  However, when a stress is generated in the outer member due to the fastening between the channel and the guide seal, the design surface of the outer member is distorted.

  In view of the above fact, the present invention provides a fastening structure between a channel and a guide seal that can prevent or suppress distortion of the design surface of the outer member of the guide seal due to fastening between the channel and the guide seal. The purpose is to obtain.

The fastening structure of the channel and the guide seal according to the first aspect of the present invention is attached to the vertical frame of the window opening of the vehicle door to close the corner of the window opening, and the edge of the door glass that moves up and down is provided. A guide seal formed with a groove-shaped portion passing therethrough, and a channel formed inside the groove-shaped portion and formed with a guide groove portion for guiding the raising and lowering of the door glass. The inner wall of the guide seal is formed including a side wall on the vehicle interior side of the groove-shaped portion, and a first facing portion facing the groove bottom wall of the channel is formed. A resin inner member with a groove bottom wall fastened, and an outer side wall of the groove member disposed outside the passenger compartment of the inner member constitute the outer plate of the guide seal. Channel groove bottom wall An opposing second opposing portion is formed, and the second opposing portion is disposed on the side of the groove bottom wall of the channel with respect to the first opposing portion and is made of resin that is engaged with the first opposing portion An outer member, and the second facing portion has a screw hole that forms a fastening portion with the channel at a part of the first facing portion and a peripheral portion thereof facing the groove bottom wall side of the channel. A convex portion that penetrates the through portion and abuts against a groove bottom wall of the channel is formed in the first opposing portion, and a protruding amount of the convex portion is the second opposing portion. The convex portions are formed on both sides of the bolt head when viewed in the axial direction of the bolt that fastens the groove bottom wall of the channel and the first facing portion. Is set .

  According to the above configuration, the guide seal is configured such that the first facing portion of the inner member and the second facing portion of the outer member both face the groove bottom wall of the channel and constitute the bottom wall side of the groove-shaped portion. The two opposing parts are engaged with the first opposing part. For this reason, the shape of the groove-shaped part of a guide seal can be stabilized. Further, a groove bottom wall of the channel is fastened to the first facing portion of the inner member, and the elevation of the door glass is guided by the channel guide groove.

  Here, the second facing portion of the outer member is formed with a screw hole that forms a fastening portion with the channel at a part of the first facing portion and a through portion that allows the surrounding portion to face the groove bottom wall side of the channel. And the convex part which penetrated the penetration part and was abutted against the groove part bottom wall of the channel was formed in the 1st opposing part of an inner member. And since the protrusion amount of a convex part is set larger than the plate | board thickness of a 2nd opposing part, even if the groove part bottom wall of a channel is fastened to the 1st opposing part of an inner member, the 2nd opposing of an outer member The fastening load does not reach the part. Thereby, distortion of the outer member due to fastening of the channel and the guide seal is prevented or suppressed.

(Operation and effect of the embodiment)
Next, the operation and effect of the above embodiment will be described.

  In the present embodiment, as shown in FIG. 3, the guide seal 30 is such that the first facing portion 50 of the inner member 40 and the second facing portion 60 of the outer member 44 are both opposed to the groove bottom wall 38 </ b> A of the channel 36. The groove portion 32 (see FIG. 5) constitutes the bottom wall side, and the second facing portion 60 is engaged with the first facing portion 50. For this reason, the shape of the groove-shaped part 32 of the guide seal 30 shown in FIG. 5 can be stabilized. Further, a groove bottom wall 38A of the channel 36 shown in FIG. 1 is fastened to the first facing portion 50 of the inner member 40, and the raising and lowering of the door glass 28 (see FIG. 4) is guided by the guide groove 38 of the channel 36. Is done.

  Here, as shown in FIG. 3, the second facing portion 60 of the outer member 44 has a screw hole 56 </ b> A formed in the first facing portion 50 of the inner member 40 and its peripheral portion as a groove bottom wall of the channel 36. A notch 60A (see FIG. 5) is formed to face the side of 38A. Further, the first opposing portion 50 of the inner member 40 is formed with ribs 58 and 59 that pass through the notch portion 60A and are abutted against the groove bottom wall 38A of the channel 36. Is set larger than the plate thickness of the second facing portion 60. For this reason, even if the groove bottom wall 38 </ b> A of the channel 36 is fastened to the first facing portion 50 of the inner member 40, the fastening load does not reach the second facing portion 60 of the outer member 44. Thereby, distortion of the outer member 44 resulting from fastening of the channel 36 and the guide seal 30 is prevented or suppressed.

  Here, a supplementary explanation will be given by taking a contrast structure as an example. For example, in the contrast structure in which the ribs 58 and 59 of the present embodiment are not provided, when the channel is fastened to the bottom of the groove-shaped portion, the portion corresponding to the second facing portion 60 of the present embodiment is the channel and the inner portion. It will be sandwiched between a part of the members (a component obtained by removing the ribs 58 and 59 from the first facing portion 50 of the present embodiment). For this reason, stress will generate | occur | produce in an outer member. On the other hand, in the present embodiment, the protruding amount of the ribs 58 and 59 is set to be larger than the plate thickness of the second facing portion 60, so that the channel 36 and the guide seal 30 are fastened. The generation of stress in the outer member 44 can be prevented or suppressed.

  For example, as another contrast structure, for example, a portion constituting the bottom of the groove-shaped portion in the outer member (hereinafter referred to as “the bottom component of the outer member”) forms the bottom of the groove-shaped portion in the inner member. With a structure that is disposed on the side opposite to the channel side with respect to the site (hereinafter referred to as “the bottom component of the inner member”), it is possible to prevent or suppress the occurrence of stress in the outer member. The following problems will occur.

  First, when focusing on the NV performance (noise and vibration performance) of the other contrast structure, the following can be said. That is, in the other contrast structure, even if the bottom structure portion of the inner member is designed to abut against the outer flat plate portion of the outer member (see reference numeral 46 in FIG. 4 of this embodiment), the bottom structure of the inner member In the corner portion formed by the groove portion and the side wall outside the vehicle compartment of the groove-shaped portion (that is, a part of the outer flat plate portion of the outer member, see reference numeral 32B in FIG. 4 of this embodiment). Due to this, a gap may occur. For this reason, even if a sealing material for sealing between the corner portion and the channel is arranged inside the corner portion, there is a possibility that the wind path during vehicle travel may not be blocked. If it is not possible to close the network, the NV performance cannot be improved. For this reason, it is difficult to adopt the other contrast structure from the viewpoint of NV performance.

  Next, the following can be said when focusing on the formability of the other contrast structure. That is, in the other contrast structure, for engagement between the bottom component of the inner member and the bottom component of the outer member, an engagement claw is formed on the bottom component of the inner member and the bottom component of the outer member is A configuration in which an engagement hole for engaging (fitting) with the engagement claw is considered. In this case, considering the protruding direction of the engagement claw of the inner member, the engagement claw is formed due to the structure of the mold. Is difficult. On the other hand, in the other contrast structure, for engaging the bottom component of the inner member and the bottom component of the outer member, an engagement claw is formed in the bottom component of the outer member and the bottom component of the inner member is Although the structure which forms the engagement hole engaged with an engagement nail | claw (fitting) can be considered, sink marks may generate | occur | produce on the design surface of an outer member in this case. For this reason, it is difficult to adopt the other contrast structure from the viewpoint of moldability.

  On the other hand, in this embodiment, the malfunction like the said other contrast structure does not arise.

  In the present embodiment, as shown in FIG. 1, the ribs 58 and 59 are seen in the axial direction of the bolt 68 that fastens the groove bottom wall 38A of the channel 36 and the first facing portion 50 (see FIG. 3). Thus, it is set on both sides of the head 68B of the bolt 68. Thereby, the distance from the abutment surface 58A of one rib 58 to the abutment surface 59A of the other rib 59 is, for example, a case where a portion facing the bolt head at the peripheral portion of the screw hole is a convex portion. It is set longer than the diameter of the abutting surface of the convex portion. For this reason, the ribs 58 and 59 of the inner member 40 can stably receive the fastening load between the channel 36 and the guide seal 30.

  In the present embodiment, as shown in FIG. 3, the ribs 58 and 59 are set on both upper and lower sides with respect to the bolt 68 that fastens the groove bottom wall 38 </ b> A of the channel 36 and the first facing portion 50. . For this reason, for example, as compared with the case where the ribs are set on both the left and right sides with respect to the bolt, the interval between the ribs 58 and 59 can be set wider, and the abutting surfaces 58A and 59A of the ribs 58 and 59 can also be set. The length along the direction in which the ribs 58 and 59 are arranged can be set long. For this reason, the ribs 58 and 59 of the inner member 40 can receive the fastening load between the channel 36 and the guide seal 30 more stably. As a result, the fastening load between the channel 36 and the guide seal 30 can be more effectively prevented or suppressed from acting on the outer member 44 side from the channel 36 side.

  As described above, according to the fastening structure of the channel 36 and the guide seal 30 of the present embodiment, the design surface 46A of the outer member 44 of the guide seal 30 is distorted due to the fastening of the channel 36 and the guide seal 30. Can be prevented or suppressed.

(Supplementary explanation of the embodiment)
In the above embodiment, the cutout 60A is formed in the second facing portion 60 of the outer member 44. Instead of this cutout, the channel (36) is partly formed in a part of the first facing portion (50). A screw hole (56A) constituting the fastening portion and a through hole serving as a through portion that allows the peripheral portion thereof to face the groove bottom wall (38A) of the channel (36) may be formed.

Moreover, in the said embodiment, as FIG. 1 shows, the ribs 58 and 59 as a convex part are set to the both sides which pinched | interposed the head 68B of the volt | bolt 68 seeing in the axial direction of the volt | bolt 68. The setting position of the convex portion is not limited to this. That is, for example, the convex part is a part such as a convex part in which the peripheral part of the screw hole that constitutes the fastening part with the channel is a part of the first facing part and is a contact surface to the groove bottom wall of the channel. It may be a convex part. However, on both sides of the head (68A) of the bolt (68) as viewed in the axial direction of the bolt (68) that fastens the bottom wall (38A) of the groove of the channel (36) and the first facing portion (50). The configuration in which the convex portion is not set is not an embodiment of the present invention but a reference example.

Furthermore, in the said embodiment, although the ribs 58 and 59 as a convex part are set to the up-and-down both sides with respect to the volt | bolt 68, the setting position of a convex part is not limited to this. That is, the convex part is, for example, a bolt that fastens the convex part set on the left and right sides with respect to the bolt that fastens the groove bottom wall of the channel and the first opposing part, or the bolt that fastens the groove bottom wall of the channel and the first opposing part. The convex part etc. which were set continuously or intermittently so that the outer periphery of this may be enclosed may be sufficient. However, on both sides of the head (68A) of the bolt (68) as viewed in the axial direction of the bolt (68) that fastens the bottom wall (38A) of the groove of the channel (36) and the first facing portion (50). The configuration in which the convex portion is not set is not an embodiment of the present invention but a reference example.

  In the above embodiment, the guide seal 30 and the channel 36 are provided on the rear side door 14 (see FIG. 6). However, a configuration in which the guide seal and the channel are provided on the front side door may be employed.

  In addition, the said embodiment and the above-mentioned some modification can be implemented combining suitably.

  Although an example of the present invention has been described above, the present invention is not limited to the above, and it is needless to say that various modifications can be made without departing from the spirit of the present invention. .
