  In order to fix the bumper and radiator grill to the front of the body, there is a structure using a bumper support member and a grill bracket. In such a structure, when assembling the bumper and the radiator grille, the bumper support member is first fixed to the body, and the upper portion of the bumper is fixed to the bumper support member. Next, the bracket is fixed to the bumper support member, the upper portion of the radiator grill is fixed to the body, and the lower portion is fixed to the bracket.

  However, in the above structure, the radiator grille is fixed directly to the body at the upper part, while the lower part is fixed to the body via a plurality of members such as a bracket and a bumper support member. For this reason, the position shift of the mounted portion tends to increase between the upper portion and the lower portion, which causes a decrease in the assembly workability of the radiator grill and variation in the mounting position.

  Moreover, since the bracket for exclusive use for attaching a radiator grille is provided, cost will increase.

  Further, if a gap or the like is generated between the radiator grille and the bumper due to variations in the mounting position of the radiator grille, the sense of unity in both appearances is impaired. Such inconvenience can be solved by integrally forming the radiator grille and the bumper. However, in this case, the molding die becomes large, resulting in an increase in cost.

  The present invention has been made in view of the above-mentioned problems, can suppress the displacement of the attached portion when the radiator grille is assembled, and can obtain a sense of unity in appearance between the radiator grille and the bumper. And it aims at provision of the vehicle front part structure which can reduce cost.

  In order to solve the above-described problems, a vehicle front structure according to the present invention includes a bumper support member fixed to the front surface of a vehicle body, a bumper fixed to the bumper support member, and a radiator grill disposed above the bumper. And comprising. The bumper has an opening, an upper part that defines the upper part of the opening, and a mounting hole formed in the upper part. The radiator grill has an upper part fixed to the body, a lower part covering a part of the opening, and a connecting part inserted through the attachment hole and fixed to the bumper support member.

  When assembling the bumper and the radiator grille, the bumper support member is first fixed to the body, and the bumper is fixed to the bumper support member. Next, the upper portion of the radiator grill is fixed to the body, and the connecting portion is inserted into the mounting hole of the bumper and fixed to the bumper support member. In this state, the lower portion of the radiator grill covers a part of the opening of the bumper.

  In the above configuration, the radiator grill is fixed at the upper part to the body and the lower part is fixed to the body via the bumper support member. That is, the member interposed between the lower portion of the radiator grill and the body is only the bumper support member. For this reason, it is possible to suppress the positional deviation of the mounted portion between the upper part and the lower part, and it is possible to improve the assembly workability of the radiator grill and reduce the variation in the mounting position.

  In addition, since a member such as a dedicated bracket for attaching the radiator grill is not required, the cost can be reduced.

  Further, since the lower part of the radiator grille covers a part of the bumper opening, it can be seen that the radiator grille and the opening are integrally formed. In other words, it is possible to give the radiator grille and the bumper a sense of unity in appearance while separating the radiator grille and the bumper from each other without causing an increase in cost due to the integral molding of the radiator grille and the bumper.

  Further, by setting the distance between the lower end of the radiator grille and the lower end of the bumper opening to be relatively large, even if an installation error occurs between the radiator grille and the bumper, the lower end of the radiator grille The variation in the distance from the lower end of the bumper opening is inconspicuous, and the appearance can be prevented from deteriorating due to mounting errors.
