  That is, as described above, the steering mechanism 10 is installed at the center in the vehicle width direction of the instrument panel 8, and the front seat 5 is installed at the center in the vehicle width direction on the floor panel 6 correspondingly. In the vehicle, for example, an occupant (driver) seated in the front seat 5 tries to go to the base of the floor side portion 12 on the side of the front seat 5 in order to get out of the vehicle or get into the vehicle interior. In some cases, the posture is unstable with one leg standing. At this time, if the sub member 26 is provided on the side portion of the instrument panel 8 as described above so as to be exposed in the vehicle interior, the occupant holds the assist grip including the exposed portion of the sub member 26. Since it can get out of a vehicle interior, the operation | movement can be performed smoothly with the stable attitude | position. This is the same when the rear seat occupant seated in the rear seat 7 gets in and out of the passenger compartment.

  In addition, since a part of the sub member 26 for reinforcing the instrument panel member 21 is configured to be usable as an assist grip, it is possible to achieve both the reinforcement of the instrument panel member 21 and the assistance for the passenger to get on and off at a lower cost. Is possible. That is, without exposing the sub member 26 in the vehicle interior, an occupant's getting-on / off operation can be performed by protruding an assist grip made of a U-shaped rod-like body separate from the sub member 26 on the wall surface of the instrument panel 8 or the like. However, with such a configuration, there is a problem that the number of parts increases and the manufacturing cost increases, and the aesthetic appearance of the passenger compartment is impaired. On the other hand, as in the above-described embodiment, by providing the recessed portion 32 in the side portion of the instrument panel 8, a part of the sub member 26 is exposed in the vehicle interior, and the exposed portion can be used as an assist grip. When the sub member 26 is configured to have two functions of reinforcing the instrument panel member 21 and assisting the passenger in getting on and off, the instrument panel member 21 is strengthened and the passenger gets on and off. Can be efficiently realized only by the sub-member 26, and there is an advantage that the aesthetic appearance of the passenger compartment can be favorably maintained with design.

  Further, in the above-described embodiment, the front seat 5 is disposed at the center in the vehicle width direction on the floor panel 6, and the pair of left and right rear seats 7 in which the rear portion of the front seat 5 is disposed behind the front seat 5. Since the front seat 5 and the rear seats 7 and 7 are disposed close to each other so as to overlap with the side view, the front and rear dimensions of the indoor space can be secured while ensuring the number of passengers that can be boarded. In addition to being able to prevent the vehicle from becoming large, there is an advantage that the vehicle body can be effectively made compact and light by efficiently disposing both the front seat 5 and the rear seat 7.

  In the above embodiment, the front seat 5 corresponding to the seating width of one occupant is installed at the center in the vehicle width direction on the floor panel 6, and the front seat 5 is viewed from the left and right in plan view. By installing the pair of left and right rear seats 7, 7 in such a position as to be sandwiched, the longitudinal dimension of the indoor space is further suppressed. However, in a vehicle in which the longitudinal dimension can be ensured to some extent, It is also possible to install the seats 7, 7 at positions separated from the installation part of the front seat 5 by a predetermined distance rearward. In this case, the front seat 5 may be constituted by a so-called bench seat type seat by setting the seat width of the front seat 5 to a dimension in the vehicle width direction so as to occupy substantially the entire vehicle width direction. Good. In this way, there is an advantage that a wider seating space for the driver can be secured and the surplus portion of the front seat can be used as an installation location for passenger luggage or the like.
