In the width direction, the length of the soft first covering portion 41F is longer than the length of the hard first covering portion 42F. Therefore, as shown in FIGS. 2 and 4, the distal end portion of the soft first covering portion 41 </ b> F comes into contact with the guide rail 505 (moving body) of the article holding device 503. On the other hand, the distal end portion of the hard first covering portion 42F is not in contact with the guide rail 505 (moving body) of the article holding device 503. A downward engaging portion 35F is formed on the lower surface of the base portion 3F.

The length of the soft first covering portion 41S is longer than the length of the hard first covering portion 42S. Therefore, as shown in FIG. 5, the distal end portion of the soft first covering portion 41 </ b> S contacts the guide rail 512 (moving body) of the first seating seat 510. On the other hand, the tip of the hard first covering portion 42S is not in contact with the guide rail 512 (moving body) of the first seating sheet 510. A downward engaging portion 35S is formed on the lower surface of the base portion 3S.

  In addition, according to the present Example, the base 3 has the material, structure, and function corresponding to the base 3F and the base 3S. The soft first covering portion 41 has a material, a structure, and a function corresponding to the soft first covering portion 41F and the soft first covering portion 41S. The hard first covering portion 42 has a material, a structure, and a function corresponding to the hard first covering portion 42F and the hard first covering portion 42S.

  A process for manufacturing the molding 2 of the present embodiment will be described. First, the molding material 2K (see FIG. 6) having a main cross-sectional shape 20 is formed by extruding the raw material in one direction by a forming process. FIG. 6 shows a plane of the molding material 2K. As shown in FIG. 6, the main cross-sectional shape 20 extends in the length direction over the entire length of the molding material 2 </ b> K. In the molding material 2K, the soft first covering portion 41, the hard first covering portion 42, the soft second covering portion 51, and the hard second covering portion 52 are continuous in the length direction of the molding material 2K. Two grooves 7 extending in the length direction of the molding material 2K are formed on the upper surface of the molding material 2K.

  Next, a cutting process is performed. In the cutting step, as shown in FIG. 6, a cutting process (shearing) is performed by a blade body along a first cutting line 71 extending along the groove 7 and a second cutting line 72 extending in a direction intersecting the groove 7. Process). Thus, a first cutout region 711 corresponding to the first non-polymerization region W1 side is formed on one end side in the length direction of the molding material 2K. Similarly, a second cutout region 712 corresponding to the second non-polymerization region W2 side is formed on the other end side in the length direction of the molding material 2K. As a result, the molding 2 (see FIG. 2) according to the present embodiment is formed.

  As described above, when the blade is applied to the molding material 2K, depending on the conditions, the cut portion of the molding material 2K may be whitened. In this case, there is a possibility that the appearance may deteriorate due to whitening. In this respect, according to the present embodiment, the groove portion 7 is formed in the molding material 2K, and the blade body is applied to the groove bottom surface 74 of the groove portion 7 to be cut. For this reason, even if whitening (modified portion) occurs, whitening occurs in the vicinity of the groove bottom surface 74. Here, whitening is less noticeable due to the groove depth h of the groove 7 (see FIGS. 4 and 5). Further, as shown in FIGS. 4 and 5, a skin member 8 that forms a floor surface of the passenger compartment is applied to the molding 2. In this case, the whitened portion of the molding 2 is near the boundary between the molding 2 and the skin member 8. For this reason, an effect of making the whitened portion more difficult to notice is obtained.

  Further, since the groove 7 after the cutting process forms an appropriate concave space, there is a steep step where the end face of the molding 2 suddenly rises in the vicinity of the boundary MA (see FIGS. 4 and 5) between the molding 2 and the skin member 8. This eliminates the effect of reducing the effect of the steep step. The cutting may be performed with a high energy beam such as a laser beam instead of the blade. In this case as well, even if the beam irradiation trace remains, the beam irradiation trace becomes inconspicuous due to the concave space of the groove portion 7.

  As described above, according to the present embodiment, the long rail portion 100 includes the overlapping region WO in which the first rail portion 101 and the second rail portion 102 overlap in the length direction, the first non-overlapping region W1, and the first rail portion. 2 has a non-polymerized region W2. The molding 2 according to the present embodiment has a main cross-sectional shape 20 corresponding to the polymerization region WO, a first sub-cross-sectional shape 21 corresponding to the first non-polymerization region W1, and a first non-polymerization region W2. 2 sub-cross-sectional shapes 22. That is, the molding 2 according to the present embodiment has three cross-sectional shapes. For this reason, even if there is a single molding 2 in this embodiment, it is possible to deal with the three regions of the long rail portion 100: the overlapping region WO, the first non-polymerized region W1, and the second non-polymerized region W2. Therefore, three types of moldings are not required, such as the molding for the overlapping region WO of the long rail portion 100, the molding for the first non-polymerizing region W1, and the molding 2 for the second non-polymerizing region W2. Therefore, the number of parts can be reduced.

  Further, additional features of this embodiment will be described.

  As shown in FIG. 4, a contact surface 42 r is formed on the back surface of the hard first covering portion 42. The contact surface 42r has a circular arc shape in cross section, and is in contact with or capable of contact with the peripheral edge (receiving surface 90) of the first opening 111 of the long rail portion 100. The circular arc surface of the receiving surface 90 And a shape that substantially matches. For this reason, when an external force acts downward (in the direction of the arrow DA shown in FIG. 4) on the hard first covering portion 42, such as when a foreign object or the like tries to enter the opening, the contact of the hard first covering portion 42 The contact surface 42r is received by the receiving surface 90 of the long rail portion 100. Thereby, the excessive deformation of the hard first covering portion 42 is suppressed, and the protection of the hard first covering portion 42 can be improved. Similar effects can be obtained with respect to the contact surface 52r of the hard second covering portion 52.

  The soft first covering portion 41 is formed using a soft polymer material (resin material or rubber material) that is more flexible than the hard first covering portion 42 as a base material. As shown in FIG. 4, the soft first covering portion 41 includes a neck portion 41 a that is thinner than the average thickness of the base portion 3 and a head portion 41 c that is thicker than the neck portion 41 a. The amount of elastic deformation of the soft first covering portion 41 is increased by the neck portion 41a. The soft first covering portion 41 is formed so as to be slightly upward from the horizontal as it goes to the tip thereof. This is more advantageous for suppressing the entry of foreign matter into the opening 111. In addition, the soft 2nd coating | coated part 51 has the neck part 51a and the head 51c similarly, and the effect similar to the above-mentioned is obtained.

  -The soft 1st coating | coated part 41 is formed with the soft material as mentioned above, and has high elastic deformation property. For this reason, when a moving body such as a guide rail moves along the long rail portion 100 during the movement of the seat, the sliding resistance is reduced. Therefore, it is advantageous for moving a moving body such as a guide rail along the long rail portion 100 while the soft soft first covering portion 41 covers the first opening 111. In addition, the same operation effect is acquired also about the soft 2nd coating | coated part 51. FIG.

  -As shown in FIG. 4, the boundary surface 33 of the soft 1st coating | coated part 41 and the base 3 is made into the inclined surface. As a result, since the area of the boundary surface 33 increases, the integral joining property of the soft first covering portion 41 and the base portion 3 is improved. As shown in FIG. 4, the boundary surface 33 is an inclined surface that descends toward the tip of the head portion 41 c of the soft first covering portion 41. In this case, when the soft first covering portion 41 is deformed downward (in the direction of arrow DA shown in FIG. 4) due to the influence of foreign matter or the like, the soft first covering portion 41 is compared with the case where the inclination direction of the boundary surface 33 is reverse. It is suppressed that the peeling force which peels the coating | coated part 41 from the base 3 acts on the interface 33. FIG. Therefore, the bondability between the soft first covering portion 41 and the base portion 3 is ensured. Similar effects can be obtained for the soft second covering portion 51.

  As shown in FIGS. 4 and 5, the engaging portion 35 is integrally provided downward on the bottom surface of the base portion 3. An engagement space 150 is formed in the long rail portion 100. The molding 2 is fixed to the long rail part 100 by inserting the engaging part 35 downward into the engaging space 150 of the long rail part 100 from above. As shown in FIG. 4, the engaging portion 35 includes an engaging neck 351 and an engaging head 352.
