolling method, 557235 V. Description of the Invention 〇 This reinforcing wall forming portion and the side wall forming portion 5 are coupled to each other with the wall forming portion not displaced relative to each other. Further, the two flat wall forming portions are pressurized close to each other for brazing. In the direction, the thickness direction of the wall forming portions of the engaging portions formed by the engagement of the engaging portions is prevented from being shifted in the width direction of the flat wall forming portion, and according to the thickness direction of the other wall forming portions. That is, the position of the flat wall forming portion in the wide direction is prevented Therefore, when the brazing is performed in this state, the mutually reinforcing wall forming portion and the side wall forming portion become each of the flat tubes that are reliably brazed and manufactured across the entire length, and the pressure resistance is significantly improved. The term y of the so-called factory aluminum j in the manual refers to those that contain aluminum alloys in addition to pure aluminum. It is also shown in Figure 2 above Figure 4, Figure 7, Figure 7 and Figure 1: 3 above and below. The "k" or "k" metal plate according to the second flat tube manufacturing according to the present invention is a metal plate for the first flat tube manufacturing, at least in any one of the two side wall forming portions and any of the reinforcing wall forming portions. _ _Υ / · 刖 end face y is formed with one convex part and one of the wall forming part of the wall forming part, and L 刖 end face is formed with a convex part as a concave part for fitting. According to the present invention, the third flat tube manufacturing month 3 metal The plate is based on: The metal plate for flat tube manufacturing is set to have a cross-sectional area of the convex section cut at a plane perpendicular to the longitudinal direction of the wall forming section, and the height of the convex section is B to the wall forming section of the convex section. The maximum width in the thickness direction is C. The width in the thickness direction of the wall forming portion at the end of the convex portion is D. 6-557235 with the length direction of the wall forming portion. 5. Description of the invention (5) The recessed portion cut at a right angle. When the cross-sectional area is a, the depth of the concave portion is b, the maximum width in the thickness direction of the wall forming portion of the concave portion is c, and the width of the wall forming portion in the opening portion of the concave portion is d, and A &gt; a, A / a is satisfied. &lt; 1.5, B / b &lt; 1 • 5, C / c, &lt; 1.5 D / d &lt; 1.5. When the third metal plate for flat tube manufacturing is bent at the connection portion, the metal plate for flat tube manufacturing is thinly pin-shaped, and the reinforcing wall forming portion and the side wall forming portion are opposed to each other while being pressed into the convex portion into the concave portion. The convex part and the concave part are deformed according to the frictional forces on both sides of the convex part and the two sides of the concave part to prevent the convex part from falling off from the concave part. Therefore, the force of resisting the rebound is formed to keep the metal plate in the bending state and also becomes hard during welding. Do not use it to keep the mold in a bent state. As a result, when the flat tube is manufactured and the condenser is manufactured at the same time, the temporary fixing body formed by temporarily fixing the flat metal plate for bending the flat tube is easy to handle. 5 Furthermore, the manufacturing operation of the condenser becomes simple. In the third 丨 metal sheet for flat pipe manufacturing, the relationship between the cross-sectional area of the convex section and the cross-sectional area of the concave section is made A &gt; a In this case, the metal plate for flat pipe manufacturing is bent at the connecting portion as a thin pin. When the reinforcing wall forming part and the side wall forming part are opposed to each other and the convex part is pressed in the concave part, the frictional force 5 on both sides of the convex part and both sides of the concave part can prevent the convex part from falling off from the concave part. The ratio of the cross-sectional area and the cross-sectional area of the recessed portion is A / a &lt; 1.5 5 When Ay is over: 1.5, the metal plate for manufacturing the flat tube is bent by the connecting portion into a thin pin shape, so that the reinforcing wall forming portion and the side walls are formed. When the two parts are facing each other, the bending of the convex part and the concave part is 7- is significant, and the convexity is reduced.

The ratio of the cross-sectional area of the convex portion to the cross-sectional area of the concave portion is preferably 1.05 sA / asl.3. Similarly, the ratio of the height of the convex portion to the depth of the concave portion is B / b ^ 1.5, and the ratio of the maximum width of the convex ridge and the maximum width of the concave portion is C / cS1.5. When the ratio exceeds 1.5, buckling occurs in the convex portion (Buckling) and the like, thereby reducing the effect of preventing the convex portion from falling off from the concave portion. The ratio of the height of the convex portion and the depth of the concave portion is l.OsB / bsl.3, and the ratio of the maximum width of the convex portion and the maximum width of the concave portion is 1.0.C / c ^ l.3. Similarly, when the ratio of the width of the front end portion of the convex portion and the width of the opening of the concave portion is D / dsl.5 'when the ratio exceeds 1.5, the deformation of the concave portion becomes large, thereby reducing the effect of preventing the convex portion from falling off from the concave portion. The ratio of the width of the front end of the convex portion to the width of the opening of the concave portion is preferably 0.99 D / dd .2. In the third flat tube manufacturing metal plate, a convex portion and a concave portion are formed in the wall forming portion, and the length of the convex portion and the concave portion is L1. When the length of the wall forming portion is L, 0.01 SL1 / 1 ^ is satisfied. 1 relationship. Here, the relationship between the length of the convex portion and the concave portion and the length of the wall forming portion is 0.0BL1 / 1 ^ 1. When the friction between the two sides of the convex portion and the two sides of the concave portion is to prevent the convex portion from falling off from the concave portion, such as L 1 / L is less than or equal to 0.01, which reduces the effect of preventing protrusions from falling out from recesses. That is, L 1 / L is a state where the convex portion and the concave portion exist across the entire length of the wall-forming portion. The lower limit of L1 / L is ideally 0.0 5 and the upper limit is ideally 1. 557235 5. Description of the invention (7) In the third flat tube manufacturing metal plate, the convex portion and the concave portion are spaced apart from each other in the length direction of the opposite wall forming portion, and each of them forms a plurality of 'full convex portions and concave portions. When the total length is L 2 and the length of the wall-forming portion is L, a relationship of 0.001 ^ L 2 / L can be satisfied. Here, the relationship between the total length of the full convex portion and the full concave portion and the length of the wall forming portion is 〇1 s L 2 / L. The friction between the two sides of the convex portion and the two sides of the concave portion is required to prevent the convex portion from When the concave portion falls off, if L 2 / L is 0 · 〇1 or less, the effect of preventing the convex portion from falling off from the concave portion is reduced. In addition, since the convex portion and the concave portion are formed at intervals, the upper limit of L2 / L is 1 or less. The lower limit of L2 / L is ideally 0.05, and the upper limit is ideally close to 1. &gt; In the third flat tube manufacturing metal plate, the connecting portion may be formed with a thicker wall than the flat wall forming portion. According to the present invention, the fourth metal plate for flat tube manufacturing is connected to the second metal plate for flat tube manufacturing, and at both sides of the recessed portion of the front end surface of the wall forming portion forming the recessed portion, the convex portion is to be fitted at least on either side. The recessed part is deformed, and a sub-convex part is formed on the side of the crimping protruding part, and the cross-sectional area of the recessed part cut along a plane perpendicular to the longitudinal direction of the wall forming part is A, and the cross-sectional area of the recessed part is also When the total cross-sectional area of the sub-protrusions is E, the relationship of 0.00BE / (A + a) &lt; 0.5 is satisfied. In the case of the fourth flat tube manufacturing metal plate, the metal plate for flat tube manufacturing is bent at the connecting portion to have a thin pin shape, and the wall forming portion and the side wall forming portion are reinforced relative to each other, and the convex portion is embedded in the concave portion. The secondary convex part deforms and pushes the side of the convex part, thereby preventing the convex part from falling off from the concave 557235. V. (8) part of the invention description. Therefore, to resist the force of rejection and keep the metal plate in a bent state, it is not necessary to maintain a bent mold for brazing. As a result, when the condenser is manufactured simultaneously with the manufacture of the flat tube, the temporary fixing body formed by bending the metal plate for flat tube manufacturing and temporarily fixing it becomes easy to handle, and the manufacturing operation of the condenser becomes simple. 0 1 &lt; E / (A + a) &lt; 0.5, in E, in the fourth flat metal tube manufacturing metal plate, the relationship between the cross-sectional area of the convex portion, the cross-sectional area of the concave portion and the total cross-sectional area of the sub-protrusion / (A + a) is less than 0.01, reducing the effect of preventing the convex portion from falling from the concave portion, and when it exceeds 0.5, the contact area of the front end of the wall forming portion of the convex portion and the concave portion is also small, so that the two are joined There is a concern that, for example, a brazed portion may cause poor bonding. That is, the total cross-sectional area of the sub-convex portion refers to the cross-sectional area of the sub-convex portion when the sub-convex portion is formed only on one side of the concave portion, and the sub-convex portion is the two sub-convex portions when formed on both sides of the concave portion. Total cross-sectional area. The relationship between the cross-sectional area of the convex portion, the cross-sectional area of the concave portion, and the total cross-sectional area of the sub-convex portion is ideally 0.05 $ E (A + a) ^ 0.3. In the fourth flat tube manufacturing metal plate, the cross-sectional shape of the sub-convex section cut at a plane perpendicular to the longitudinal direction of the wall forming section may have a first portion continuous to the side surface of the concave portion, and a portion connecting the first portion. The second portion is inclined toward the front end surface side of the wall forming portion in a direction away from the recessed portion. In this case, the secondary convex portion is deformed to further enhance the effect of crimping the convex portion on the side surface. In addition, the front end of the wall forming portion forming the convex portion may form a sub-recessed portion to which the sub-convex portion is fitted. In addition, the connecting portion may have a thicker wall than the flat wall forming portion.

Description of the invention (9) In the fourth flat tube manufacturing metal plate, the convex portion and the concave portion are formed one by one in the wall forming portion, and the length of the convex portion and the length of the concave portion are L1 'wall formation. When the length of the part is L, the relationship of 0. 0 BL 1 / L / s 1 is satisfied. The reason why the length relationship between the length of the convex portion and the concave portion and the wall-forming portion is set to O. OlsLl / Lsl is to prevent the convex portion from being deformed by crimping the side surface of the convex portion by the auxiliary convex portion. When detached from the recessed portion, if L 1 / L is 0 · 0 1 or less, the effect of preventing the detached portion from falling out from the recessed portion is reduced. In addition, the meaning that L1 / L is 1 means that the convex portion and the concave portion exist in the entire length of the cross-wall forming portion. The lower limit of L1 / L is ideally 0.05, and the upper limit is ideally 1. In the fourth flat tube manufacturing metal plate, the convex portion and the concave portion are formed at intervals in the length direction of the wall forming portion, so that the total length of the full convex portion and the full concave portion is L2 and the length of the wall forming portion. When it is L, there is a case where the relationship of 0.00L / L is satisfied. The relationship between the total length of the full convex portion and the full concave portion and the length of the wall forming portion is set to 0.0 1 SL2 / L, because the side is deformed to prevent the convex portion from being deformed on the side surface of the convex portion by the crimping of the sub convex portion. When detaching from the concave portion, when L2 / L is less than or equal to 0 · 01, the effect of preventing the convex portion from falling off from the concave portion is reduced. In addition, since the convex portion and the concave portion are formed at intervals, the upper limit of L 2 / L is 1 or less. The lower limit of L2 / L is ideally 0.05, and the upper limit is ideally close to 1.

Alas, the convex portion (8 5) and the concave portion (8 6) are sometimes formed in the reinforcing wall forming portion (8 3) (8 4) one by one. In this case, the convex portion (8 5) When the length and the length of the recessed portion (86) are L1, and the length of the reinforcing wall forming portion (86) (84) is L, the relationship of 0 · 0 1 s L 1 &lt; 1 is satisfied. In addition, the convex portion (8 5) and the concave portion (8 6) may be formed at plural intervals in the reinforcing wall forming portions (83) (84), respectively. In this case, the full convex portion (85) and the full concave portion are formed. The total length of (86) is L2, and the reinforcing wall forming portion (8 3) (8 5) -31-557235 5. When the length of the invention description (3) is L, the relationship of 0.01SL2 / L is satisfied. The flat tube (70) is manufactured as follows.

Description of the invention (34) In the test pieces of each group, after the two plates were brought into contact with each other at the side and the convex part was embedded in the concave part, it was investigated whether a force was required when the two plates were pulled away. The results are also shown in the effect column of Table 1.尙 In the effect column of Table 1, 0 indicates that a force is required when pulling the two plates in the isolation direction, and X indicates that no equal force is required when pulling the two plates in the isolation direction. From the results shown in Table 1, in order to satisfy the relationship of A &gt; a, A / asl.5, B / bsl.5, C / csl.5, and D / dsl.5 in the examples 1 to 10, they were drawn from the recesses. Force is required when projecting the convex portion. It is suitable for bending the metal plate (80) for flat tube production when the metal plate for flat tube production is bent. The side wall forming portions (81) (82) and the reinforcing wall forming portion (8) 3) (84) is opposed, and when the convex portion (85) is pressed into the concave portion (86), the convex portion (85) is prevented from falling off from the concave portion (86). As a result, it is known that the metal plate (80) is folded. The bent state is temporarily fixed. (Embodiment 8) This embodiment is shown in Figs. 15 (a), (b), and (c). In the flat tube of this embodiment, as shown in FIG. 15 (0), a convex portion (100) formed on the front end surface of each reinforcing wall forming portion (83), and a front end surface formed on the reinforcing wall forming portion (84). The cross-sectional shape of the concave portion (101) cut at a plane perpendicular to the longitudinal direction of the reinforcing wall forming portion (83) (84) is different from the convex portion (85) and concave portion (86) of Embodiment 7 and The recessed portion (101) is formed on both sides of the recessed portion (101) on the front end surface of the reinforcing wall forming portion (84). The recessed portion (100) and the recessed portion (101) are integrally formed to deform and press when the convex portion (100) and the recessed portion (101) are fitted. Except for the sub-convex portions (102) on both sides of the convex portion (100), the structure is the same as that of the flat tube of the embodiment 7 of -36-557235 V. Description of Invention (35). For the production of the flat tube of this embodiment In the case of a metal plate, as shown in FIG. 5A (a), a convex portion (100) formed on the front end surface of each reinforcing wall forming portion (8 3) of the left flat wall forming portion (8 9), and formed on the right side. The recessed portion (101) at the front end surface of each reinforcing wall forming portion (84) of the flat wall forming portion (90) is formed in the longitudinal direction of the reinforcing wall forming portion (83) (84). The cross-sectional shape of the corner plane cut is a square with the same shape, and the cross-sectional areas are equal to each other, which is different from the metal plate for flat tube manufacturing of Embodiment 7. The left flat wall forming portion (90) Both sides of the recessed portion (101) on the front surface of each of the reinforcing wall forming portions (82) are deformed when the convex portion (100) and the recessed portion (101) are to be fitted, and the two sides of the convex portion (100) are pressed. The point of the auxiliary convex portion (102) is different from that of the metal plate for manufacturing a flat tube according to Embodiment 7. The auxiliary convex portion (102) is cut on a plane perpendicular to the longitudinal direction of the reinforcing wall forming portion (84). The cross-sectional shape includes a first portion (102a) continuous to the side of the recessed portion (101), and a reinforcing wall forming portion (84) connected to the front end of the first portion and inclined away from the recessed portion (101). The second portion (102b) on the front end side is the same as that in Embodiment 7. The convex portion (100) and the concave portion (101) are formed when the brazed aluminum sheet is rolled. Although not shown, the There are also the front and two sides of the convex part (100), and the bottom and two sides of the concave part (100). Welding material layer. In addition, the auxiliary convex portion (102) is also formed when the brazing aluminum sheet is rolled. The illustration is omitted, but in the first part (102 a) and the second part (1 0 2 b) There is also a layer of brazing material on the surface. Sub-convex (1 0 2) -37- 557235 V. Description of the invention (36) There is a situation where one reinforcing wall forming portion (84) is formed, and it is separated by A plurality of reinforcing wall forming portions (84) are formed in the longitudinal direction. When the auxiliary convex portion (102) is formed in each of the reinforcing wall forming portions (84), the length is used as the reinforcing wall forming portion (84). The length is less than the length. That is to say, on both sides of the convex portion (100) on the front end surface of the reinforcing wall forming portion (83) forming the convex portion (100), a sub-concave portion embedded in the sub-convex portion (102) may also be formed. Here, the cross-sectional area of the convex portion (100) cut at a plane perpendicular to the longitudinal direction of the reinforcing wall forming portion (83) (the portion attached to the cross section of the chain line in FIG. 15 (a)) is A, and the reinforcing wall The cross-sectional area of the recessed portion (101) cut at a right angle to the plane of the forming portion (84) (the part attached to the cross section of the chain line in Fig. 15 (a)) is a, and the length of the reinforcing wall forming portion (84) When the total area of the two sub-protrusions (102) cut along a plane at right angles (the sum of the cross-sections el and e2 attached to the chain line in Figure 15 (a)) is E, 0.0BE / (A + a) The relationship of ^ 0.5. Alas, the convex portion (100) and the concave portion (101) are sometimes formed one by one on each reinforcing wall forming portion (83) (84). In this case, the length of the convex portion (100) and the When the length of the concave portion (101) is L1, and the length of the reinforcing wall forming portion (8 8 3) (84) is L, the relationship of 0.01sL1 / L <1 is satisfied. Also, the convex portion (100) and the concave portion (101) are sometimes formed in a plural number with a distance from the partition wall forming portion (8 3) (84). In this case, a full convex portion (100) is formed. When the total length of the entire recessed portion (101) is L2, and the length of the reinforcing wall forming portion (83) (84) is L, the relationship of 0.01SL2 / L is satisfied. -38- 557235 5. Description of the invention (37) In the flat tube manufacturing method of this embodiment, a metal plate (80) for flat tube manufacturing is bent into a thin pin shape at a connecting portion (88) by a roll forming method. The side wall forming portions (8 1) (82) and the reinforcing wall forming portions (8 3) (84) are opposed to each other, and when the convex portion (100) and the concave portion (101) are fitted at the same time, the auxiliary convex portion (102) ) Deformation is pushed from both sides of the convex part (100), and accordingly, the convex part (85) is prevented from falling off from the concave part (86), except that the metal plate for flat tube manufacturing is temporarily fixed in a bent state. Except for the point (refer to FIG. 15 (b)), it is the same as the manufacturing method of the flat tube of the seventh embodiment. That is, when the convex portion (100) is embedded in the concave portion (101), it is the result of the deformation of the convex portion (100) and the concave portion caused by the deformation of the sub convex portion (102). 〇) There is a slight gap (103) between the front end surface and the bottom surface of the recess (101). This gap (103) is the same as the flat tube manufacturing method of the seventh embodiment, and is buried in the brazing material (104). In the same manner as in the flat tube manufacturing method of the seventh embodiment, during the brazing, when the pressing force applied by the two flat wall forming portions (8, 9) and (90) toward each other is applied, according to the fitting convex portion (100 ) And the recessed portion (101), to prevent the positional displacement of the side wall forming portion (81) (82) and the reinforcing wall forming portion (83) (84) in the thickness direction, that is, the flat wall forming portion (89) ( 90) wide direction. Therefore, when this brazing is performed, the side wall forming portions (81) (82) and the reinforcing wall forming portions (83) (84) are surely brazed across the entire length, and the pressure resistance of the obtained flat pipe is apparent. Become superior. When the flat tube of this embodiment is used as, for example, the refrigerant flow tube (1 1 2) of the condenser shown in Fig. 16, the production of the flat tube system may be performed concurrently with the production of the condenser -39- 557235. 5. Description of the invention (38) . In other words, the condenser is manufactured in the same manner as in the seventh embodiment except that it is a metal plate for manufacturing a flat tube in a bent state, except that it is temporarily fixed as described above. In the eighth embodiment, the shape or size relationship of the convex portions and the concave portions may be the same as that of the seventh embodiment. Next, a specific example of the eighth embodiment will be described together with a comparative example.

For a 4 mm plate, a convex portion extending in the lengthwise direction is formed across the entire length of the central portion of the side surface of the plate on one side, and a wide center portion of the lateral surface of the plate on the other side extends across the entire length. Recess in the longitudinal direction. Further, a sub-convex portion is formed on at least one side of both sides of the concave portion of the side surface of the plate on which the concave portion is formed. Shapes cut at a plane where the convex and concave portions are at right angles to the longitudinal direction of the plate, and shapes cut at a plane where the sub-convex portions are at right angles to the longitudinal direction of the plate are shown in Figure 15 (a), respectively. . In addition, a plate having convex portions, a concave portion, and a plate having sub convex portions were prepared in two groups of eight test pieces. The coefficient of friction of the 尙 ′ plate surface is 0.3. The sum of the cross-sectional area of the convex section cut at a plane perpendicular to the plate length direction of the test piece of each group and the cross-sectional area of the concave section of the plane cut plane at right angle to the plate length direction (A + a) , The number of sub-protrusions, the width F of the sub-protrusions (refer to Figure 15 (a)), the height G of the sub-protrusions (refer to j 5 -40-557235) V. Description of the invention (39) Figure (a )), The total cross-sectional area E (= el + e2) of the sub-convex section cut at a plane perpendicular to the length direction of the plate (refer to Figure 15 (a)) and El (A + a) are shown in Table 2 respectively. Shown. That is, when the number of sub-protrusions is one, it is a state where sub-protrusions are formed on one side of the recess, and the cross-sectional area of one sub-protrusion is the total cross-sectional area. When the number of sub-protrusions is two, the sub-protrusions are formed on both sides of the recess. Table 2 -41- 557235 V. Description of the invention (40) Table 2
