- the guide surface (40) of the guide member (43) is provided with five circumferentially extending grooves (49) which are spaced apart in the axial direction. It is recessed.
- the guide member (43) is smaller than the diameter of the coaxial cable (22) between the guide surface (40) of the guide member (43) and the outer peripheral surface of the shaft member (24). spacing S 2 Oa only with, rotatably mounted on a pair of arcuate piece portion (44) (44).
- the five coaxial cables (22) exposed from the upper cabinet (2) are fitted in the grooves (49) of the guide surface (40), and are fitted to the guide surface (40) of the guide member (43) and the shaft member (24). ), So that the coaxial cables (22) are arranged neatly at regular intervals on the guide surface (40).
- the coaxial cable (22) passes between the guide surface (40) of the guide member (43) and the outer peripheral surface of the shaft member (24) while maintaining a constant distance from each other, and the lower cabinet (4) Extending towards.
- the guide surface (40) of the guide member (43) and the shaft member (24) are fitted with the five coaxial cables (22) fitted in the grooves (49) of the guide surface (40). ) Are sandwiched between the surfaces, since natural even spacing S 2 between the guide surface (40) and the shaft member (24) is smaller than the diameter of the coax one pull (22), coaxial cable (22) Is bound inside the groove (49). Therefore, the five coaxial cables (22) do not come out of the groove (49) with the opening and closing operations of both cabinets (2) and (4), and do not become entangled with each other.
- the antenna device of the present embodiment shown in FIGS. 14 and 15 has a structure in which five coaxial cables (22) pass through the hinge mechanism (3) connecting the two cabinets (2) and (4).
- the structure held between the outer peripheral surface of the shaft member (24) protruding from the cabinet (2) and the guide surface (40) of the guide member (43) mounted on the lower cabinet (4) It has the same structure as the first embodiment, but as shown in FIG. 14, on the outer peripheral surface of the shaft member (24), five winding grooves (25) extending in the circumferential direction are arranged at intervals in the axial direction. And is recessed. Further, as shown in FIG.
- the guide member (43) is larger than the diameter of the coaxial cable (22) between the guide surface (40) of the guide member (43) and the outer peripheral surface of the shaft member (24). small spacing S 3 Oa only by, rotatably mounted on a pair of arcuate piece portion (44) (44).
- the five coaxial cables (22) exposed from the upper cabinet (2) are fitted in the winding groove (25) of the shaft member (24) and the guide surface (40) of the guide member (43) and the shaft member.
- the coaxial cable (22) is arranged at regular intervals on the outer peripheral surface of the shaft member (24). Then, the coaxial cable (22) passes between the guide surface (40) of the guide member (43) and the outer peripheral surface of the shaft member (24) while maintaining a constant interval, and the lower cabinet (4) Extending towards.
- the guide surface (40) of the guide member (43) and the shaft (24) are fitted with the five coaxial cables (22) in the-winding grooves (25) of the shaft member (24). It is held between the outer peripheral surfaces of the member (24), and the distance S 3 between the guide surface (40) and the shaft member (24) is smaller than the diameter of the coaxial cable (22).
- the coaxial cable (22) is restrained inside the winding groove (25). Therefore, with the opening and closing operation of both cabinets (2) and (4), 5 The coaxial cables (22) do not come out of the grooves (49) and do not become entangled with each other.
- the wireless module (41) is built in the main body (1) of the television receiver, and the upper cabinet (2) is connected to the main body (1) so as to be openable and closable. by construction, c where ⁇ results similar to the above embodiment can be obtained
- a guide surface (40) is formed on the inner surface of the opening (48) of the lower cabinet (4), and the guide surface (40) is formed. 40), five grooves (49) are recessed, and the outer peripheral surfaces of the guide surface (40) and the shaft member (24) with the coaxial cable (22) fitted in the grooves (49). The same effect as in the above embodiment can be obtained by the configuration in which the coaxial cable (22) is held between the two.
- the same structure as in the above embodiment can be obtained by incorporating the wireless module (41) into the main body (1) of the television receiver and connecting the upper cabinet (2) to the main body (1) so as to be openable and closable. The effect is obtained. Furthermore, if the guide member (43) is formed of an elastic resin, the coaxial cable (22) can be held without being damaged.
