When the case 300 covers the base member 400, the convex portion fits into the first notch 316. As a result, at least a portion of the second right side surface portion 410 is exposed from the first right side surface portion 310 through the first notch 316. Therefore, the height of the antenna device 10 in the third direction Z can be lowered compared to when the base member 400 is positioned below the bottom end of the case 300. Furthermore, when the case 300 covers the base member 400, the second right side surface portion 410 is provided on the same side surface as the first right side surface portion 310.

As a result, at least a portion of the second rear side surface portion 420 is exposed from the first rear side surface portion 320 through the second notch 326. Therefore, the height of the antenna device 10 in the third direction Z can be lowered compared to when the base member 400 is positioned below the bottom end of the case 300. Furthermore, when the case 300 covers the base member 400, the second rear side surface portion 420 is provided on the same side as the first rear side surface portion 320.

As a result, a convex portion having the second left side surface 430 as its tip surface is formed on the side surface of the base member 400 on the positive side in the second direction Y. When the case 300 covers the base member 400, the convex portion fits into the third notch 336. As a result, at least a portion of the second left side surface 430 is exposed from the first left side surface 330 through the third notch 336.

The third left insertion hole 432 communicates with one end of a fourth guide groove 448 (described later) that is connected to a branch portion 450 and the other end is opposite the other end. The third left insertion hole 432 is configured to allow the second cable 230 to be drawn out toward the left of the base member 400. In other words, the third left insertion hole 432 has a shape, size, etc. that are compatible with the shape, diameter, etc. of the second cable 230.
[0043] When the above-described protrusions are fitted into the respective cutouts, the ends of the protrusions on the side of the two first cables 130 are formed in an arc shape so as to match the shapes of the two first cables 130 that are drawn out from the respective insertion holes on the respective sides of the case 300. This allows the two first cables 130 to be stably fixed to the case.

The other end of the fourth guide groove 448 on the third left insertion hole 432 side communicates with the third left insertion hole 432. Note that the first guide groove 442, the second guide groove 444, the third guide groove 446, and the fourth guide groove 448 all have shapes, sizes, etc. that are adapted to the shape, diameter, etc. of the second cable 230 so that the second cable 230 can be fitted therein.
[0049] As shown in FIG. 1 , the bracket 500 is provided below the case 300 and the base member 400. The bracket 500 is made of, for example, a steel plate. Four through holes 502 are provided in the bracket 500 at four locations around the four corners of the base member 400. A screw 504 passes through each through hole 502 from below the bracket 500. As shown in FIG. 2 , four mounting holes 302 are provided in the case 300. The upper end of each of the four screws 504 is inserted into one of the four mounting holes 302. As will be described later with reference to FIG. 6 , the second cable 230 is guided from the first guide groove 442 to the second guide groove 444, the third guide groove 446, or the fourth guide groove 448, and is then drawn out from the third right insertion hole 412, the third rear insertion hole 422, or the third left insertion hole 432. The bracket 500 is attached to the case 300 in a state in which the second cable 230 is guided from the first guide groove 442 to the second guide groove 444, the third guide groove 446, or the fourth guide groove 448, and is pulled out from the third right insertion hole 412, the third rear insertion hole 422, or the third left insertion hole 432. Therefore, the bracket 500 can prevent the second cable 230 from slipping out of the first guide groove 442, the second guide groove 444, the third guide groove 446, and the fourth guide groove 448 downwardly of the base member 400.
[0050] Fig. 3 is a diagram illustrating a method for drawing two first cables 130 out from the first right side surface portion 310 in the cable lead-out structure according to the embodiment. Fig. 4 is a diagram illustrating a method for drawing two first cables 130 out from the first rear side surface portion 320 in the cable lead-out structure according to the embodiment. Fig. 5 is a diagram illustrating a method for drawing two first cables 130 out from the first left side surface portion 330 in the cable lead-out structure according to the embodiment.
[0051] In Figures 3 to 5, the white circle with an X indicating the third direction Z indicates that the direction from the front of the paper to the back is the positive direction of the third direction Z, and the direction from the back of the paper to the front is the negative direction of the third direction Z.
[0052] As shown in FIGS. 3 to 5, a first protrusion 304a and a second protrusion 304b are provided inside the case 300. The first protrusion 304a and the second protrusion 304b protrude from the positive side of the third direction Z of the case 300 toward the negative side of the third direction Z. The first protrusion 304a is located on the negative side of the second direction Y with respect to the center of the case 300 in the second direction Y. The second protrusion 304b is located on the positive side of the second direction Y with respect to the center of the case 300 in the second direction Y. The position of the second protrusion 304b in the first direction X is located on the negative side of the first direction X with respect to the position of the first protrusion 304a in the first direction X. In other words, in a projection of the first protrusion 304a and the second protrusion 304b parallel to the second direction Y onto an imaginary plane perpendicular to the second direction Y, the second protrusion 304b is located on the negative side of the first direction X with respect to the first protrusion 304a.
[0053] 3 , when the two first cables 130 are pulled out from the first right side surface portion 310, the first protrusion 304a of the case 300 is inserted through the first hole 112a of the first antenna board 110, and the second protrusion 304b of the case 300 is inserted through the second hole 112b of the first antenna board 110. This allows the first antenna board 110 to be attached to the case 300 with the first side 110a of the first antenna board 110 facing the side of the case 300 where the first right side surface portion 310 is located. Therefore, the first GNSS cable 132 can be pulled out from the first right insertion hole 312. Furthermore, the second GNSS cable 134 can be pulled out from the second right insertion hole 314.
[0054] 3, the first protrusion 304a and the second protrusion 304b are inserted into the first hole 112a and the second hole 112b, which are two holes located at diagonal corners of the first antenna substrate 110. Therefore, the first antenna substrate 110 can be attached to the case 300 more stably than when the first protrusion 304a and the second protrusion 304b are inserted into two holes located at two adjacent corners of the first antenna substrate 110.
[0055] 4 , when the two first cables 130 are drawn out from the first rear side surface portion 320, the first protrusion 304a of the case 300 is inserted through the third hole 112c of the first antenna board 110, and the second protrusion 304b of the case 300 is inserted through the fourth hole 112d of the first antenna board 110. This allows the first antenna board 110 to be attached to the case 300 with the first side 110a of the first antenna board 110 facing the side of the case 300 where the first rear side surface portion 320 is located. Therefore, the first GNSS cable 132 can be drawn out from the first rear insertion hole 322. The second GNSS cable 134 can be drawn out from the second rear insertion hole 324.
[0056] 4, the first protrusion 304a and the second protrusion 304b are inserted into the third hole 112c and the fourth hole 112d, which are two holes located at diagonal corners of the first antenna substrate 110. Therefore, the first antenna substrate 110 can be attached to the case 300 more stably than when the first protrusion 304a and the second protrusion 304b are inserted into two holes located at two adjacent corners of the first antenna substrate 110.
[0057] 5 , when the two first cables 130 are pulled out from the first left side surface portion 330, the first protrusion 304a of the case 300 is inserted through the second hole 112b of the first antenna board 110, and the second protrusion 304b of the case 300 is inserted through the first hole 112a of the first antenna board 110. This allows the first antenna board 110 to be attached to the case 300 with the first edge 110a of the first antenna board 110 facing the side of the case 300 where the first left side surface portion 330 is located. Therefore, the first GNSS cable 132 can be pulled out from the first left insertion hole 332. Furthermore, the second GNSS cable 134 can be pulled out from the second left insertion hole 334.
[0058] 5, the first protrusion 304a and the second protrusion 304b are inserted into the second hole 112b and the first hole 112a, respectively, which are two holes located at diagonal corners of the first antenna substrate 110. Therefore, the first antenna substrate 110 can be attached to the case 300 more stably than when the first protrusion 304a and the second protrusion 304b are inserted into two holes located at two adjacent corners of the first antenna substrate 110.
[0059] The first hole 112a, the second hole 112b, the third hole 112c, and the fourth hole 112d of the first antenna board 110 and the first protrusion 304a and the second protrusion 304b of the case 300 have the function of positioning the two first cables 130 and the first right insertion hole 312 and the second right insertion hole 314, or the function of positioning the two first cables 130 and the first rear insertion hole 322 and the second rear insertion hole 324, or the function of positioning the two first cables and the first left insertion hole 332 and the second left insertion hole 334. In other words, by inserting each protrusion of the case 300 into each hole of the first antenna board 110, the two first cables 130 are positioned relative to each insertion hole. In this embodiment, the first hole 112a, the second hole 112b, the third hole 112c, and the fourth hole 112d of the first antenna substrate 110 function as change units that make it possible to change the direction in which the two first cables 130 are pulled out relative to each insertion hole. In addition, the first hole 112a, the second hole 112b, the third hole 112c, and the fourth hole 112d of the first antenna substrate 110 in this embodiment make it possible to change the direction in which the two first cables 130 are pulled out when the two first cables 130 are connected to the first antenna substrate 110.
[0060] 3 to 5 , in the cable lead-out structure according to this embodiment, the direction in which the two first cables 130 are led out can be changed to the right, rear, or left of the case 300 depending on whether the two first cables 130 are led out from the first right insertion hole 312 and the second right insertion hole 314, the first rear insertion hole 322 and the second rear insertion hole 324, or the first left insertion hole 332 and the second left insertion hole 334. Furthermore, whether the two first cables 130 are led out from any of the insertion holes in the multiple side surfaces of the case 300, including the first right side surface portion 310, the first rear side surface portion 320, and the first left side surface portion 330, can be changed by the first antenna board 110. Therefore, the direction in which the two first cables 130 are led out can be easily changed, improving the flexibility and workability of routing the two first cables 130.
[0061] Specifically, in the cable lead-out structure according to this embodiment, the first antenna board 110 has a shape that allows the first GNSS cable 132 and the second GNSS cable 134 to be attached to the first protrusion 304a and the second protrusion 304b in a state in which the first GNSS cable 132 and the second GNSS cable 134 are led out from the first right insertion hole 312 and the second right insertion hole 314, the first rear insertion hole 322 and the second rear insertion hole 324, or the first left insertion hole 332 and the second left insertion hole 334. Therefore, by changing the orientation of the first antenna board 110 relative to the case 300, the direction in which the two first cables 130 are led out can be changed to the right, rear, or left of the case 300.
[0062] 3 to 5, in the cable lead-out structure according to this embodiment, the two first cables 130 can be led out of the case 300 without passing through a guide groove provided in the underside of the base member 400. Therefore, it is not necessary to route the two first cables 130 and the second cable 230 on the same plane of the guide groove provided in the underside of the base member 400. Therefore, compared to the case where the two first cables 130 pass through a guide groove provided in the underside of the base member 400, it is possible to increase the variety of ways in which the two first cables 130 and the one second cable 230 can be routed.
[0063] 3 to 5, in the cable lead-out structure according to this embodiment, the two first cables 130 can be led out straight from the first antenna 120 from any of the first right insertion hole 312 and the second right insertion hole 314, the first rear insertion hole 322 and the second rear insertion hole 324, or the first left insertion hole 332 and the second left insertion hole 334. Therefore, it is possible to suppress fluctuations in the characteristics of the first antenna 120 caused by bending the two first cables 130.
[0064] The direction in which the two first cables 130 are pulled out is not limited to the right, rear, or left of the case 300. For example, the two first cables 130 may be pulled out in other directions, such as the front, upper, diagonally rear right, or diagonally front left of the case 300. The direction in which each first cable 130 is pulled out can be changed depending on the orientation of the side surface of the case 300 on which the insertion hole is provided and the orientation of the side of the first antenna board 110 from which each first cable 130 is pulled out when the first antenna board 110 is attached to the case 300.
[0065] The shape of the first antenna substrate 110 is not limited to the shape according to this embodiment. For example, the shape of the first antenna substrate 110 may be a shape that has rotational symmetry about the center of the first antenna substrate 110 when viewed from the third direction Z.
[0066] In one example, the shape of the first antenna substrate 110 may be a rectangle having a pair of long sides and a pair of short sides when viewed from the third direction Z. In this example, for example, the two first cables 130 are pulled out from one short side of the rectangle. In this case, the direction in which the two first cables 130 are pulled out can be changed by orienting the short side of the first antenna substrate 110 that is located on the side from which the two first cables 130 are pulled out.
[0067] As another example, the shape of first antenna substrate 110 may be a regular polygon such as an equilateral triangle, a regular pentagon, a regular hexagon, or a regular octagon when viewed from third direction Z. In this example, for example, two first cables 130 are pulled out from one side of the regular polygon. In this case, the direction in which the two first cables 130 are pulled out can be changed by orienting the side of first antenna substrate 110 from which the two first cables 130 are pulled out.
[0068] As yet another example, the shape of the first antenna substrate 110 may be a circle or an ellipse when viewed from the third direction Z. In this example, for example, the two first cables 130 are pulled out from any part of the circumference of the circle or ellipse. In this case, the direction in which the first cables 130 are pulled out can be changed by orienting the part of the first antenna substrate 110 on the side from which the two first cables 130 are pulled out.
[0069] Fig. 6 is a bottom view of the antenna device 10 in a state where two first cables 130 and one second cable 230 are drawn out from the first right side surface part 310. Fig. 7 is a right side view of the antenna device 10 in a state where two first cables 130 and one second cable 230 are drawn out from the first right side surface part 310. For the sake of explanation, the bracket 500 shown in Fig. 1 has been removed from Figs. 6 and 7.
[0070] In Fig. 6, the white circle with an X indicating the third direction Z indicates that the direction from the front of the paper to the back is the positive direction of the third direction Z, and the direction from the back of the paper to the front is the negative direction of the third direction Z. In Fig. 7, the white circle with an X indicating the second direction Y indicates that the direction from the front of the paper to the back is the positive direction of the second direction Y, and the direction from the back of the paper to the front is the negative direction of the second direction Y.
[0071] 6, a method for pulling out the second cable 230 from the third right insertion hole 412 will be described. The second cable 230 is pulled out from the third right insertion hole 412 from the upper surface side of the base member 400 via the fourth notch 402, the front insertion hole 452, the first guide groove 442, the branch portion 450, and the second guide groove 444, as follows.
[0072] The second cable 230 is folded back from the upper surface side of the base member 400, passing through the fourth notch 402, to the front insertion hole 452. In the present embodiment, the front insertion hole 452 is offset in the second direction Y with respect to a portion of the second cable 230 that is located on the upper surface side of the base member 400. Specifically, the portion of the second cable 230 that is located on the upper surface side of the base member 400 is located on the positive side of the second direction Y with respect to the center of the case 300 in the second direction Y. In contrast, the front insertion hole 452 is located on the negative side of the second direction Y with respect to the center of the case 300 in the second direction Y. Therefore, compared to a case in which the front insertion hole 452 is aligned in the second direction Y with the portion of the second cable 230 that is located on the upper surface side of the base member 400, the height difference of the second cable 230 in the third direction Z can be kept small.
[0073] The method of folding back the second cable 230 from the upper surface side of the base member 400 to the front insertion hole 452 is not limited to the method according to the present embodiment. For example, the front insertion hole 452 may be aligned in the second direction Y with a portion of the second cable 230 located on the upper surface side of the base member 400. For example, the front insertion hole 452 may be located at the center of the case 300 in the second direction Y. Furthermore, the portion of the second cable 230 located on the upper surface side of the base member 400 may be located at the center of the case 300 in the second direction Y.
[0074] The second cable 230 is guided by the first guide groove 442 from the front insertion hole 452 to the branching portion 450. In the present embodiment, the first guide groove 442 forms a meandering, curved path from the front insertion hole 452 to the branching portion 450. Therefore, the first guide groove 442 ensures a curvature for bending the second cable 230 from the front insertion hole 452 to the branching portion 450 located approximately at the center of the base member 400 in the second direction Y, improving the workability of routing the second cable 230.
[0075] In the present embodiment, the portion of the first guide groove 442 surrounding the branched portion 450 is curved from the positive direction in the second direction Y toward the negative direction in the first direction X to guide the second cable 230 from the first guide groove 442 to the second guide groove 444. Therefore, when the second cable 230 is pulled out from the third right insertion hole 412, the portion of the first guide groove 442 that is curved from the positive direction in the second direction Y toward the negative direction in the first direction X can easily guide the second cable 230 into the second guide groove 444, improving the workability of routing the second cable 230.
[0076] In this embodiment, a first stopper 442a is provided in a portion of the first guide groove 442. The first stopper 442a includes protrusions that protrude from both sides of the lower end of the opening of the first guide groove 442 toward the center of the opening. The provision of the first stopper 442a makes it more difficult for the second cable 230 to come out of the first guide groove 442 compared to a case in which the first stopper 442a is not provided. The first stopper 442a does not have to be provided.
[0077] The second cable 230 is guided from the branching portion 450 to the third right insertion hole 412 by the second guide groove 444. In the present embodiment, a portion of the second guide groove 444 surrounding the branching portion 450 is curved from the negative direction in the first direction X toward the negative direction in the second direction Y in order to guide the second cable 230 from the first guide groove 442 to the second guide groove 444. Therefore, when the second cable 230 is pulled out from the third right insertion hole 412, the second cable 230 can be easily guided into the second guide groove 444 by the portion of the second guide groove 444 that is curved from the negative direction in the first direction X toward the negative direction in the second direction Y, thereby improving the workability of routing the second cable 230.
[0078] In this embodiment, a second stopper 444a is provided in a part of the second guide groove 444, similar to the first stopper 442a of the first guide groove 442. The second stopper 444a does not necessarily have to be provided.
[0079] 6, a method for pulling out the second cable 230 from the third rear insertion hole 422 will be described. The method for pulling out the second cable 230 from the third rear insertion hole 422 is similar to the method for pulling out the second cable 230 from the third right insertion hole 412, except for the following points.
[0080] In a manner similar to the method for pulling out the second cable 230 from the third right insertion hole 412, the second cable 230 is folded back from the upper surface side of the base member 400 through the fourth notch 402 to the front insertion hole 452, and is guided by the first guide groove 442 from the front insertion hole 452 to the branching portion 450.
[0081] The second cable 230 is guided by the third guide groove 446 from the branching portion 450 to the third rear insertion hole 422. In the present embodiment, the third guide groove 446 extends in the first direction X from the branching portion 450 to the third rear insertion hole 422. Therefore, the second cable 230 can be pulled out straight from the branching portion 450 to the third rear insertion hole 422.
[0082] In this embodiment, a third stopper 446a is provided in a part of the third guide groove 446, similar to the first stopper 442a of the first guide groove 442. The third stopper 446a does not necessarily have to be provided.
[0083] 6, a method for pulling out the second cable 230 from the third left insertion hole 432 will be described. The method for pulling out the second cable 230 from the third left insertion hole 432 is similar to the method for pulling out the second cable 230 from the third right insertion hole 412, except for the following points.
[0084] In a manner similar to the method for pulling out the second cable 230 from the third right insertion hole 412, the second cable 230 is folded back from the upper surface side of the base member 400 through the fourth notch 402 to the front insertion hole 452, and is guided by the first guide groove 442 from the front insertion hole 452 to the branching portion 450.
[0085] The second cable 230 is guided by the fourth guide groove 448 from the branching portion 450 to the third left insertion hole 432. In the present embodiment, a portion of the fourth guide groove 448 surrounding the branching portion 450 is curved from the negative direction in the first direction X toward the positive direction in the second direction Y to guide the second cable 230 from the first guide groove 442 to the fourth guide groove 448. Therefore, when the second cable 230 is pulled out from the third left insertion hole 432, the second cable 230 can be easily guided into the fourth guide groove 448 by the portion of the fourth guide groove 448 that is curved from the negative direction in the first direction X to the positive direction in the second direction Y, improving the workability of routing the second cable 230.
[0086] In this embodiment, a fourth stopper 448a is provided in a part of the fourth guide groove 448, similar to the first stopper 442a of the first guide groove 442. The fourth stopper 448a does not necessarily have to be provided.
[0087] The direction in which the second cable 230 is pulled out is not limited to the right, rear, or left of the base member 400. For example, the second cable 230 may be pulled out in other directions, such as diagonally rear right or diagonally front left of the base member 400. The direction in which the second cable 230 is pulled out can be changed by the orientation of the side surface of the base member 400 on which the insertion hole is provided and the shape of the guide groove provided in the base member 400.
[0088] The arrangement of the two first cables 130 and one second cable 230 will be described with reference to Fig. 7. Hereinafter, in this embodiment, the height direction of the case 300 is a direction parallel to the third direction Z. Also, in this embodiment, the height of the case 300 in the height direction increases toward the positive direction of the third direction Z.
[0089] The first GNSS cable 132 and the second GNSS cable 134 are drawn out from the first right insertion hole 312 and the second right insertion hole 314, respectively, via an area on the upper surface of the base member 400. That is, in the cable drawing structure according to this embodiment, the two first cables 130 can be drawn out from either the first right insertion hole 312 and the second right insertion hole 314, the first rear insertion hole 322 and the second rear insertion hole 324, or the first left insertion hole 332 and the second left insertion hole 334, via an area on the opposite side of the base member 400 from where the first guide groove 442, the second guide groove 444, the third guide groove 446, and the fourth guide groove 448 are located.
[0090] In the cable guide structure according to the present embodiment, the height at which the first right insertion hole 312 and the second right insertion hole 314 are located in the height direction of the case 300 is different from the height at which the third right insertion hole 412 is located in the height direction of the case 300. Specifically, the height at which the first right insertion hole 312 and the second right insertion hole 314 are located in the height direction of the case 300 is higher than the height at which the third right insertion hole 412 is located in the height direction of the case 300. Similarly, as shown in FIG. 2 , the height at which the first rear insertion hole 322 and the second rear insertion hole 324 are located in the height direction of the case 300 is higher than the height at which the third rear insertion hole 422 is located in the height direction of the case 300. Furthermore, the height at which the first left insertion hole 332 and the second left insertion hole 334 are located in the height direction of the case 300 is higher than the height at which the third left insertion hole 432 is located in the height direction of the case 300.
[0091] In this embodiment, the area where each first cable 130 is routed and the area where each second cable 230 is routed can be shifted in the height direction of the case 300. Therefore, compared to a case where each first cable 130 and each second cable 230 are located at the same height in the height direction of the case 300, the degree of freedom in routing each first cable 130 and each second cable 230 can be improved.
[0092] In the present embodiment, each first cable 130 can be pulled out from the case 300 without passing through a guide groove provided in the base member 400. Therefore, compared to the case where both the first cable 130 and the second cable 230 are pulled out from the base member 400 through the guide groove, the degree of freedom and workability in routing the first cable 130 and the second cable 230 can be improved.
[0093] In the present embodiment, the first cables 130 and the second cables 230 can be routed in a state in which at least a portion of each first cable 130 and at least a portion of the second cable 230 overlap in the height direction of the case 300. Therefore, compared to when the first cables 130 and the second cables 230 are positioned at the same height in the height direction of the case 300, the footprints of the first cables 130 and the second cables 230 in the direction perpendicular to the height direction of the case 300 can be reduced. Therefore, in the present embodiment, compared to when the first cables 130 and the second cables 230 are positioned at the same height in the height direction of the case 300, an increase in the size of the case 300 in the direction perpendicular to the height direction of the case 300 can be reduced.
[0094] In the present embodiment, the third right through-hole 412 is located in a region of the case 300 that is at the same height as the third right through-hole 412 in the height direction of the case 300, but not in a region that overlaps with the first right through-hole 312 and the second right through-hole 314 in the height direction of the case 300. In other words, in a projection of the first right through-hole 312, the second right through-hole 314, and the third right through-hole 412 onto an imaginary plane perpendicular to the third direction Z, parallel to the third direction Z, the third right through-hole 412 does not overlap with the first right through-hole 312 and the second right through-hole 314. Furthermore, in the present embodiment, the third right through-hole 412 is located between the regions that overlap with the first right through-hole 312 and the second right through-hole 314 in the height direction of the case 300 in a region that is at the same height as the third right through-hole 412 in the height direction of the case 300. 2, the third rear through-hole 422 is located between the portions of the first rear through-hole 322 and the second rear through-hole 324 that overlap with the height of the case 300 in a region that is at the same height as the third rear through-hole 422 in the height direction of the case 300. Furthermore, the third left through-hole 432 is located between the portions of the first left through-hole 332 and the second left through-hole 334 that overlap with the height of the case 300 in a region that is at the same height as the third left through-hole 432 in the height direction of the case 300.
[0095] In this embodiment, the distance between the second cable 230 and each first cable 130 can be increased compared to when at least a portion of the third right insertion hole 412 overlaps with the first right insertion hole 312 or the second right insertion hole 314 in the height direction of the case 300. Therefore, compared to when at least a portion of the third right insertion hole 412 overlaps with at least a portion of the first right insertion hole 312 or the second right insertion hole 314 in the height direction of the case 300, the workability of routing the first cable 130 and the second cable 230 can be improved.
[0096] In this embodiment, the direction in which the two first cables 130 are pulled out and the direction in which the single second cable 230 is pulled out can be determined independently. For example, if the side surface of the case 300 having an insertion hole through which the first cables 130 are pulled out and the side surface of the base member 400 having an insertion hole through which the second cable 230 is pulled out are provided on the same side, the first cables 130 and the second cables 230 can be pulled out in the same direction. For example, by pulling the first GNSS cable 132 and the second GNSS cable 134 out of the first right insertion hole 312 and the second right insertion hole 314, respectively, and pulling the second cable 230 out of the third right insertion hole 412, the first GNSS cable 132, the second GNSS cable 134, and the second cable 230 can all be pulled out to the right of the antenna device 10. Furthermore, if the side surface of the case 300 having the insertion hole through which the first cable 130 is pulled out and the side surface of the base member 400 having the insertion hole through which the second cable 230 is pulled out are provided on different sides, the first cable 130 and the second cable 230 can be pulled out in different directions. For example, by pulling the first GNSS cable 132 and the second GNSS cable 134 out of the first right insertion hole 312 and the second right insertion hole 314, respectively, and pulling the second cable 230 out of the third left insertion hole 432, the first GNSS cable 132 and the second GNSS cable 134 can be pulled out to the right of the antenna device 10, and the second cable 230 can be pulled out to the left of the antenna device 10.

However, even if the first antenna 120 is different from a GNSS antenna, the cable lead-out structure according to this embodiment is applicable in the same way as when the first antenna 120 is a GNSS antenna. Furthermore, in this embodiment, the second antenna 220 is an ETC antenna. However, even if the second antenna 220 is different from an ETC antenna, the cable lead-out structure according to this embodiment is applicable in the same way as when the second antenna 220 is an ETC antenna.
[0099] Furthermore, in this embodiment, two first cables 130 are connected to the first antenna 120. However, even if the number of first cables 130 connected to the first antenna 120 is only one or three or more, the cable lead-out structure according to this embodiment is applicable in the same way as when two first cables 130 are connected to the first antenna 120. Furthermore, in this embodiment, one second cable 230 is connected to the second antenna 220. However, even if the number of second cables 230 connected to the second antenna 220 is two or more, the cable lead-out structure according to this embodiment is applicable in the same way as when one second cable 230 is connected to the second antenna 220.
