As shown in FIG. 2, the front bumper 10 has an opening formed on the rear surface 11, which is the inner wall of the engine compartment, and the front grille 20 closes the opening. Around the opening of the front bumper 10, a frame 12 extending rearward in the longitudinal direction of the vehicle and substantially perpendicular to the rear surface 11 is provided integrally with the rear surface 11. The front grille 20 is formed on the frame 12. located inside.

A restricting portion 13 is provided on the edge of the frame 12 of the front bumper 10 and protrudes toward the center of the opening to restrict movement of the front grille 20 rearward in the vehicle length direction toward the engine compartment. The bottom surface of the restricting portion 13 forms a connecting surface 13a having slits 13x into which connecting projections 24 and 25 of the front grille 20, which will be described later, are inserted.

The front grille 20 includes a plurality of crosspieces 21 extending in the vehicle width direction and arranged in the vehicle height direction so as to form a gap A for communicating the engine compartment of the vehicle 1 with the outside. A plurality of plate portions 22 and 23 located at both ends of the portion 21 and connecting them are integrally formed. Connecting protrusions 24 and 25 extending rearward in the vehicle length direction are integrally formed on a part of the plate portion 22 and on the surface of the plate portion 23, respectively, and are used to connect the front bumper 10 as shown in FIG. It is fitted into a slit 13x formed in the surface 13a.

The plate portion 23 has a dimension along the vehicle width direction larger than that of the plate portion 22, and a front sonar 50 as an electrical component is arranged on the surface thereof. The wire harness 30 connected to the front sonar 50 is held by the clamp 40 fixed to the connecting projection 25, so that the wire harness 30 bypasses the restricting portion 13 of the front bumper 10 from the plate portion 23 and extends from the frame 12 to the rear surface 11. It is routed along the surface. Details of how the wire harness 30 is held by the clamp 40 will be described later.

As shown in FIG. 25 is a portion inserted into an opening 25x opened at the tip of 25. As shown in FIG.

The claw portion 43a of the latch 43 is deformed in a closing direction while the latch 43 is inserted into the opening 25x, and restores its open shape after passing through the opening 25x. As a result, the latch 43 engages the connecting projection 25 to couple the clamp 40 and the front grill 20 together. A pair of wall portions 41c are provided on both sides of the latch 43 to prevent direct interference between the latch 43 and the connecting projection 25 and the wire harness 30, as shown in FIG. Further, a mounting portion 45 having a through hole 45x is provided on the rear surface 41b of the main surface 41a on which the latch 43 is provided, and as shown in FIG. A binding band 60 is attached.

As shown in FIGS. 4A and 5B, the guide portion 42 has a side surface shape in which a main surface 42a is bent in a substantially L shape, and from the side facing the latch 43 in the body portion 41, This is the extended part.
