本考案はモーターサイクルチユーブレスタイヤ
のビードスペーサのリムへの取付部の改良に関す

ペーサが用いられている。 In motorcycle tubeless tires, when the internal pressure of the tire decreases due to a puncture, etc., the bead part is used to prevent the bead part from invading the drop center part of the rim and causing the rim to come off, impairing driving safety. A so-called bead spacer is used that constantly presses the rim against the bead seat and flange of the rim.

挿通孔とのエアシール性が損われる等の問題点が
ある。 For example, as shown in FIG. 1, a conventional bead spacer 20 is a hard body that bridges both bead seat portions 2 of a rim 1 at a plurality of locations, and includes a bead spacer main body 2 having a tire bead pressing portion 21.
4 and a fixing member 23. As will be seen later, the above method has problems such as the air sealability between the bead spacer fixing member and the fixing member insertion hole of the rim being impaired due to vibrations during running.
本考案は上記問題点を解消すべく案出されたも

ている。 FIG. 2 shows the invention. That is, in the present invention, an annular groove 29 that opens only in the width direction is provided in the bead spacer fixing member 23, and an O-ring 30 is fitted therein, and this O-ring fits into the fixing member insertion hole 11 of the rim. The tire bead press part 21 of the bead spacer main body 24 should be
The bead spacer 2 is pressed so that the bead portion 16 of the rim 1 is pressed against the bead seat portion 2 and the flange portion 4 of the rim 1.
0 is attached to the rim 1, and the bead spacer fixing member 23 is inserted through the fixing member insertion hole 11 of the rim. In the figure, 13 indicates a nut for this attachment, 14 a screw for fixing this nut, and 12 a washer.

縮永久歪、ビードスペーサで押えられているタイ

ず、これに走行中の振動が加わることによりエア
シール性能が損われてしまう。 Now, in order to prevent the leakage of the air inside the tire, that is, to create an air seal, if a rubber grommet is used between the insertion of the bead spacer fixing member in the rim, the sealing performance can be temporarily exhibited. However, the compression set of the rubber grommet and the compression set of the inner wall rubber of the tire bead which is held down by the bead spacer cannot be avoided, and when vibrations during driving are added to this, the air seal performance is impaired.
これに対し本考案ではゴムグロメツトを用いず
Ｏリングを前記の如く用いているから、ビードス
ペーサはその固定部材に上下振動が加わつてもＯ
リングはリムの厚さの範囲でエアシールを充分行
う。 On the other hand, in the present invention, since the O-ring is used as described above without using the rubber grommet, the bead spacer does not operate even if vertical vibration is applied to the fixing member.
The ring provides a sufficient air seal within the thickness of the rim.
