  The molding fixture of Patent Document 1 is configured to adhere to the bottom surface of the groove with an adhesive tape. Since such adhesive tape is thermosetting, it needs to be passed through a drying furnace, and there is a difficulty that requires equipment for that purpose, and storage equipment etc. are required to ensure a constant adhesive force of the adhesive tape. So, overall, the cost was high.

  In the molding fixing structure of Patent Document 2, an upright wall extending in the longitudinal direction is formed at the center of the groove, and two opposing pieces are arranged at an interval between the upright wall and one upstanding side wall of the groove, A wedge piece is pushed between the opposing pieces, and the opposing pieces are pressed and fixed to the standing wall and the upstanding side wall. Using the molding edge locking portion of one of the opposing pieces and the molding edge locking portion of the wedge piece, the inner bending edge of the molding is locked to fix the molding. In this molding fixing structure, no adhesive tape is used, but a standing wall must be made in the groove on the vehicle body side, and the two opposing pieces are pressed against the standing wall and the upstanding side wall by pushing the wedge pieces. The fixing force of the opposing piece is not so strong, and there is a possibility that the fixing is released due to long-term vibration of the vehicle body.

  Patent Document 3 describes a molding fixing structure that closes a gap between a glass edge such as a windshield and a vehicle body edge. The clip of the molding is fixed to the upright side wall of the vehicle body edge by a blind rivet. A blind rivet consists of a hollow rivet body with a flange and a mandrel inserted into the rivet body. Insert the mandrel head into the mounting hole of the panel etc. until the flange of the rivet body comes into contact with the head. When the protruding mandrel is pulled with a tool to such an extent that the mandrel breaks at the small diameter portion, the enlarged head of the mandrel expands the shaft of the rivet body, and the expanded shaft and flanges allow a plurality of Panels are connected to each other. The blind rivet is convenient because the fastening operation can be performed from one direction. Since the clip is fixed to the side wall by the blind rivet, the fixing force of the clip is strong and there is no possibility that the fixing is released even by long-term vibration of the vehicle body. However, this clip is not a fixture for attaching a molding that is attached to the bottom surface of the groove to decorate the groove.

  Therefore, an object of the present invention is to attach a molding that is attached to the bottom surface of the groove and decorate the groove, does not require an adhesive tape, has a high fixing force, and may be released due to long-term vibration of the vehicle body. It is to provide a mall fixture without any.

  In order to achieve such an object, the fixture according to the present invention is fixed to the bottom surface of a groove having at least one side wall, and each of the inwardly bent edges hanging from both edges of the molding decorating the groove. A molding fixture having a molding edge locking portion for locking to a groove, comprising a base fixed to the groove bottom surface, at a position close to one end of the base from one side edge of the molding A first molding edge locking portion that locks to the first inner bending edge that hangs down is formed so as to rise from the base that is fixed to the groove bottom surface, and at a position near the other end of the base, A second molding edge locking portion that locks to a second inward bending edge hanging from the other side edge of the molding is formed so as to rise from a base fixed to the groove bottom surface. The blind rivet that secures the It is held by a blind rivet holding part adjacent to the molding edge locking part, and a pin receiving part is formed on the base at a position between the second molding edge locking part and the blind rivet holding part. The pin receiving portion is formed with a locking claw for locking the pin, and the pin having a multi-stage ratchet claw provided on the shaft portion on the pin receiving portion is locked to the locking claw. The base is formed with a stopper that can contact the side wall adjacent to the second molding edge locking portion, and the pin receiving portion and the pin are pushed into the shaft portion of the pin. The stopper can be deformed so as to contact the side wall.

  According to the above fixing tool, since it can be fixed to the groove bottom surface by the blind rivet, there is no need for an adhesive tape, the fixing force is high, and there is no possibility that the fixing is released even by long-term vibration of the vehicle body. In addition, the fixing tool fixed to the bottom surface of the groove simply inserts the pin into the pin receiving portion of the base, the stopper is brought into contact with the side wall, and the distance between the second molding edge locking portion and the side wall is increased. Since it is maintained constant, when the second inner bending edge of the molding is pushed between the second molding edge locking portion and the side wall, the molding can be properly attached to the position where the molding covers the groove as it is. .

  The fixture is composed of three parts: a base, a pin, and a blind rivet. The base is formed long in a direction transverse to the longitudinal direction of the groove, and the base is formed with a first molding edge locking portion on one end side in the longitudinal direction and the other longitudinal end portion. A second molding edge locking portion is formed on the side, and the second molding edge locking portion becomes a molding edge locking portion facing the side wall. The base is attached to the position where the stopper is opposed to the side wall by the blind rivet, and when the pin is fully pushed into the pin receiving part, the stopper contacts the side wall and the distance between the second molding edge locking part and the side wall is constant. Maintained at the length of The base is formed with a pair of elastic wings that elastically contact the side wall adjacent to the stopper, and the rivet body of the blind rivet is inserted into the hole in the groove bottom surface of the mounted member so that the base becomes the mounted member. When positioned, the elastic wing elastically contacts the side wall to position the base in a proper posture within the groove. The pin receiving portion is formed in a loop shape in which two U-shaped portions are connected by the opening portion, and the pin shaft portion is received at the center position of the loop shape. The stopper is brought into contact with the side wall by deforming to widen the shape. At the center of the loop shape of the pin receiving portion, a pair of elastic locking claws that are locked to the ratchet claw of the pin shaft portion are formed. The pin is composed of a shaft portion and a head portion that is pushed in with a finger or the like formed at one end of the shaft portion. The shaft portion extends in the axial direction with a constant thin width in the length direction of the loop, and In the direction perpendicular to the length direction, the width on the tip end side of the shaft portion is short enough not to deform the pin receiving portion, and the shaft portion on the upper side from the intermediate position to the head is inclined so that the width gradually increases. The loop portion is deformed so that the width of the loop shape is increased as the inclined portion of the shaft portion is inserted into the pin receiving portion.

  The blind rivet preferably has a mandrel and a rivet body, and the sleeve of the rivet body is preferably covered with a covering. The covering is made of plastic, improves water tightness, and electrically insulates blind rivets. The molding is preferably a roof molding that is decorated so as to cover a groove formed in the roof panel. The side wall is a reference upright side wall that rises from the bottom surface of the groove. Two first molding edge locking portions are formed at a position close to one end portion of the base with a gap therebetween, and the second molding edge locking portion is a position close to the other end portion of the base. In addition, two are preferably formed at intervals.

  Hereinafter, a molding fixture 1 according to an embodiment of the present invention will be described with reference to the drawings. A fixing tool 1 according to an embodiment of the present invention is suitable for fixing a roof molding that covers a groove portion formed on a roof edge portion that connects a roof panel and a side panel of an automobile. Also in the illustrated embodiment, a description will be given as a fixture 1 for fixing a roof molding for decorating and closing a groove of the roof to the roof. However, in order to close the groove having at least one side wall with the molding, the fixing tool 1 of the present invention is fixed to the bottom surface of the groove and can be attached so as to close the groove. In addition to fixing, it can also be used as a fixture for other moldings. The side wall is preferably a side wall that becomes a reference side wall and stands upright from the bottom surface of the groove.

  As shown in FIGS. 1 to 5, the fixture 1 is composed of three parts: a base 2, a pin 3, and a blind rivet 5. The detailed configuration of the base 2 is shown in FIGS. 6 to 9, the detailed configuration of the pin 3 is shown in FIGS. 10 to 12, and an example of the blind rivet 5 is shown in FIGS. 13 and 14. It is shown. The base 2 is integrally molded from thermoplastic in a preferred embodiment. The base 2 is fixed to a groove bottom surface of a member to be attached such as a roof panel of an automobile, which forms a groove between side walls. The fixed base 2 has a configuration in which a locking edge portion of the molding that closes the groove is locked, and the molding is attached to the mounted member through the base 2 with the molding closing the groove. A blind rivet 5 is used to fix the base 2 to the groove bottom surface of the member to be attached. In order to fix the base 2 to the groove bottom surface with the blind rivet 5, a hole into which the rivet body of the blind rivet 5 is inserted must be formed at a predetermined position on the groove bottom surface. There is a certain variation in the position and size of the hole within an allowable range. Further, the base 2 fixed by the blind rivet 5 may rotate around the axis of the blind rivet 5 on the bottom surface of the groove. A pin 3 is assembled to the base 2 in order to absorb variations in the position and size of the holes and restrict the base 2 from rotating at the bottom of the groove. When the pin 3 is pushed into the base 2, a part of the base 2 is deformed, and one end of the base 2 is pushed toward the side wall rising from the groove bottom surface. As a result, the base 2 is properly fixed to the bottom surface of the groove, and the base 2 is prevented from rotating around the axis of the blind rivet 5. In particular, the mounting position of the molding can be appropriately determined by maintaining a constant space between the molding edge locking portion provided on the base 2 and one reference side wall.

  That is, the basic configuration of the molding fixture 1 includes a base 2 fixed to the bottom surface of the groove, and a first inward bending edge portion that hangs down from one side edge of the molding at a position close to one end portion of the base. The first molding edge locking portion 6 that locks to the bottom is formed so as to rise from the base fixed to the bottom surface of the groove, and is located near the other end of the base from the other side edge of the molding. A second molding edge locking portion 7 that locks to the second inner bending edge that hangs down is formed to rise from a base that is fixed to the groove bottom surface. The base 2 has a blind rivet 5 for fixing the base to the groove bottom surface held by a blind rivet holding portion 9 adjacent to the first molding edge locking portion, and the base has a second molding edge locking. A pin receiving portion 14 is formed at a position between the portion 7 and the blind rivet holding portion 9. The pin receiving portion 14 is formed with a locking claw 15 for locking the pin 3, and the pin 3 provided with the multi-stage ratchet claw 22 on the shaft portion 23 is connected to the pin receiving portion 14. It is connected by locking to the pawl. The base is formed with a stopper 19 that can abut against the side wall, adjacent to the second molding edge locking portion 7. The pin receiving portion 14 and the pin 3 are moved when the shaft portion of the pin is pushed. It is the structure which can deform | transform so that it may contact | abut to a side wall.

  Details of the base 2 will be described with reference to FIGS. 1 to 5 and FIGS. 6 to 9. The base 2 has an overall shape that is long in the direction transverse to the longitudinal direction of the groove so that the base 2 is stably seated on the bottom surface of the groove between the side walls formed on the attached member. The bottom surface to be seated is formed so as to form a flat surface in accordance with the bottom surface of the groove. The base 2 has two first molding edge locking portions 6 that lock to one inward bending edge of the molding on one end side in the longitudinal direction. Two second molding edge locking portions 7 that lock to the other inward bending edge of the molding are formed on the other longitudinal end portion side of the base 2. The first and second molding edge locking portions 6 and 7 are attached by pressing the molding from the upper part of FIG. In the illustrated embodiment, the second molding edge locking portion 7 becomes a molding edge locking portion facing the upright side wall serving as a reference, and the second molding edge locking portion 7 and the side wall 47 (FIG. 22) 54 is maintained at a constant length. For example, as shown in FIG. 15 and subsequent figures, the reference side wall is a side wall adjacent to the vehicle body edge on the side panel side adjacent to the connecting portion (groove) formed by extending the side panel to the roof panel for connection. is there.

  A blind rivet holding portion 9 on which the blind rivet 5 is mounted and held is formed on the base 2 at a position adjacent to the first molding edge locking portion 6. The blind rivet holding part 9 is formed with a hole 10 through which the rivet body of the blind rivet 5 passes. The size of the hole 10 is formed to be equal to or slightly smaller than the diameter of the rivet body of the blind rivet 5, and when the rivet body penetrates, the blind rivet 5 does not naturally fall due to frictional resistance. Furthermore, the blind rivet holding part 9 is formed with a circular recess 11 for receiving the flange of the rivet body.

  In the base 2, a pin receiving portion 14 that receives and holds the pin 3 is formed between the blind rivet holding portion 9 and the second molding edge locking portion 7. The pin receiving portion 14 receives and holds the pin 3, and when the pin 3 is fully pushed in, a part of the base 2 (the second molding edge locking portion 7 and the left portion in FIG. 7) is moved. 7 is formed in a shape that can be deformed to move in the direction of arrow 13 in FIG. In the illustrated embodiment, the pin receiving portion 14 is formed in a loop shape in which two U-shaped portions are connected by the opening portion in a plan view of FIG. A pair of elastic locking claws 15 that receive the shaft portion of the pin 3 and are engaged with a multi-stage locking step portion (ratchet claw) formed on the shaft portion are provided with a gap 18 ( (See FIG. 9).

  Further, the base 2 is formed with a stopper 19 and elastic wings 21 on both sides thereof at the end opposite to the blind rivet holding portion 9 in the longitudinal direction. The stopper 19 and the elastic wing 21 are pressed against the reference side wall rising from the groove bottom surface of the mounted member, and absorb variations in the size and position of the hole for receiving the rivet body of the blind rivet 5 on the groove bottom surface within an allowable range. The base 2 is restricted from rotating around the blind rivet. The stopper 19 is formed of a flat rigid portion so as to contact the reference side wall rising from the groove bottom surface, and the pair of elastic wings 21 is formed by the base 2 in the groove before the deformation by the pin 3 and before the blind rivet 5 is fastened. It functions to be positioned in an appropriate posture in a balanced manner on the bottom surface. When the base 2 is positioned by the blind rivet 5 in the hole at the bottom of the groove of the mounted member, the pair of elastic wings 21 elastically contact the reference side wall to position the base 2 in an appropriate posture within the groove. Normally, at this time, the stopper 19 is not in contact with the reference side wall (the stopper 19 may be in contact depending on the position of the hole in the groove bottom). After the base 2 is fixed to the bottom surface of the groove by the blind rivet 5 in an appropriate posture, when the pin 3 is sufficiently pushed into the pin receiving portion 14, the stopper 19 moves in the direction of the arrow 17 in FIG. The elastic wing 21 that has elastically contacted the reference side wall is further bent, and the stopper 19 is pressed against the reference side wall. This absorbs variations in the position of the hole for receiving the rivet body of the blind rivet 5 on the bottom surface of the groove, and prevents the base 2 from rotating around the blind rivet 5 in the groove. When the base 2 is positioned by the blind rivet 5 in the hole on the bottom surface of the groove of the mounted member, if the stopper 19 comes into contact with the elastic wing 21 as well, the base 2 is properly aligned with the bottom surface of the groove. Therefore, adjustment by the pin 3 is unnecessary.

  The detail of the pin 3 is demonstrated with reference to FIGS. 1-5 and FIGS. The pin 3 is disposed in the pin receiving portion 14 of the base 2 and is sufficiently opposite to the blind rivet holding portion 9 in a part of the pin receiving portion 14, that is, in the longitudinal direction of the base 2 by being sufficiently pushed by the pin receiving portion 14. The stopper 19 at the end on the side is deformed, and the stopper 19 is moved so as to be pressed against the reference side wall rising from the groove bottom surface of the mounted member. When the stopper 19 abuts, the base 2 is firmly fixed to the bottom surface of the groove of the attached member in a proper posture. In this embodiment, the pin 3 is integrally formed of a thermoplastic material. The pin 3 includes a shaft portion 23 having a multi-stage ratchet claw 22 in the pushing direction, which is locked to the locking claw 15 of the pin receiving portion 14 of the base 2, and a disk-shaped head for pushing the pin 3 with a finger or the like. 25. As shown in the figure, the shaft portion 23 extends with a certain narrow width when viewed from one direction (front direction in FIG. 11), and a cavity 26 is formed in the central portion. When viewed from the direction of FIG. 12, the width of the tip side shaft portion is short enough not to deform the pin receiving portion 14 of the base 2, and the shaft portion 27 on the upper side from the intermediate position to the head portion 25 is The shape is inclined so that the width gradually increases. The cavity 26 gives each ratchet claw 22 the flexibility to bend from the outside to the inside. The width of the inclined shaft portion 27 of the shaft portion 13 is formed such that the pin receiving portion 14 of the base 2 is deformed into an arrow 17 in FIG. Since the width of the inclined shaft portion 27 is gradually increased, the pin receiving portion 14 is gradually moved in the direction of the arrow 17 in FIG. The edge locking part 7 and the stopper 19 are moved so as to contact the side wall of the groove of the attached member.

  The ratchet claw 22 is engaged with the engagement claw 15 of the pin receiving portion 14 of the base 2 so that the pin 3 is connected to the base 2. When the ratchet claw 22 is locked to the locking claw 15, the cavity 26 is bent toward the inner side of the shaft portion 23 to reduce the force at the time of pushing. The ratchet pawl 22 is formed in multiple stages, and when the ratchet pawl 22 on the distal end side of the shaft portion 23 is locked to the locking pawl 15 as shown in FIG. Therefore, the pin receiving portion 14 of the base 2 is not deformed. In this state, the ratchet claw 22 is locked to the locking claw 15, but the pin receiving portion 14 of the base 2 is not deformed, so that the pin 3 is temporarily connected to the base 2. When the pin 3 is further pushed in, the width of the inclined shaft portion 27 is gradually increased, so that the pin receiving portion 14 is gradually moved in the direction of the arrow 17 in FIG. Is moved so as to abut against the side wall of the groove of the mounted member. This state is the final stop state. When the ratchet pawl 22 is locked to the locking pawl 15, the pin 3 is connected to the base 2 in both the temporarily fixed state and the final fixed state. The state of being gradually moved in the direction of the arrow 17 in FIG. 7 is maintained as it is.

  The blind rivet 5 will be described with reference to FIGS. 1 to 5 and FIGS. 13 and 14. The blind rivet used in the embodiment of the present invention may be any known blind rivet as long as it can fix the base 2 to the groove bottom surface and does not interfere with the mounting of the molding after the fixing. The blind rivet 5 used in the illustrated embodiment includes a hollow rivet body 31 formed of a sleeve 29 and a flange 30 at the end of the sleeve 29, and a metal rivet body 31 such as steel. The mandrel 33 is longer than the rivet body 31 inserted into the hollow hole. The mandrel 33 is formed with a head 34 having an enlarged diameter at one end. As shown in the figure, the blind rivet 5 is inserted in the mandrel 33 in the rivet body 31 so that the enlarged head 34 is located at the end of the sleeve 29 opposite to the rivet body flange 30. A portion of the mandrel 33 hidden by the sleeve 29 of the rivet body 31 is formed with a small-diameter portion 35 that becomes a broken portion when the mandrel 33 is pulled strongly. In order to fasten the panel using the blind rivet 5, as shown in FIG. 14, for example, the flange 30 comes into contact with the mounting holes of the two panels 37 and 38 with the mandrel head 34 at the head. Insert the rivet body 31 until In this state, when the fastening tool that holds the exposed portion of the mandrel 33 is operated and pulled so hard that the mandrel 33 is broken at the small diameter portion 35, the enlarged head 34 of the mandrel 33 pulls the sleeve 29 of the rivet body 31. The panel 39 is connected to each other by the buckled diameter-expanded portion 39 of the sleeve 29 and the flange 30. The connection is strong because it can be obtained with the same fastening force as the breaking force of the mandrel 33. Since such blind rivets are well known, further detailed description is omitted.

  The blind rivet 5 used for the fixture 1 is preferably provided with a plastic covering 41 attached to the rivet body 31. The covering 41 is formed in a cap shape that covers the enlarged diameter head 34 of the mandrel 33 and the sleeve 29 of the rivet body 31. The covering body 41 has an advantage of improving the sealing performance (particularly water tightness) of the hole of the member to be fastened at the time of fastening, and has an advantage of electrically insulating the metal blind rivet from the member to be fastened. is there. A blind rivet having a covering 40 is described in, for example, Japanese Patent Laid-Open No. 7-180712.

  In the fixture 1 according to the embodiment of the present invention, the blind rivet 5 is arranged in the base 2 so that the flange 30 contacts the circular recess 11 of the blind rivet holding portion 9 and the sleeve 29 penetrates the hole 10. . The size of the hole 10 is equal to or slightly smaller than the diameter of the sleeve 29 of the rivet body 31 of the blind rivet 5 (or the diameter of the covering 41 when the covering 41 is provided). Therefore, when the sleeve 29 (or the covering body 41) of the rivet body 31 penetrating the hole 10 penetrates, the blind rivet 5 does not naturally fall due to frictional resistance. The blind rivet 5 is held on the base 2 in a state where the flange 30 of the rivet body 31 is in contact with the circular recess 11 of the blind rivet holding portion 9.

  As described above, in the fixture 1, the blind rivet 5 is held by the blind rivet holding portion 9 of the base 2, and the pin 3 is connected to the pin receiving portion 14 in a temporarily fixed state. The state in which the pin 3 is temporarily fixedly connected to the base 2 while being held by the blind rivet 5 base 2 is a delivery state of the fixture 1, and the operator can easily handle it as one article.

  Using the molding fixture 1 having the above-described configuration, the molding is closed at the edge of the roof panel of the automobile as a member to be mounted so as to decorate the groove formed in the connecting portion between the roof panel and the side panel. The operation will be described with reference to FIGS. In FIG. 15, FIG. 16, FIG. 23, and FIG. 24, the roof panel, the side panel (including the groove and the side wall of the connecting portion), and the molding are each shown with a short solid line for convenience of explanation. However, it should be understood that the shape is actually long as shown by the dotted line.

  15-17, the groove | channel 45 formed in the connection part of the roof panel 42 and the side panel 43 of a motor vehicle is formed between the two side walls 46 and the side wall 47, and a connection part is formed in the bottom face 49. In FIG. ing. The side wall serving as a reference for setting the fixture 1 in an appropriate posture is, for example, the side wall 47 and is adjacent to the groove 45 that is a connecting portion formed by extending the side panel 43 to the roof panel 42 for connection. It is a side wall adjacent to the vehicle body edge on the side panel side. A hole 50 (FIG. 17) through which the rivet body 31 (the sleeve 29 or the covering body 41 thereof) of the blind rivet 5 of the fixture 1 is passed is formed in the bottom surface of the groove 45. The hole 50 varies in size and position within an allowable range. The fixture 1 is positioned so that the rivet body 31 of the blind rivet 5 passes through the hole 50 and each of the pair of elastic wings 21 elastically pushes the side wall 47, and the base 2 is seated on the bottom surface 49 of the groove 45. To be arranged. 15 to 17, since the lower surface of the base 2 is seated on the bottom surface 49 of the groove 45, the rivet body 31 penetrates the hole 50, and the pair of elastic wings 21 elastically push the side wall 47 in a balanced manner. The base 2 and thus the fixture 1 are temporarily fixed to the groove 45 in an appropriate posture.

  In the temporarily fixed state, the blind rivet 5 held by the blind rivet holding portion 9 of the base 2 is fastened to the roof panel 42 which is a member to be attached by a blind rivet fastening tool. The state in which the base 2 is fastened to the roof panel 42 is shown in FIGS. The blind rivet 5 is fastened in the manner described with reference to FIG. That is, the mandrel 33 is strongly pulled out by the fastening tool, the mandrel 33 is broken at the small diameter portion 35 (FIG. 13), and a part 39 of the sleeve 29 of the rivet body 31 is expanded in diameter. 30, the base 2 and the roof panel 42 are strongly connected to each other. As a result, the base 2 and thus the fixture 1 are firmly fixed to the bottom surface 49 (roof panel 42) of the groove 45. In this state, a gap 51 is usually formed between the side wall 47 and the stopper 19 due to variations in the size and position of the hole 50 as shown in FIG. As shown in FIG. 19 (and FIG. 5), a ratchet claw 22 on the tip end side of the shaft portion 23 of the pin 3 is locked to the locking claw 15 of the pin receiving portion 14, and the pin receiving portion 14 is 3 is not deformed. In a state where there is a gap 51, the pair of elastic wings 21 are only in contact with the side wall 47, and therefore the base 2 may rotate when a strong rotational force acts around the axis of the blind rivet 5, The mounting posture of the base 2 is not stable.

  In order to stabilize the mounting posture of the base 2, as shown in FIGS. 20 to 22, the pin 3 is sufficiently pushed toward the pin receiving portion 14 of the base 2 from the temporarily fixed state as indicated by an arrow 52. Include. Since the width of the inclined shaft portion 27 of the shaft portion 13 of the pin 3 is gradually increased, the pin receiving portion 14 is gradually moved in the direction of the arrow 53 in FIG. 20 as the pin 3 is pushed. By this movement, as shown in FIGS. 21 and 22, the second molding edge locking portion 7 and the stopper 19 of the base 2 are moved toward the side wall 47 of the groove of the attached member, and the stopper 19 is moved to the side wall 47. It is made to contact. In the illustrated embodiment, the side wall 47 is utilized as a reference side wall for mounting the mall. By sufficiently pushing the pin 3, the gap 51 (FIG. 18) between the stopper 19 and the side wall 47 disappears. Accordingly, as shown in FIG. 22, the base 2 is not only securely fixed in a stable posture on the bottom surface 49 of the groove 45, but also has a length 54 between the second molding edge locking portion 7 and the side wall 47. Is set to a certain length. Since the space between the second molding edge locking portion 7 and the reference side wall 47 is maintained constant, the mounting position of the molding can be determined appropriately. The pushing-in of the pin 3 is stopped when the stopper 19 comes into contact with the side wall 47, whereby the variation in the size and position of the hole for receiving the rivet body of the blind rivet 5 on the bottom surface of the groove can be absorbed. Since the stopper 19 contacts the side wall 47, the base 2 is prevented from rotating around the blind rivet 5 in the groove. When the base 2 is positioned by the blind rivet 5 in the hole at the bottom of the groove of the mounted member, not only the elastic wing 21 but also the stopper 19 comes into contact (it is considered extremely rare). Thus, the base 2 is properly fixed to the groove bottom surface, and adjustment by the pin 3 is not necessary.
