It protrudes. The coaxial cables 16 </ b> A and 16 </ b> B are drawn out through the inside of the protruding wall portion 32, that is, between the wall portions 33 and 34. As shown in FIGS. 3, 12, 16, 18, 21, and the like, the convex portion 21 and the protruding wall portions 31 and 32 are portions that are fitted into the mounting holes 51 of the vehicle body roof 50 from above (inserted portions). The temporary fixing claws 31a, 33a, and 34a formed on the protruding wall portions 31 and 32 are engaged with the lower surface of the mounting hole 51 of the vehicle body roof 50 to perform a temporary fixing function.

  As shown in FIGS. 4 to 10 and the like, the conductor metal antenna mounting component 60 is opposed to a substantially rectangular mounting base 61 having a mounting through hole 62 in the center with respect to the antenna base 10 with the mounting through hole 62 interposed therebetween. And a pair of (first and second) locking mechanisms 70 respectively rising from two long sides (outer edge portions in the longitudinal direction) of the mounting base portion 61 to be mounted. The pair of locking mechanisms 70 are formed symmetrically with respect to a plane that passes through the center line between the two long sides of the mounting base 61 and is perpendicular to the mounting base 61. It has an opening arm portion 71 that can be brought into contact with the base side end surface 22a of the concave groove 22 at the tip edge, and a locking claw portion 80 for contact with the vehicle body roof 50 on which the antenna base 10 is placed. Each locking mechanism 70 is formed over substantially the entire length of the long side.

  The opening arm 71 rises from the vicinity of the center of the long side of the attachment base 61. At the tip of the opening arm 71, there is a tip that fits into the locking groove 22 formed along the longitudinal direction of the protrusion 21, and the width of the tip is larger than the width of the locking groove 22. Is also formed with a slightly shorter width. When the conductor metal antenna mounting component 60 is pressed against the convex portion 21 side of the antenna base 10 by tightening the conductor metal bolt 18, the distal end portion of the opening arm portion 71 is fitted into the locking groove 22. The leading edge abuts on the base end surface 22a. The opening arm portion 71 has a substantially rectangular hole 72 having a longitudinal direction in the vertical direction from the tip portion toward the mounting base portion 61, and is pressed against the antenna base 10 side by tightening the conductor metal bolt 18. Easy to bend. Further, on both sides of the opening hole 72 of the opening arm portion 71, a bending groove for reducing the thickness is formed on the inner surface side, and the first joint portion 73 is provided on the mounting base 61 side, and further, the meat is formed on the outer surface side. The bending direction is defined by forming a bending groove for reducing the thickness and providing the second joint portion 74 on the distal end side. More specifically, when the conductor metal antenna mounting component 60 is pressed against the convex portion 21 side of the antenna base 10 by tightening the conductor metal bolt 18, the opening arm portion 71 has the first joint portion 73 and the second joint portion. In the part 74, it bend | folds to the surface side which forms the groove | channel for bending, respectively. The locking claw portions 80 are provided on both sides of the opening arm portion 71, and the proximal end sides of the opening arm portion 71 and the locking claw portion 80 are connected by the connecting base portion 79. When the joint 73 is bent so as to protrude outward, the connecting base 79 and the locking claw 80 integrated with the base open to the outside. Note that the width of the long side and the short side of the mounting base 61 is larger than the width of the head of the conductor metal bolt 18 or the diameter of the circumscribed circle.

  The locking claws 80 are respectively provided at both ends of the locking mechanism 70 that are located on both sides of the opening arm 71. In other words, the latching claw portion 80 is positioned near the corner of the mounting base 61 when viewed from a direction perpendicular to the substantially rectangular mounting base 61. As shown in FIG. 6, the locking claw portion 80 in each locking mechanism 70 has a vertex 82 at the tip edge 81, and the positional relationship in which the vertexes 82 are separated from each other, that is, away from both sides of the locking mechanism 70. The leading edge 81 is inclined so as to be in a positional relationship. As shown in FIG. 21, the apex 82 of each locking claw portion 80 (which becomes a contact portion with the vehicle body roof 50) is attached in the state of being in contact with the vehicle body roof 50 as viewed from the direction perpendicular to the attachment base 61. It is at a position farthest from the through hole 62 for use or in the vicinity of the position. Each latching claw portion 80 is formed with a rib 88 protruding inward by press working or the like for reinforcement (so as not to bend).

  A locking mechanism is not provided on two sides (short sides: outer edges in the short direction) different from the two sides (long sides) on which the pair of locking mechanisms 70 of the mounting base 61 rises. In addition, the reinforcing rib 63 is formed over the entire length of each short side. The reinforcing rib 63 is formed with a small radius of curvature toward the top of the mounting base 61 (the same as the direction in which the locking mechanism 70 rises), and prevents the mounting base 61 from bending. The coaxial cables 16 </ b> A and 16 </ b> B are drawn inside the vehicle body roof 50 through the outside of the outer edge portion on the rear side (short side) of the mounting base 61.

  When the conductor metal antenna mounting component 60 is pressed against the convex portion 21 side of the antenna base 10 by tightening the conductor metal bolt 18, the pair of attachment bases 61 and the connection bases are provided so that the pair of locking mechanisms 70 can be easily opened. A through-hole 64 is formed at the boundary with 79. The through hole 64 is formed at a position near the center in the width direction of the opening arm portion 71 and a position directly below the apex 82 of the locking claw portion 80. In the first embodiment, one through-hole 64 is formed between the center in the width direction of the opening arm 71 and each vertex 82 on both sides of the opening arm 71.

  Next, a procedure for mounting and fixing the antenna device 1 according to Embodiment 1 of the present invention on the vehicle body roof 50 will be described.

  First, as shown in FIG. 11, a conductor metal antenna mounting part 60 is placed on the convex portion 21 which is a conductor metal portion of the antenna base 10 provided with an antenna and covered with the case 15, and the conductor metal bolt 18 is attached to the conductor metal bolt 18 in FIG. And loosely screwed into the female screw 26 (shown in FIG. 2 and the like) on the convex portion 21 side through the mounting through hole 62 of the conductor metal antenna mounting component 60 shown in FIG. Threaded). That is, the conductor metal antenna mounting part 60 and the conductor metal bolt 18 are integrally provided in advance on the antenna base 10 side.

  Next, as shown in FIGS. 3, 12, 14, 16, 18, and 20, the convex portion 21 and the projecting wall portions 31 and 32 of the antenna base 10 covered with the conductor metal antenna mounting component 60 are provided. Is fitted into the mounting hole 51 of the vehicle body roof 50. As shown in FIG. 20, the mounting hole 51 is formed in a substantially rectangular shape when viewed from the lower side of the vehicle body roof 50, and includes a protruding wall portion 31 disposed on the front side of the resin base portion 21 and a protruding wall portion disposed on the rear side. 32 and the conductor metal antenna attachment component 60 are configured so that the outer shape in plan view is slightly smaller than the attachment hole 51, so that the protruding wall portions 31, 32 and the conductor metal antenna attachment component 60 are attached to the attachment hole 51. Can pass through. Then, the temporary fixing claws 31 a, 33 a, 34 a provided on the projecting wall portions 31, 32 open after passing through the mounting hole 51, engage with the peripheral edge of the mounting hole 51, and the antenna base 10 is detached from the vehicle body roof 50. To prevent. At this time, rubber packings 17 and 18 provided on the bottom surface of the antenna base 10 shown in FIGS. 2 and 11 are interposed between the bottom surface of the antenna base 10 and the vehicle body roof 50.

  When the conductor metal bolt 18 is tightened from this state, the tip end edge of the opening arm portion 71 abuts on the base side end surface 22a of the locking groove 22 and the conductor metal antenna mounting component 60 moves in the rotational direction. And the upward movement are restricted, so that a force in the compression direction acts on the opening arm 71. As a result, as shown in FIG. 15, since the distal end portion of the opening arm portion 71 is fitted in the locking groove 22, the second joint portion 74 of the opening arm portion 71 forms a bending groove. The first joint portion 73 is moved to the outside of the mounting hole 51 and the first joint portion 73 is also bent to the surface side where the bending groove is formed. At this time, the connecting base portion 79 of the opening arm portion 71 is widened so that an angle formed with the mounting base portion 61 is increased with a side that is a boundary portion with the mounting base portion 61 as an axis, and the mounting hole 51 of the first joint portion 73 is formed. Follow the movement of the outside. Since the base end sides of the opening arm 71 and the locking claw 80 are connected by a connecting base 79, the connecting base 79 and the base are integrated when the first joint 73 moves outside the mounting hole 51. The locking claw portion 80 is opened outward, and the leading edge of the locking claw portion 80 faces the peripheral edge portion of the mounting hole 51. By further tightening of the conductor metal bolt 18, the deformation of the first and second joint portions 73 and 74 proceeds, the locking claw portion 80 is further expanded, and the sharp apex 82 abuts against the back surface of the vehicle body roof 50, Furthermore, it breaks into the painted surface and bites into the metal. Eventually, the conductor metal antenna mounting component 60 is sandwiched between the lower end surface of the convex portion 21 of the antenna base 10 and the head of the conductor metal bolt 18, and the conductor metal bolt 18 cannot be further tightened. It will be in a state and will be in the attachment completion state of the antenna apparatus 1 shown in FIG.13, FIG.15, FIG.17, FIG.19 and FIG. In the mounting completion state of the antenna device 1, the metal base portion 20 to which the ground of the antenna substrate 43 is electrically connected includes the convex portion 21, the conductor metal bolt 18, the conductor metal antenna mounting component 60, and the locking claw portion. The vehicle is electrically connected to the vehicle body roof 50 through 80 routes.

  According to the present embodiment, the following effects can be achieved.

(1) A conductor metal antenna mounting component 60 used for mounting the antenna device 1 to the vehicle body roof 50 (attached body) includes a mounting base 61 having a mounting through hole 62 for the antenna base 10, and a mounting through hole 62. And a pair of (first and second) locking mechanisms 70 that rise from the first and second outer edge portions of the mounting base 61 facing each other. However, since the locking mechanism for the antenna base 10 does not rise from the third and fourth outer edges that connect the first and second outer edges of the mounting base 61 to each other, there is no locking mechanism. 3. A plurality of cables can be pulled out from the antenna base 10 through the vehicle body roof 50 using one or both lateral spaces of the fourth and fourth outer edges.

(2) Each of the locking mechanisms 70 of the conductor metal antenna mounting component 60 includes an opening arm portion 71 that can contact the antenna base 10 at the tip edge, and a vehicle body roof 50 on which the antenna base 10 is placed. And a latching claw portion 80 for contact, and the antenna base 10 can be fitted into the mounting hole 51 of the vehicle body roof 50 with the conductor metal antenna mounting part 60 and the conductor metal bolt 18 provided in advance. Is possible. Then, by tightening the conductor metal bolt 18 after fitting, the latching claw portion 80 can be opened so as to face the peripheral edge portion of the mounting hole 51 by utilizing the deformation of the opening arm portion 71, and further made of conductor metal. By tightening the bolts 18, the locking claws 80 can be made to bite into the back surface of the vehicle body roof 50. For this reason, after the antenna base 10 is placed on the vehicle body roof 50, it is not necessary to attach the conductor metal antenna mounting component 60 with the conductor metal bolt 18 from the lower side of the vehicle body roof 50. Workability is good.

(3) In the pair of locking mechanisms 70, the locking claw portions 80 are provided at both end portions of the locking mechanism 70 at both sides of the opening arm portion 71. Thus, the vehicle body roof 50 is suppressed, and sufficient mounting strength can be secured.

(4) The locking claws 80 provided on both sides of the opening arm 71 have apexes 82 at the end edges 81, and the end edges 81 are inclined so that the apexes 82 are separated from each other. For this reason, the contact portion of the locking claw portion 80 with the vehicle body roof 50 is located at a position farthest from the mounting through-hole 62 or in the vicinity of the position when viewed from the direction perpendicular to the mounting base 61. In this respect as well, the mounting strength can be increased.

(5) Since the locking mechanisms 70 rise from the long sides of the mounting base 61 that face each other, the interval between the locking claws 80 can be increased, and the mounting strength can be improved in this respect as well.

(6) Since the reinforcing rib 63 is formed over the entire length of the third and fourth outer edge portions (a pair of short sides) where the locking mechanism of the mounting base portion 61 is not raised, the bending of the mounting base portion 61 can be prevented. In addition, it is possible to prevent a mounting failure due to the bending of the mounting base 61.

(7) Each of the locking mechanisms 70 is connected by a connecting base 79 that connects the base end sides of the opening arm 71 and the locking claw 80, and a boundary portion between the mounting base 61 and the connecting base 79. Since the through hole 64 is formed at an appropriate position, the locking mechanism 70 can be smoothly opened by the tightening operation of the conductor metal bolt 18.

(8) The convex portion 21 and the protruding wall portions 31 and 32 provided on the antenna base 10 are portions (inserted portions) that are fitted into the mounting holes 51 of the vehicle body roof 50 from above, and the protruding wall portions 31 and 32. By providing the temporary fixing claws 31a, 33a, and 34a respectively, the antenna base 10 can be temporarily fixed to the vehicle body roof 50, and the mounting workability of the antenna device 1 can be improved.

Embodiment 2
FIG. 22 shows a conductor metal antenna mounting component 60A according to Embodiment 2 of the present invention. In this case, of the pair of locking mechanisms, the locking claw portion 80A of one locking mechanism 70A is greatly different from the first embodiment in that the tip edge 81A has a rounded curved shape. Other configurations are substantially the same as those of the first embodiment.

  With such a configuration, the locking claw portion 80A of one locking mechanism 70A abuts without breaking the painted surface on the back surface of the vehicle body roof 50. In the first embodiment, all the locking claws are configured to break the painted surface of the vehicle roof and come into contact with the bare metal. However, as in the second embodiment, the locking claws of one locking mechanism. Even if the 80A is simply configured to abut on the painted surface of the vehicle roof, the effect similar to that of the first embodiment can be obtained.

Embodiment 3
FIG. 23 shows a conductor metal antenna mounting part 60B according to Embodiment 3 of the present invention. In this case, the tip edge 81B of the locking claw portion 80B of one locking mechanism 70B has a flat shape with no inclination instead of the tip edge 81A having a round and curved shape in the second embodiment. Other configurations are the same as those of the second embodiment. As a result, as in the second embodiment, the leading edge 80B abuts without breaking the painted surface on the back surface of the vehicle body roof 50, and has the same functions and effects as in the second embodiment.

  In the second and third embodiments, the leading edges of the two locking claws are formed so as to contact the metal base of the vehicle roof 50, but the leading edge of at least one locking claw is the vehicle roof 50.
