摘要： It is an object of the present invention to provide a useful inner structural supporter type run flat tire having enough structural strength for controlling the steering wheel to some extent when the tire goes flat and having easy structure for installing to the rim wheel. A wheel 10 has a flange 11 with a bead part of a tubeless tire fitted thereto and a container 12 having a diameter smaller than that of the flange 11, and comprises a rim valve for adjusting the air pressure of the tubeless tire, and a second rim valve for adjusting air pressure in an inner tire 20. The inner tire 20 is stored in the container 12. While the inner tire 20 is stored in the container 12, the tubeless tire 30 is fitted to the flange of the tire wheel 10, air is fed into the inner tire 20 via the second rim valve until the air pressure reaches a predetermined value, so the inner tire 20 is inflated inside the tubeless tire 30, and an inner tire is provided as the inner tire in the outer tubeless tire space.

摘要： A closed loop is formed by loop antenna elements which equivalently function as inductance, a capacitor inserted in such a manner as to divide the loop antenna into the loop antenna elements, and an impedance-matching dividing element for tuning the antenna and establishing matching with a high-frequency circuit side. A subsidiary substrate with the capacitor mounted thereon is fixedly installed by a retaining pawl of an antenna holder, and is connected to the loop antenna elements by being soldered thereto at a pair of lands on the subsidiary substrate. As a result, it is possible to improve the effective gain of the antenna and effectively utilize the substrate space.
