Since the configuration and operation are the same as those of the conventional one in FIG. 9, the same or corresponding parts are denoted by the same reference numerals, and the description thereof is omitted. Here, the fitting portion 21 and the attachment clip 26 are formed as attachment means.
[0025]
The difference between the pillar garnish 20 of the embodiment and the conventional one is that the mounting clip 26a provided on the side fixing window 3 side of the back surface of the main body 25 in FIG. 9 and the pillar 6 corresponding thereto are provided. The attachment holes 15a and the grommets 16a are omitted, and a plurality of engagement holding portions 31 are provided at the corresponding positions of the pillar garnish 20. Thus, the mounting clip 26 as the mounting means is provided on the door glass 4 side of the pillar garnish 20, and the side fixing window 3 side as the adjacent other member is positioned and fixed by the engagement holding portion 31.
[0026]
The engagement holding part 31 is located at a position moved from the base 32 formed on the back surface 25a of the main body 25 in a direction along the back surface 25a and in a direction away from the back surface 25a. Are connected to each other in a state of being separated from the back surface 25a.
[0027]
The locking member 33 has an inclined guide portion 35 that moves the locking member 33 due to interference with the frame member 12 of the side fixing window 3 that is an adjacent other member on the interference side, and a restored position after the interference cancellation. 2 has a stepped engagement portion 36 that engages with the frame member 12 on the opposite side. Corresponding to the engaging portion 36, the stepped engaging portion 17 is also formed in the frame member 12. An inclination angle α is formed on the side wall 33 a that contacts the frame member 12 of the locking member 33, and an inclination angle β is formed on the engaging portion 36. The guide portion 35 is formed with a height difference d so that the upper portion has an acute angle.
[0028]
The connecting member 34 is elastically deformed so as to move the locking member 33 in the P direction away from the frame material 12 due to interference between the locking member 33 and the frame material 12, and is restored in the Q direction when it approaches the frame material 12 again by releasing the interference. Thus, the space 37 is formed between the back surface 25a and the back surface 25a. The space 37 is formed in a non-linear shape (bent shape).
[0029]
In this way, when the pillar holding garnish 20 is pressed against the vehicle body and attached to the vehicle body by the attachment clip 26, the engagement holding portion 31 is pushed by the side fixing window 3 which is an adjacent other member and elastically deformed, and then is restored by the restoring force. The side fixing window 3 is configured to be engaged. In this case, the engagement holding part 31 is formed so that the front end of the frame member 12 hits an intermediate part of the inclined guide part 35, and thereby the locking member 33 is configured to be retracted in an inclined state. Is preferred.
[0030]
The above-described pillar garnish 20 as a resin molded product for a vehicle is engaged with the engaging portions 11c and 11d by inserting the fitting portion 21 into the fitting recess 11e of the drip molding 11 in the same manner as conventionally considered. Thus, the positioning in the vertical direction and the horizontal direction is performed, and the body portion 25 is pushed in the protruding direction of the mounting clip 26, whereby the mounting clip 26 is inserted and engaged with the grommet 16 and attached to the pillar 6.
[0031]
At this time, when the main body portion 25 and the engagement holding portion 31 are pressed toward the pillar 6 from the outside of the vehicle, the guide portion 35 of the locking member 33 of the engagement holding portion 31 as shown in FIGS. Interferes with the frame member 12 of the side fixing window 3 as another adjacent member, and receives a lateral force that is substantially perpendicular to the pressing direction. Therefore, as shown in FIGS. 6A and 6B, the connecting member 34 that connects the locking member 33 and the base portion 32 is elastically deformed, and the locking member 33 moves in a direction away from the frame member 12. It passes through the periphery of the frame member 12. When the interference is thereby released, the locking member 33 is restored to the original position as shown in FIGS. 6C and 6D by the springback force of the connecting member 34 itself, and the engaging portion 36 is adjacent. Engage with the engaging portion 17 of the frame member 12.
[0032]
In this state, the frame member 12 of the side fixing window 3 as an adjacent other member is sandwiched between the locking member 33 and the main body portion 25, and the main body portion 25 of the pillar garnish 20 is fixed to the side as an adjacent other member. It is held in the window 3. Thus, the main body 25 is attached to the pillar 6 in a state of being positioned so as to maintain a certain positional relationship with the adjacent side fixing window 3. For this reason, even when there is a variation such as a dimensional error between them, a defect such as a gap does not occur, and an excellent aesthetic feeling can be maintained.
[0033]
In the above embodiment, since the guide portion 35 of the locking member 33 is formed in an inclined shape, the locking member 33 can be easily moved and overcome. Further, since the connecting member 34 is formed in a non-linear shape (bent shape), the substantial length is longer than the linear distance, the elastic deformation is easy, and the locking member 33 can be easily climbed over. Even if there is a variation in the dimensions and mounting position of the frame member 12, the variation is absorbed by the elastic deformation of the connecting member, and the locking member 33 gets over and engages easily and accurately.
[0034]
In the above-described configuration, the locking member 33 is provided with a guide portion during the rotation of the connecting member 34 by bending the both side walls with a height difference of about 0.3 to 1 mm as shown in FIG. It is possible to prevent 35 from biting into the frame member 12. Further, as shown in FIG. 6C, the side wall of the locking member 33 is inclined 20 to 40 degrees as the receding angle α, thereby reducing the amount of deflection of the connecting member 34 when the locking member 33 gets over. be able to. Further, when the engaging portion 36 is provided with an inclination angle of 3 to 7 degrees as the inclination angle β, a pulling force is applied even after the engagement is completed, and the variation in the thickness direction of the frame member 12 is absorbed and firmly held. be able to.

In the above-described embodiment, the pillar garnish is integrally formed of the resin having the main body portion 25 and the engagement holding portion 31 having elasticity, so that the manufacture is easy and the dimensional stability is relatively high.
[0036]
FIG. 7 is a cross-sectional view taken along the line DD of FIG. 1 showing another embodiment, and FIG. 8 is a perspective view of a part of the back surface side showing an attachment state.
In this embodiment, the engagement holding part 31 is formed separately from a resin rich in elastic deformation different from the main body part 25, and this is integrally formed by embedding the base part 32 in the main body part 25 by insert molding. Other configurations, operations, and effects are the same as those shown in FIGS.
[0037]
Since the pillar garnish 20 can form the main body portion 25 and the engagement holding portion 31 with different resins, it is possible to use resins suitable for the respective characteristics. For example, the main body can be made of a hard and rigid resin such as an acrylic resin or an AS resin. On the other hand, an elastically deformable resin such as polyamide, polyacetal, polypropylene, or ABS resin can be used for the engagement holding portion 31, and a metal material such as spring steel or stainless steel can be used depending on circumstances. Further, the engagement holding part 31 can be fixed to the main body part 25 by a method such as adhesion, screwing, or caulking with a boss.
[0038]
In the above-described embodiment, the present invention can be similarly applied even when the frame member 12 is not provided. Moreover, although said example is related to a pillar garnish, this invention is applicable also to the other resin molded product for vehicles attached adjacent to another member. In this case, it is possible to form a main body portion, attachment means, and engagement holding portion having a shape and structure corresponding to each.
