It may be an insignificant part.

  Therefore, the front door 11 of the first specification forms the large door pocket 20 by bringing the partition wall 17a of the door pocket forming member 15 of the first specification into contact with the first partition contact portion 14b of the door lining 14 and has a small area. A small side bump pad 19 is attached to the support portion 18a (see FIG. 5). At this time, the second partition abutting portion 14c of the door lining 14 does not function. Further, the front door 11 of the second specification forms a small door pocket 20 by bringing the partition wall 17b of the door pocket forming member 15 of the second specification into contact with the second partition contact portion 14c of the door lining 14, thereby forming a large area. A large side impact pad 19 is attached to the support portion 18a (see FIG. 6). At this time, the first partition abutting portion 14b of the door lining 14 does not function.

  Thus, according to this embodiment, one type of door lining 14 is shared by the first specification and the second specification, and the door pocket forming member 15 is made of two types of members of the first specification and the second specification. As a result, it is possible to configure the front door 11 having two specifications while minimizing the types of components, thereby contributing to cost reduction.

  Moreover, the door pocket forming member 15 is integrally provided with an armrest portion 18, and the armrest portion 18 protrudes from the opening portion 14 a formed in the door lining 14 into the vehicle interior, so that the armrest portion 18 is made up of independent parts. In addition, the number of parts and assembly man-hours can be reduced, contributing to cost reduction.

  The embodiments of the present invention have been described above, but various design changes can be made without departing from the scope of the present invention.

  For example, the door of the present invention is not limited to the front door 11 of the embodiment, and may be a rear door.

  Moreover, although the door pocket formation member 15 of embodiment is two types of 1st specification and 2nd specification, three or more types may be sufficient.
