[0032] Next, the radar cover 60 will be described.

[0033] As shown in FIG. 7, the radar cover 60 includes an upper engaged portion 61, a lower engaged portion 62, and a middle engaged portion 63.

[0034] The upper engaged portion 61 (an example of a second engaged portion in the present disclosure) is a portion that engages with the upper engaging portion 52 of the bracket 50. As shown in Fig. 7, the upper engaged portion 61 is provided on the tip side (upper end side in Fig. 7) of the radar cover 60 in the sliding direction (see arrow Ar2 in Fig. 7) in correspondence with the upper engaging portion 52 of the bracket 50. Specifically, as shown in the BB cross-sectional view in Fig. 6, the upper engaged portion 61 is an extension portion that extends upward from the tip side (upper end side in Fig. 6) of the radar cover 60 in the sliding direction.

[0035] The lower engaged portion 62 (an example of a third engaged portion in the present disclosure) is a portion with which the lower engaging portion 53 of the bracket 50 engages. As shown in FIG. 7, the lower engaged portion 62 is provided on the base end side (lower end side in FIG. 7) of the radar cover 60 in the sliding direction (see arrow Ar2 in FIG. 7) in correspondence with the lower engaging portion 53 of the bracket 50. As shown in the CC cross-sectional view in FIG. 6, the lower engaged portion 62 includes a first extension portion 62a extending rearward from the base end side (lower end side in FIG. 6) of the radar cover 60 in the sliding direction, and a second extension portion 62b extending upward from the tip end of the first extension portion 62a. A space S3 into which the lower engaging portion 53 of the bracket 50 is inserted is formed between the radar cover 60 and the second extension portion 62b (see CC cross-sectional view in FIG. 6).

[0036] The intermediate engaged portions 63 (an example of a first engaged portion of the present disclosure) are portions that engage with the hook portions 54 (intermediate engaged portions) of the bracket 50. As shown in Fig. 7, the intermediate engaged portions 63 are provided on both sides, above and below, of the radar cover 60 in the sliding direction (see arrows Ar2 in Fig. 7) in correspondence with the hook portions 54 of the bracket 50. Specifically, the intermediate engaged portions 63 are convex portions that engage with the hook portions 54 (concave portions 54b1) of the bracket 50 (see the DD cross-sectional view in Fig. 6).

[0037] The radar cover 60 configured as described above is detachably attached to the bracket 50. Specifically, first, as shown in Fig. 8, the radar cover 60 is disposed between the hook portions 54 of the brackets 50 on both the left and right sides with the back side of the radar cover 60 abutting against the front side of the bracket 50 (abutment surface 51a2; see Fig. 7) and with the intermediate engaged portions 63 of the radar cover 60 disposed below the hook portions 54 of the bracket 50. Fig. 8 is a perspective view of the state in which the back side of the radar cover 60 abuts against the front side of the bracket 50 and the intermediate engaged portions 63 of the radar cover 60 are disposed below the hook portions 54 of the bracket 50.

[0038] Next, the radar cover 60 positioned as described above is slid relative to the bracket 50 in the direction of arrow Ar2 in Figure 8, so that the upper engagement portion 52 of the bracket 50 engages with the upper engaged portion 61 of the radar cover 60 (see cross-sectional view BB in Figure 6), the lower engagement portion 53 of the bracket 50 engages with the lower engaged portion 62 of the radar cover 60 (see cross-sectional view CC in Figure 6), and the hook portion 54 of the bracket 50 engages with the intermediate engaged portion 63 (convex portion) of the radar cover 60 (see cross-sectional view DD in Figure 6).

[0039] Specifically, by the above-mentioned sliding movement, as shown in the BB cross-sectional view in FIG. 6, the upper engaged portion 61 (extension portion) of the radar cover 60 is inserted into the upper engaged portion 52 (space S2 between the bracket 50 (bracket main body 51) and the second extended portion 52b) of the bracket 50. This suppresses rattling of the radar cover 60 in the vehicle longitudinal direction. Also, by the above-mentioned sliding movement, as shown in the CC cross-sectional view in FIG. 6, the lower engaged portion 53 (extension portion) of the bracket 50 is inserted into the lower engaged portion 62 (space S3 between the radar cover 60 and the second extended portion 62b) of the radar cover 60. This also suppresses rattling of the radar cover 60 in the vehicle longitudinal direction. Also, by the above-mentioned sliding movement, as shown in the DD cross-sectional view in FIG. 6, the hook portion 54 (recess 54b1) of the bracket 50 is engaged with the intermediate engaged portion 63 (protrusion) of the radar cover 60. This allows the radar cover 60 to be detachably attached to the bracket 50 (at its fixed position).

[0040] The radar cover 60 slides in the direction of arrow Ar2 in Figure 8 along the hook portions 54 of the bracket 50 on both the left and right sides and the front side (abutment surface 51a2) of the bracket 50 relative to the bracket 50, guided by the hook portions 54 of the bracket 50 on both the left and right sides and the front side (abutment surface 51a2) of the bracket 50.

[0041] As described above, the engaging portions 52 to 54 of the bracket 50 engage with the engaged portions 61 to 63 of the radar cover 60, so that the radar cover 60 is detachably attached to the bracket 50 while being positioned relative to the bracket 50 in the up-down, front-rear, and left-right directions. 32c1 extends to the radar cover 60, whereas the front side (left side in FIG. 4) end E 32c2 extends to the bracket 50 (see FIG. 4). Therefore, the lower end of the radar cover 60 is not covered by the lower inner wall 32c2 and is exposed from the recess 32. This makes it possible to attach and detach the radar cover 60 to and from the bracket 50 attached to the outer lens 30 without removing the bracket 50 from the outer lens 30.

[0042] Next, the radar unit 70 will be described.

[0043] As shown in Fig. 5, the radar unit 70 (radar device) has a case 71, a transmitting antenna, and a receiving antenna (neither of which are shown) housed in the case 71. The radar unit 70 is a millimeter wave radar unit that transmits electromagnetic waves (millimeter waves) from the transmitting antenna. The electromagnetic waves (millimeter waves) pass through the radar cover 60 and spread at a vertical spread angle θ V (See Fig. 4), horizontal spread angle θ H(see FIG. 3). The radar unit 70 receives, by a receiving antenna, the reflected waves that are reflected by objects present within the transmission range and that pass through the radar cover 60. The received signals are processed by a control device, for example, an ECU (Electronic Control Unit) (not shown), and the objects (distance, angle, and speed to the object) are detected. The radar unit 70 uses, for example, millimeter waves in the 76-81 GHz band, particularly millimeter waves in the 79 GHz band, but is not limited to this frequency band.

[0044] The radar system of the radar unit 70 may be any of a pulse system, a CW (Continuous Wave) system, or other systems. The antenna system of the radar unit 70 may be any of a mechanical scanning system, a beam switching system, a phased array system, a digital forming system, or other systems.

[0045] The radar unit 70 having the above configuration is detachably attached to the bracket 50 (bracket body 51). Specifically, as shown in Fig. 7, the radar unit 70 is attached to the bracket 50 (bracket body 51) by screwing the screws N1 inserted into the flange portions 72 (three locations) of the radar unit 70 into the screw bosses 51a1 of the radar unit attachment surface 51a of the bracket 50 with the rear surface of the radar unit 70 facing the radar unit attachment surface 51a of the bracket 50.

[0046] Next, a procedure for mounting the vehicle lamp 10 having the above-mentioned configuration on the vehicle body will be described.

[0047] First, the bracket 50 is attached to the outer lens 30 (recess 32). Specifically, the bracket 50 is detachably attached to the outer lens 30 (recess 32) by known fixing means (screws, hooks, etc.) with the back surface of the bracket 50 facing the bottom 32b of the recess 32.

[0048] Next, the vehicle lamp 10 to which the bracket 50 is attached as described above is attached to the vehicle body side by known fixing means (screws, etc.).

[0049] Next, the radar unit 70 is attached to the bracket 50. Specifically, the radar unit 70 is detachably attached to the bracket 50 (bracket body 51) by screwing the screws N1 inserted into the flange portions 72 (three locations) of the radar unit 70 into the screw bosses 51a1 of the radar unit attachment surface 51a of the bracket 50 with the rear surface of the radar unit 70 facing the radar unit attachment surface 51a of the bracket 50.

[0050] Next, the radar cover 60 is attached to the bracket 50. Specifically, first, as shown in Fig. 8, the rear side of the radar cover 60 is abutted against the front side of the bracket 50 (abutment surface 51a2; see Fig. 7) and the intermediate engaged portions 63 of the radar cover 60 are disposed below the hook portions 54 of the bracket 50, and the radar cover 60 is disposed between the hook portions 54 of the bracket 50 on both the left and right sides.

[0051] Next, the radar cover 60 positioned as described above is slid relative to the bracket 50 in the direction of arrow Ar2 in Figure 8, so that the upper engagement portion 52 of the bracket 50 engages with the upper engaged portion 61 of the radar cover 60 (see cross-sectional view BB in Figure 6), the lower engagement portion 53 of the bracket 50 engages with the lower engaged portion 62 of the radar cover 60 (see cross-sectional view CC in Figure 6), and the hook portion 54 of the bracket 50 engages with the intermediate engaged portion 63 (convex portion) of the radar cover 60 (see cross-sectional view DD in Figure 6).

[0052] At that time, the radar cover 60 slides in the direction of arrow Ar2 in Figure 8 along the hook portions 54 of the bracket 50 on both the left and right sides and the front side (abutment surface 51a2) of the bracket 50 relative to the bracket 50, guided by the hook portions 54 of the bracket 50 on both the left and right sides and the front side (abutment surface 51a2) of the bracket 50.

[0053] As described above, by engaging each of the engaging portions 52-54 of the bracket 50 with each of the engaged portions 61-63 of the radar cover 60, the radar cover 60 is removably attached to the bracket 50 while being positioned relative to the bracket 50 in the up-down, front-back, and left-right directions.

[0054] Next, the bumper 90 is attached to the vehicle body. Specifically, as shown in Fig. 1 and Fig. 4, the bumper 90 is detachably attached to the vehicle body by known fixing means (screws or the like) in a state where the bumper 90 covers the radar cover 60 below the lower end portion thereof.

[0055] In this manner, the vehicle lamp 10 is attached to the vehicle body.

[0056] Next, a procedure for removing the radar unit 70 from the bracket 50 will be described. This procedure is performed, for example, when replacing the radar unit 70 in the event of a malfunction of the radar unit 70, or when rewriting the control program stored in a storage unit such as a ROM built into the radar unit 70 (for example, when upgrading the version).

[0057] First, the bumper 90 is removed from the vehicle body.

[0058] Next, the radar cover 60 is removed from the bracket 50.

[0059] Specifically, the radar cover 60 is slid relative to the bracket 50 in the direction of the arrow Ar3 in Fig. 4 to release the engagement of the upper engaging portions 52 of the bracket 50 with the upper engaged portions 61 of the radar cover 60 (see the BB cross section in Fig. 6), the engagement of the lower engaging portions 53 of the bracket 50 with the lower engaged portions 62 of the radar cover 60 (see the CC cross section in Fig. 6), and the engagement of the hook portions 54 of the bracket 50 with the intermediate engaged portions 63 (convex portions) of the radar cover 60 (see the DD cross section in Fig. 6). At this time, the radar cover 60 is guided by the hook portions 54 of the brackets 50 on both the left and right sides and slides relative to the bracket 50 in the direction of the arrow Ar3 in Fig. 4 along the hook portions 54 of the brackets 50 on both the left and right sides.

[0060] In this manner, the radar cover 60 can be removed from the bracket 50.

[0061] Next, the radar unit 70 is removed from the bracket 50 by removing the screw N1 that is exposed by removing the radar cover 60.

[0062] In this manner, the radar unit 70 can be removed from the bracket 50.

[0063] As described above, according to this embodiment, it is possible to provide a radar cover attachment / detachment structure that allows the radar cover 60 to be detachably attached to the bracket 50 by sliding the radar cover 60 in one direction (see arrow Ar2 in FIG. 8) relative to the bracket 50. Moreover, according to this embodiment, it is possible to attach and detach the radar cover 60 without using tools. Moreover, according to this embodiment, since no tools are used when attaching and detaching the radar cover 60, it is possible to prevent the tools from coming into contact with the surroundings (e.g., the outer lens 30, the bumper 90) and being damaged. Moreover, according to this embodiment, it is possible to reduce variation between workers when attaching and detaching the radar cover 60.

[0064] Next, a modified example will be described.
