In addition, rib portions 55 are formed on the back side of the front locking portion 37 at positions corresponding to the front and rear of the fixed protrusion 45a. The rib portions 55 and 55 are formed so as to be continuous with the lower ends of the guide ribs 52 and 52 at the rotation position where the cut portion 44a of the hinge portion 44 is closed.

  In addition, the fitting claw 45b protrudes toward the vehicle inner side (instrument panel 25 side) so as to face the locked portion 53, and the cutout opening 51 is provided at a position where the hinge portion 44 is in a natural state. And is separated from the locked portion 53, and the tip is located on the extension line of the lower end of the locked portion 53.

  Also, the rear locking portion 38 shown in FIG. 2 protrudes downward with respect to the front end side of the rear protruding portion 57 as the (other) internal protruding portion that protrudes from a part of the wall portion 36 near the front side. It is installed and united. Therefore, the rear locking portion 38 is integrally fixed to the garnish main body 31. Further, the rear locking portion 38 has a front end portion 38a formed in a straight line along the vertical direction, and a lower rear end portion 38b formed by gradually inclining toward the lower end (front end) toward the front side. Has been. For this reason, the rear locking portion 38 is formed so as to gradually narrow in the front-rear direction toward the distal end side. Further, the front end portion 38c of the rear locking portion 38 is formed to bend to the outside, that is, the vehicle inner side (instrument panel 25 side). Further, similarly to the front protrusion 43, the rear protrusion 57 protrudes toward the lower side of the lower bending portion 33 along the direction intersecting the wall 36. For this reason, the entire upper side of the rear locking portion 38 is covered with the lower curved portion 33 and is in a position where it cannot be directly seen from above the lower curved portion 33. The rear locking portion 38 is inserted into a rear locking hole (not shown) as a (other) locking hole provided through the bottom of the recess 46 (FIG. 4) of the instrument panel 25. Stopped.

  The garnish branch portion 32 covers at least a part of the sub-pillar 16 on the side of the passenger compartment 19 (FIG. 6), and an instrument panel 25 (see FIG. A locking projection 59 inserted and locked in 6) is projected in a straight line along the vertical direction. The locking projection 59 is inserted and locked in an insertion locking hole (not shown) provided on the side of the instrument panel 25.

  When the front pillar garnish 21 is manufactured, one mold (core mold) 61 which is one mold shown in FIGS. 5A and 5B and the other mold which is the other mold. A mold (cavity mold) 62 is used.

  One mold 61 is formed with a protrusion 61a corresponding to the notch 44a of the hinge 44. Further, the other mold 62 is formed with a protruding portion 62a whose front end side corresponds to the fitting claw 45b so as to protrude toward the one mold 61 side. Therefore, the hinge portion 44 and the fixed portion are formed by injecting and filling molten synthetic resin into a space (cavity) 64 formed by matching the molds 61 and 62, and cooling and solidifying. A front pillar garnish 21 in which 45 is formed is formed. The position of the base end side of the convex portion 62a corresponds to the notch opening 51.

  When the molded front pillar garnish 21 is assembled in the vehicle compartment 19, first, as shown by the solid lines in FIGS. 4A and 4B, the front locking portion 37 is locked to the front locking portion. Align with the hole 47. At this time, since the hinge portion 44 is in a natural state, the front locking portion 37 is positioned along the garnish main body 31 and can move freely with respect to the garnish main body 31 together with the fixing portion 45. Therefore, when the front end portion 37c of the front locking portion 37 is to be inserted into the front locking hole 47 from above, that is, the front locking portion 37 (the front end portion 37c) is aligned vertically. In this state, the garnish body 31 is in a state where it is slightly laid down (fall down) toward the vehicle interior (right side in FIG. 4) relative to the position directly above the front locking portion 37, and the back surface of the garnish body 31 On the side, the operator works while observing the positional relationship between the front locking portion 37 and the front locking hole 47 from behind or above in the gap between the front pillar 15 (FIG. 6) and the garnish body 31. it can.

  Next, the front pillar garnish 21 is roughly positioned with the front locking portion 37 aligned with the front locking hole 47, as shown by the imaginary lines in FIGS. 4 (a) and 4 (b). The garnish body 31 of the front pillar garnish 21 is inserted into the front locking hole 47 while the front locking portion 37 is inserted into the front locking hole 47, and the front pillar 15 and the sub pillar 16 (see FIG. 6) By rotating in the direction of approaching (to the left in FIG. 4), the fixing portion 45 is guided by the guide ribs 52, 52 (FIG. 1), and the fitting claw 45b is moved to the locked portion 53. As a result of the locking, the front locking portion 37 stands up (rises) with respect to the lower curved portion 33 of the garnish body 31 along the vertical direction substantially perpendicular to the front protrusion 43. The relative position between the garnish body 31 and the front locking portion 37 is fixed The At the same time, the rear locking portion 38 and the locking protrusion 59 are inserted and locked in the rear locking hole and the insertion locking hole, respectively. Further, the upper end portion of the garnish main body 31 is fitted and fixed to the ceiling cover 24 (FIG. 6). In this state, the wall portion 36 of the garnish main body 31 is in close contact with the side portion of the recess 46, the garnish main body 31 covers the compartment 19 side of the front pillar 15 (FIG. 6), and the front locking portion 37 is the front portion. The front pillar garnish 21 is positioned between the ceiling cover 24 and the instrument panel 25 with the garnish branch 32 covering the compartment 19 side of the sub-pillar 16 (FIG. 6). Along the design surface 24a and the design surface 25a.

  As described above, according to the present embodiment, the garnish main body 31 and the front portion locking portion 37 can be relatively rotated by the hinge portion 44, so that these garnish main bodies 31 can be used during assembly work. The front locking portion 37 and the front locking portion 37 and the front locking hole 47 on the side of the instrument panel 25 are easily viewed, that is, the garnish main body 31 is slightly moved toward the passenger compartment. It becomes possible to make the position relationship lie down, and the workability of the assembly can be improved. Further, after aligning the front locking portion 37 with the front locking hole 47 on the side of the instrument panel 25, the garnish is set so that the garnish main body 31 and the front locking portion 37 are in a predetermined positional relationship. By rotating the main body 31 relative to the front locking portion 37 at the hinge portion 44, the fixing portion 45 is locked and fixed to the locked portion 53 of the garnish main body 31, and the garnish main body 31 is moved to the front. Covering the pillar 15 (FIG. 6), the front locking portion 37 is inserted and locked into the front locking hole 47 on the side of the instrument panel 25, so that it can be reliably assembled in a short time.

  In particular, in the front pillar garnish 21 in which the front locking portion 37 and the like are located below the lower curved portion 33 formed at one end of the garnish main body 31, the operator can connect the front locking portion 37 and the front locking portion. Although it is not easy to look directly at the stop holes 47, etc., it is possible to work with the garnish main body 31 laid down as described above, so even on the front pillar garnish 21 with the lower curved portion 33, work can be performed while reliably observing. , Workability can be improved.

  Further, when the front pillar garnish 21 is assembled, even if the front locking portion 37 contacts the design surface 25a of the instrument panel 25, the front locking portion 37 is rotated by the hinge portion 44. It is difficult to apply a load to the instrument panel 25 by escaping. Therefore, even if the assembling work of the front pillar garnish 21 is somewhat difficult to see, the design locking surface 25a of the instrument panel 25 is hardly damaged by the front locking portion 37, and the quality during the assembling work is further improved.

  Then, by bending the front end portion 37c of the front locking portion 37, when the front locking portion 37 is aligned with the front locking hole 47 and inserted from above, the garnish main body 31 is more twisted. Since the work can be carried out while lying largely inside the vehicle, the front locking part 37 and the front locking hole 47 can be more easily seen and workability can be further improved.

  Further, the hinge portion 44 connects the garnish main body 31 and the front locking portion 37 so as to be relatively rotatable in a range of more than 0 ° and not more than 45 °, so that the garnish main body 31 and the front locking portion are connected. 37 to prevent the front locking portion 37 from over-rotating and preventing the front locking portion 37 from falling excessively and becoming difficult to insert into the front locking hole 47. The workability at the time of insertion locking to the front locking hole 47 on the side of the instrument panel 25 can be further improved.

  Further, when the garnish body 31 and the front locking portion 37 are relatively rotated by the hinge portion 44, the fixing portion 45 is guided to the locked portion 53 by the guide ribs 52, 52 (FIG. 1). Thus, the fixing portion 45 can be reliably locked and fixed without being displaced with respect to the locked portion 53.

  Then, by setting a notch opening 51 in the wall portion 36 of the garnish main body 31 at a position corresponding to the fixed portion 45, a general position can be obtained by the same mold structure as the conventional shape without adding a slide structure or the like. The fixing portion 45 can be molded using the mating surface (parting line), and can be handled without increasing the manufacturing cost of the mold more than necessary.

  In the above-described embodiment, for example, the rear locking portion 38 or the locking protrusion 59 is also a hinge structure similar to the front locking portion 37 (the same structure as the hinge portion 44 and the fixing portion 45). Thus, the garnish main body 31 (and the garnish branch part 32) may be pivotally connected.

  Further, the garnish branching portion 32 may be provided only when the vehicle body 10 includes the sub pillar 16 and is not an essential configuration.

  Furthermore, the said interior material is applicable not only to a vehicle but as an interior material which covers a columnar part with respect to the arbitrary structures with which an adjacent interior material adjoins the side part of a columnar part.

  The present invention can be suitably used as, for example, a front pillar garnish that covers a passenger compartment side of a front pillar of an automobile.
