Description

TECHNICAL FIELD The present invention relates to an antenna device and a cable withdrawal structure. BACKGROUND ART In recent years, various antenna devices have been developed. For example, an antenna device disclosed in Patent Document 1 includes a Global Positioning System (GPS) antenna, an Electronic Toll Collection System (ETC) antenna, a case, and a base member. The GPS antenna and the ETC antenna are accommodated in the case. A GPS cable is connected to the GPS antenna. An ETC cable is connected to the ETC antenna. Guide grooves for guiding the GPS cable and the ETC cable are provided on a lower surface of the base member. The guide grooves allow withdrawal of the GPS cable and the ETC cable in three directions of a rear side, a left side, and a right side of the case. RELATED DOCUMENT Patent Document Patent Document 1: Japanese Unexamined Patent Publication No. 2008-271270 SUMMARY OF THE INVENTION Technical Problem For example, the antenna device disclosed in Patent Document 1 has a structure to withdraw two cables of the GPS cable and the ETC cable in three directions on the same surface by the guide grooves. Accordingly, there is room for further improving the degree of freedom of the routing of the cable, for example, because of difficult routing for allowing the two cables to intersect. There is also room for further improving workability of the routing of the cables, for example, because of relatively complicated routing for inserting the two cables into the guide grooves. An example of an object of the present invention is to improve a degree of freedom and the workability of the routing of a cable. Other objects of the present invention will become apparent from the description of the present specification. Solution to Problem An aspect of the present invention is an antenna device including: a case;a first antenna accommodated in the case;a first antenna substrate provided with the first antenna; anda first cable connected to the first antenna substrate,in which each of a plurality of first side surfaces of the case is provided with a first insertion hole allowing withdrawal of the first cable, andthe first antenna substrate allows a withdrawal direction of the first cable to be changed with respect to the first insertion hole of each of the plurality of first side surfaces. An aspect of the present invention is a cable withdrawal structure to withdraw a first cable from a case, the first cable being connected to a first antenna substrate provided with a first antenna, the case accommodating the first antenna and the first antenna substrate, the cable withdrawal structure including: a first insertion hole provided in each of a plurality of first side surfaces of the case, the first insertion hole allowing withdrawal of the first cable; anda change portion provided on at least the first antenna substrate and allowing a withdrawal direction of the first cable to be changed with respect to the first insertion hole of each of the plurality of first side surfaces. According to the above aspects of the present invention, it is possible to improve a degree of freedom and the workability in routing a cable.
