     SUMMARY OF INVENTION 
     Technical Problem 
     However, in the belt molding obtained by the technique of the above Patent Document 1, the same fibers are flocked in an upper seal lip and a lower seal lip of the belt molding. For this reason, it is not possible to cope with a case where different levels of performance are required in the upper seal lip and the lower seal lip. 
     For example, although longer fibers of the upper seal lip easily prevent entering of foreign matter, such as sand, if fibers of such a length that entering of the foreign matter is easily prevented are also flocked in the lower seal lip, the distance from the window pane becomes long and also the gap between the fibers increases. Therefore, there is a fear that the effect of noise insulation may deteriorate. 
     Accordingly, a problem to be solved by the invention is to provide a belt molding that has abutment portions having fibers, which are suitable for the respective sealing portions, being erected therefrom. 
     Solution to Problem 
     (1) In order to solve the above-described problem, the present invention provides a belt molding attached to a vehicle door and abutting against a window pane which is arranged in a window opening of a door body and can be moved up and down, the belt molding including: an elongated body portion attached along a flange of the window opening; and two or more sealing portions protruding from portions of the body portion facing the window pane and respectively having abutment portions which are formed along a longitudinal direction of the body portion and abut against the window pane, wherein numerous fibers are erected from a surface of the abutment portion of each of the sealing portions, and wherein the fibers of one abutment portion are different from the fibers of another abutment portion. 
     In this configuration, since the fibers erected from the respective sealing portions are different from each other, the respective sealing portions show different behaviors when the sealing portions abut against the window pane. For this reason, abutment portions suitable for the respective sealing portions can be obtained depending on positions where the respective sealing portions are formed. 
     (2) In the belt molding according to the above-described (1), a sheet material having a fiber layer, in which the numerous fibers are erected from a surface of a sheet-like base material, may be adhered to at least one of the abutment portions. According to this configuration, an abutment portion having a high-density fiber layer that is relatively small in dispersion can be obtained. 
     (3) In the belt molding according to the above-described (2), the sheet materials having fiber layers in which different fibers are erected may be respectively adhered to two or more of the abutment portions. According to this configuration, two or more abutment portions having high-density fiber layers that are relatively small in dispersion can be obtained. 
     (4) In the belt molding according to any one of the above-described (1) to (3), the fibers of the one abutment portion may be shorter than the fibers of the other abutment portion. According to this configuration, the distance between the sealing portion from which short fibers are erected and the window pane becomes short. As a result, excellent sound insulating properties can be given to the sealing portion. Additionally, even when a vehicle is used at a low temperature, such as in winter, waterdrops do not easily accumulate between the window pane and the sealing portion. As a result, sticking of the sealing portion onto the window pane caused by freezing of the waterdrops can be prevented. 
     (5) In the belt molding according to any one of the above-described (1) to (3), the fibers of the one abutment portion may be longer than the fibers of the other abutment portion. According to this configuration, in the sealing portion from which long fibers are erected, the fiber layer of the abutment portion plays the role of a cushion even against relatively large foreign matter, such as sand, and the force of pressing the foreign matter against a surface of the window pane is relaxed. Therefore, damage (biting) to the window pane caused by the foreign matter can be prevented. 
     (6) In the belt molding according to the above-described (4) or (5), the fibers of the abutment portion of the sealing portion arranged on an upper side may be longer than the fibers of the abutment portion of the sealing portion arranged on a lower side. According to this configuration, damage to the window pane caused by foreign matter can be prevented by the upper sealing portion of which the fibers are long, and excellent sound insulating properties can be secured by the lower sealing portion of which the fibers are short. 
     (7) In the belt molding according to any one of the above-described (1) to (6), the fiber length of at least one of the abutment portions may be 0.3 mm or greater and 1.0 mm or smaller. According to this configuration, fiber layers suitable for the abutment portions of the belt molding can be formed. 
     (8) In the belt molding according to any one of the above-described (1) to (7), the fibers of the one abutment portion may be thinner than the fibers of the other abutment portion. According to this configuration, the fibers are easily bent and the distance between the abutment portions and the window pane becomes short. Therefore, excellent sound insulating properties can be given to the sealing portions. 
     (9) In the belt molding according to any one of the above-described (1) to (7), the fibers of the one abutment portion may be thicker than the fibers of the other abutment portion. According to this configuration, the state of abutment with the window pane is not easily influenced by the presence/absence of waterdrops. Therefore, even if the window pane is moved up and down in a state where water has adhered to the abutment portions, abnormal noise is not easily generated. 
     (10) In the belt molding according to the above-described (8) or (9), the fibers of the abutment portion of the sealing portion arranged on a lower side may be thinner than the fibers of the abutment portion of the sealing portion arranged on an upper side. According to this configuration, excellent sound insulating properties can be given to the lower sealing portion. 
     (11) In the belt molding according to any one of the above-described (1) to (10), the fiber thickness of at least one of the abutment portions may be 1.0 decitex or greater and 4.5 decitex or smaller. According to this configuration, fiber layers suitable for the abutment portions of the belt molding can be formed. 
     (12) In the belt molding according to any one of the above-described (1) to (11), the fibers of at least one of the abutment portions may be made of nylon-based resin. According to this configuration, the abutment portion can be cheaply formed compared to other types of fibers. 
     (13) In the belt molding according to any one of the above-described (1) to (12), the fibers of at least one of the abutment portions may be made of polyester-based resin. According to this configuration, even in a state where water has adhered to the abutment portion, generation of abnormal noise when the window pane is moved up and down can be suppressed. 
     (14) In the belt molding according to the above-described (12) or (13), the fibers of the abutment portion of the sealing portion arranged on an upper side may be made of polyester-based resin, and the fibers of the abutment portion of the sealing portion arranged on a lower side may be made of nylon-based resin. According to this configuration, abnormal noise when the window pane is moved up and down can be suppressed at the upper sealing portion to which water adheres easily, and an inexpensive belt molding can be obtained. 
     (15) In the belt molding according to any one of the above-described (1) to (14), the belt molding may be an inner belt molding attached to a vehicle interior side. 
     (16) In the belt molding according to any one of the above-described (1) to (14), the belt molding may be an outer belt molding attached to a vehicle exterior side. 
     Advantageous Effects of Invention 
     According to the invention, a belt molding having abutment portions suitable for the respective sealing portions can be provided. 
    
    
     
       BRIEF DESCRIPTION OF DRAWINGS 
         FIG. 1  is a side view of a vehicle door illustrating an attachment position of a belt molding in an embodiment of the invention. 
         FIG. 2  is a cross-sectional view taken along II-II of  FIG. 1 . 
     
    
    
     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, an embodiment, in which a mode for carrying out the invention is applied to a belt molding (also referred to as a belt molding, a weather strip, a water wiping seal, or the like) mounted along a window opening of a vehicle and is specified, will be described. 
     First, a schematic configuration of a belt molding attached to a vehicle door  1  will be described with reference to  FIGS. 1 and 2 . 
     As illustrated in  FIG. 1 , an outer belt molding  10  that is an example of the belt molding is attached along a front-rear direction of a vehicle on a lower side of a peripheral edge of a window opening  3  of the vehicle door  1 . 
     Further, as illustrated in  FIG. 2 , as the belt molding, there are the outer belt molding  10  (an example of the belt molding) arranged on an exterior side of a window pane, and an inner belt molding  100  (an example of the belt molding) arranged on an interior side of the window pane  5 . In addition, the inner belt molding  100  that is an example of the belt molding is attached along the front-rear direction of the vehicle on the lower side of the peripheral edge of the opening  3  on the interior side of the window pane  5 . A door panel  4  has an outer door panel  11  and an inner door panel  110 . The outer belt molding  10  is attached to the outer door panel  11 , and the inner belt molding  100  is attached to the inner door panel  110 . The window pane  5  is arranged between the outer belt molding  10  and the inner belt molding  100 , and the window pane  5  is moved up and down in an upper-lower direction by an actuator, such as a motor (not illustrated). 
     The outer belt molding  10  abuts against the surface of the window pane  5  of the exterior side so as to perform sealing, and the inner belt molding  100  abuts against the surface of the window pane  5  on the interior side so as to perform sealing. The outer belt molding  10  and the inner belt molding  100  have a role in wiping off waterdrops or foreign matter (sand, grit, dust, or the like) adhering to the surfaces of the window pane when the window pane moves up and down, so as to keep an occupant&#39;s lateral view excellent. 
     In addition, in the present embodiment, when each belt molding is attached to the vehicle door  1 , a side directed to the vehicle exterior side is referred to as an exterior side, and a side directed to the vehicle interior side is referred to as an interior side. Additionally, when each belt molding is attached to the vehicle door  1 , a side that becomes the upper side in the gravitational direction is referred to as an upper side, and a side that becomes the lower side in the gravitational direction is referred to as a lower side. Additionally, a longitudinal direction refers to the longitudinal direction of each belt molding, and a width direction refers to a direction orthogonal to the longitudinal direction. 
       FIG. 1  is a view when the vehicle door is seen from the exterior side, and the outer belt molding  10  is illustrated as the belt molding. Hereinafter, the outer belt molding  10  will be described in detail. 
     As illustrated in  FIG. 2 , the outer belt molding  10  has an elongated body portion  15  having a substantially U-shaped cross section, and a plurality of (two in the present embodiment) sealing portions  16  and  16   a . The body portion  15  has an exterior lateral wall portion  12  and an interior lateral wall portion  13  that are arranged in parallel in an interior and exterior direction at a predetermined distance from each other, and a connecting portion  14  that connects upper portions of the exterior and interior lateral wall portions. A surface of the interior lateral wall portion  13  of the body portion  15 , which faces the window pane  5  in a state where the belt molding is attached to the vehicle door  1 , is provided with the plurality of (two in the present embodiment) sealing portions  16  and  16   a  that protrude toward the window pane  5  from the surface. 
     In the present embodiment, a tip of the outer door panel  11  forms a flange portion  18  by being subjected to hemming processing in a state where the tip is folded so as to wrap a tip of a reinforcement  17 . The outer belt molding  10  is attached to the flange portion  18  by inserting the flange portion  18  into the body portion  15 . Further, the outer belt molding  10  is retained on the flange portion  18  by an engaging portion  19  that is formed at a lower end of the interior lateral wall portion  13  and is engaged with the folded tip of the flange portion  18 , a retaining lip  20  that protrudes from the exterior lateral wall portion  12  and abuts against the flange portion  18 , and a cover lip  21  that protrudes from a lower end of the exterior lateral wall portion  12  and abuts against the outer door panel  11 . 
     Further, in the present embodiment, the two sealing portions  16  and  16   a  respectively protrude from an upper end and the lower end of the interior lateral wall portion  13  toward the window pane  5 . Seal body portions  22  and  22   a  form a lip shape. Additionally, seal root portions  23  and  23   a  have portions that are formed so as to be thinner than the seal body portions  22  and  22   a , and are deformed at the thinned portions according to the up and down of the window pane  5 . Moreover, surfaces of the seal body portions  22  and  22   a  that face the window pane  5  are formed with abutment portions  24  and  24   a  that abut against the window pane  5 , and the abutment portions  24  and  24   a  have fiber layers  25  and  25   a  for reducing the sliding resistance between the window pane  5  and the sealing portions  16  and  16   a , on the surfaces thereof on the window pane. The fiber layers  25  and  25   a  are formed by numerous fibers (piles) being erected so as protrude substantially perpendicularly from the respective surfaces of the abutment portions  24  and  24   a.    
     Further, the inner belt molding  100  also has a structure similar to the outer belt molding  10 . That is, the inner belt molding  100  has a body portion  150  having a exterior lateral wall portion  120 , a interior lateral wall portion  130 , and a connecting portion  140 , and a plurality of (two in the present embodiment) sealing portions  160  and  160   a  that protrude from the exterior lateral wall portion  120  toward the window pane. When the body portion  150  is attached to a flange portion  180  of the inner door panel  110 , a locking portion  190  is engaged with a lanced portion of the flange portion  180 , and retaining lips  200  and  200   a  and a cover lip  210  comes into contact with the surface of the inner door panel  110 . Also, the sealing portions  160  and  160   a  of the inner belt molding  100  are also formed with seal root portions  230  and  230   a  having portions that can be more easily deformed than the seal body portions  220  and  220   a , and abutment portions  240  and  240   a  that abut against the window pane  5 . The abutment portions  240  and  240   a  are respectively formed with fiber layers  250  and  250   a  configured by numerous fibers. 
     In addition, an interior material, such as a door trim (not illustrated), is arranged on the interior side of the inner belt molding  100  in the present embodiment. 
     Further, the body portions  15  and  150  of the respective belt moldings are respectively made of materials that are moldable by extrusion molding, injection molding, or the like. For example, thermoplastic elastomers, resin, rubber, or the like can be used, and specifically, an olefin-based thermoplastic elastomer (TPO), a styrene-based elastomer (TPS), polyvinyl chloride resin (PVC), polypropylene resin (PP), an ethylene propylene diene copolymer (EPDM), and the like are included as the materials. 
     As the materials that form the respective body portions  15  and  150 , materials of which the durometer hardness (Type D) according to JISK7215 is HDD 50 to 80 are preferably used. In the present embodiment, the body portions are formed of a TPO material of HDD 65. 
     The sealing portions  16 ,  16   a ,  160 , and  160   a  of the respective belt moldings are made of materials that are moldable by extrusion molding, injection molding, or the like, are softer than the body portions, and are elastically deformable. For example, thermoplastic elastomers, resin, rubber, or the like can be used, and specifically, an olefin-based thermoplastic elastomer (TPO), a styrene-based elastomer (TPS), polyvinyl chloride resin (PVC), polypropylene resin (PP), an ethylene propylene diene copolymer (EPDM), and the like are included as the materials. 
     Further, as the materials that form the respective sealing portions  16 ,  16   a ,  160 , and  160   a , materials of which the durometer hardness (Type A) according to JISK7215 is HDA 50 to 80 are preferably used. In the present embodiment, the sealing portions are formed of a TPO material of HDA 70. 
     Here, portions which abut against the flange portions  18  and  180  and the interior material, such as the retaining lips  20 ,  200 , and  200   a  and the cover lips  21  and  210  of the body portions  15  and  150 , are also formed of the same materials as the sealing portions  16 ,  16   a ,  160 , and  160   a.    
     Moreover, core members made of metal or hard resin may be buried in the body portions  15  and  150  of the respective belt moldings in order to secure retaining forces when the belt molding is attached to the flange portions  18  and  180 . In this case, the body portions can be formed by covering the surroundings of the core members with elastically deformable materials that have the same level of hardness as the sealing portions. 
     As for the respective belt moldings, first, the body portions  15  and  150  and the sealing portions  16 ,  16   a    160 , and  160   a  are integrally molded through co-press molding, and the fiber layers of the abutment portions are molded simultaneously with extrusion molding or after extrusion molding. Then, processing for attaching the belt molding  2  to the vehicle door  1 , such as press processing of terminals or mounting of accessories such as clips, is performed. 
     Additionally, the respective sealing portions of each of the outer belt molding  10  and the inner belt molding  100  are at least two and are arranged substantially in parallel in the upper-lower direction along the body portion. Also, the upper sealing portions  16  and  160  are provided with the abutment portions  24  and  240  and the fiber layers  25  and  250  that abut against the window pane  5 . Also, the lower sealing portions  16   a  and  160   a  are provided with the abutment portions  24   a  and  240   a  and the fiber layers  25   a  and  250   a  that abut against the window pane  5 . 
     These fiber layers can be formed by an arbitrary method, such as electrostatic flocking, spraying of fibers, or sticking of a strip sheet material in which fibers are erected from a base material in advance. 
     Additionally, a plurality of these methods can be used. For example, a sheet material in which fibers are erected can be stuck on the upper sealing portions  16  and  160  so as to form the fiber layers  25  and  250 , and the fiber layers  25   a  and  250   a  can also be formed on the lower sealing portions  16   a  and  160   a  by electrostatic flocking. 
     Moreover, the fiber layers are typically formed by performing bonding in a state where an adhesive is applied on a molded product or a base material of a sheet material, and fibers are erected on the molded product or the base material by charging of static electricity, or the like. Fibers that are upright with respect to the surface of a body to be bonded are present and fibers that are adhered obliquely with respect to the surface are also present. 
     Here, generally, the fiber layers of the sheet material have less dispersion and are more uniform, are more densely erected, and have a higher density than the fiber layers directly formed on a molded product by the so-called electrostatic flocking. 
     Additionally, when the sheet material in which fibers are erected is bonded on an extrusion-molded product simultaneously with the extrusion molding of the body portion, it is preferable to use the sheet material having a base material formed of a material of the same kind as or a material having an excellent miscibility with the molded product because the sheet material can be easily adhered to the molded product. For example, when a molded product is formed of TPO, if a sheet material formed of olefin-based resin is used as the base material, the sheet material can be thermally welded to the molded product by the heat generated when the molded product is molded. Additionally, a sheet material and a molded product can also be bonded by applying an adhesive, and thermal welding and application of an adhesive can also be used together. 
     Here, the length of the fibers that form the fiber layers is 0.3 mm or greater and 1.0 mm or smaller, and preferably 0.5 mm and 0.8 mm are used. 
     If the length of the fibers is shorter than 0.3 mm, the fibers are easily buried in an adhesive layer. As a result, when the abutment portions come into contact with the window pane, there is a fear that the fiber layers may not come into contact with the window pane but the adhesive layer may come into contact with the window pane, and abnormal noise may be generated when the window pane is moved up and down. Additionally, if the length of the fibers is greater than 1.0 mm, there is a fear that the distance between the fiber layers and the window pane may become too long and sound insulating properties may deteriorate. 
     Additionally, the thickness of the fiber is 1.0 decitex (also referred to as dtex) or greater and 4.5 decitex or smaller, and preferably 1.7 decitex and 3.3 decitex are used. 
     If the fibers are thinner than 1.0 decitex, there is a fear that the durability particularly when the fibers are used for a long period of time is not enough. Additionally, if the fibers are thicker than 4.5 decitex, there is a fear that the area of contact with the window pane may become too large, and sliding resistance may be increased or the rubbing noise with the window pane may be generated. 
     Here, as the materials of the fibers, other than nylon-based resin and polyester-based resin, polypropylene-based resin, acrylic resin, aramid-based resin, fluorine-based resin, and the like can also be used. 
     Here, the “decitex” is a unit based on JISL0101 and L0104, means weight per unit length, and is generally used as a unit that indirectly expresses the thickness of the fibers. Further, the fiber layers  25 ,  25   a ,  250 , and  250   a  in  FIG. 2  are schematically emphasized and illustrated than they actually are, and the thickness of actual fiber layers does not necessarily coincide with that illustrated in  FIG. 2 . 
     In the present embodiment, in the upper sealing portion  16  of the outer belt molding  10 , for example, fibers, which are made of nylon-based resin, are 0.8 mm in length, and are 3.3 decitex in thickness, form the fiber layer  25 . Further, in the lower sealing portion  16   a , for example, fibers, which are made of the polyester-based resin, are 0.5 mm in length, and are 1.7 decitex in thickness, form the fiber layer  25   a.    
     Additionally, in the upper sealing portion  160  of the inner belt molding  100 , for example, fibers, which are made of nylon-based resin, are 0.8 mm in length, and are 3.3 decitex in thickness, form the fiber layer  250 . Further, in the lower sealing portion  160   a , for example, fibers, which are made of the polyester-based resin, are 0.5 mm in length, and are 1.7 decitex in thickness, form the fiber layer  250   a.    
     In the respective belt moldings  10  and  100 , the fiber layers  25  and  250  of the upper sealing portions  16  and  160  are made of the fibers longer than the fibers that form the fiber layers  25   a  and  250   a  of the lower sealing portions  16   a  and  160   a . For this reason, foreign matter is easily taken into the roots of the fiber layers and entering of the foreign matter is easily prevented. Additionally, since the fiber layers  25  and  250  play the role of a cushion even when foreign matter enters between the window pane  5  and the abutment portions  24  and  240 , the foreign matter is not strongly pressed against the window pane  5 , and damage to the window pane  5  particularly in the outer belt molding  10  can be suppressed. 
     Additionally, when the fiber length and the fiber thickness are the same, since the fibers made of the nylon-based resin are more easily deformed than the fibers made of the polyester-based resin, the effect of suppressing the damage to the window pane  5  is relatively high, which is preferable. 
     Additionally, in the inner belt molding  100  of the present embodiment, the fiber layer  250   a  of the lower sealing portion  160   a  are made of the fibers shorter than the fibers that form the fiber layer  250  of the upper sealing portion  160 . For this reason, the distance between the abutment portion  240   a  and the window pane  5  is short, and the sound insulating properties are excellent. When the short fibers are formed on the sealing portion in the inner belt molding  100  particularly as in the present embodiment, there is an effect that the noise, which is going to pass through the inside of the door to propagate within the vehicle, can be shielded. 
     Additionally, when the fiber layers  25   a  and  250   a  of the lower sealing portions  16   a  and  160   a  are made of the short fibers in the respective belt moldings  10  and  100 , the amount of waterdrops that enter between the window pane  5  and the sealing portions and accumulate is small. Therefore, there is an advantage that, even if the waterdrops adhere to the window pane, the waterdrops easily gets dry, and sticking of the sealing portions  16   a  and  160   a  caused by freezing during a cold time can also be prevented. 
     Here, when the fiber layer  250  of the upper sealing portion  160  of the inner belt molding  100  is formed of the short fibers similar to the fiber layer  250   a  of the lower sealing portion  160   a , this is more preferable from the viewpoint of an improvement in sound insulating properties or sticking prevention. 
     Moreover, since the waterdrops more easily get dry in the fiber layers formed of the fibers made of the polyester-based resin than the fibers made of the nylon-based resin when the fiber lengths are the same, sticking of the sealing portions onto the window pane can be easily prevented, which is preferable. 
     Additionally, in the respective belt moldings  10  and  100 , the fiber layers  25   a  and  250   a  of the lower sealing portions  16   a  and  160   a  are formed of the fibers of the polyester-based resin. When the fiber layers are formed of the fibers of the polyester-based resin, even when the window pane  5  moves up and down in a state where waterdrops have adhered to the abutment portions  24   a  and  240   a , sliding noise is not easily generated. Additionally, since sliding abnormal noise is not easily generated if the fiber layers are formed of the fibers of the polyester-based resin, the fiber layers can be strongly made to abut against the window pane  5 , and waterdrops, dust, or the like adhering to the window pane  5  can be excellently wiped off. 
     Here, the sliding abnormal noise means a sound that is generated as the sealing portions of the belt molding and the surfaces of the window pane are rubbed against each other when the window pane  5  is closed or when the window pane begins to open. When the window pane and the sealing portions strongly contact each other or when waterdrops have adhered between the window pane and the sealing portions, the sliding abnormal noise is easily generated. 
     For this reason, from the viewpoint of preventing the abnormal noise when waterdrops have adhered, the fiber layer  25  of the upper sealing portion  16  of the outer belt molding  10  and the fiber layer  250  of the upper sealing portion  160  of the inner belt molding  100  may be formed of the fibers made of the polyester-based resin in which the waterdrops easily get dry. 
     Further, from the viewpoint of suppressing damage to the window pane, the fiber layer  25   a  of the lower sealing portion  16   a  of the outer belt molding  10  and the fiber layer  250   a  of the lower sealing portion  160   a  of the inner belt molding  100  may be formed of the fibers made of the nylon-based resin that is easily deformed. 
     Moreover, as the density per unit area of the fibers that form the fiber layers is higher, the sound insulating properties or the properties of wiping-off the waterdrops adhering to the window pane surface are excellent. 
     Although the embodiment related to the invention has been described above, the invention is not limited thereto and can be appropriately modified without departing from the spirit of the invention. 
     For example, the fiber layer  25  of the upper sealing portion  16  and the fiber layer  25  of the lower sealing portion  16   a  in the above embodiment may be set so as to be inverted upside down or inverted vehicle inside out. For example, in the inner belt molding  100 , a fiber layer made of fibers that are made short and thin (for example, 0.5 mm, 1.7 decitex) may be formed on the upper sealing portion  160 , and a fiber layer that is made long and thick (0.8 mm, 3.3 decitex) may be formed on the lower sealing portion  160   a . Further, fiber layers respectively made of the same fiber (for example, 0.5 mm, 1.7 decitex, polyester-based resin) may be formed on the upper sealing portion  160  and the lower sealing portion  160   a  of the inner belt molding  100 . 
     Additionally, the upper sealing portion  16  and the lower sealing portion  16   a  of the outer belt molding  10 , and the upper sealing portion  160  and the lower sealing portion  160   a  of the inner belt molding  100  may have the fiber layers  25 ,  25   a ,  250 , and  250   a  respectively made of different fibers. Moreover, three or more sealing portions may be formed on one belt molding, or two or more fiber layers may be formed on one sealing portion. 
     The fiber layers of any abutment portions may be respectively formed of fibers having the same length and different thicknesses, fibers having the same thickness and different lengths, or fibers having the same length and the same thickness but different materials. Additionally, the shape of the sealing portions  16  and  160  is not limited to the lip shape. For example, the shape of the sealing portions may be a ridge having a substantially semicircular cross-section. 
     The invention is not limited to the sealing portions  16  and  160  of the belt molding  2  that is mounted along the lower side of the opening of the vehicle door  1 . For example, the invention can be applied to and carried out in arbitrary portions, such as stabilizers, which slide on the window pane integrally or separately from the belt moldings. 
     Additionally, in the above embodiment, the body portion and the sealing portions are integrally molded by co-extrusion molding. However, the invention is not necessarily limited to this process of manufacture. For example, while the body portion is formed in a predetermined shape by injection molding, the fiber layers are formed on the abutment portions of the sealing portions simultaneously when or after the sealing portions are formed by extrusion molding. Then, the sealing portions may be cut in a predetermined length, and may be adhered to the body portion by heat caulking, welding, bonding, or the like. 
     The present application is based on Japanese Patent Application No. 2012-234180 filed on Oct. 4, 2012, the content of which is incorporated herein by reference.
