Abstract | PROBLEM TO BE SOLVED: To provide a holding member for a support core for a tire that can render processing for a ventilation hole to the core unnecessary, enhance degrees of freedom of a position of a valve to be arranged in a rim and further can improve performance of constraint of the core to the rim.SOLUTION: A holding member 5 made of rubber, which is arranged between an outer peripheral surface of a rim 1 to which a pneumatic tire 3 is fitted and a core 4 in a toric shape that supports the pneumatic tire 3 from inside when inner pressure of the pneumatic tire 3 decreases, is constituted of an annular body 50 having a recessed part 51 for receiving a base end part of the core 4 provided on an outer peripheral surface 50B thereof and has: an inner ventilation hole 52 which opens to an inner peripheral surface 50A of the annular body 50; an outer ventilation hole 53 which opens to the outer peripheral surface 50B of the annular body 50 at a position away from the recessed part 51 of the annular body 50; and a penetration hole 54 that penetrates through inside of the annular body 50 and connects the inner ventilation hole 52 and the outer ventilation hole 53 to each other.SELECTED DRAWING: Figure 1
【課題】 中子に対する通気穴の加工を不要にすると共に、リムに配設されるバルブの位置の自由度を高めることを可能にし、更にはリムに対する中子の拘束性を改善することを可能にしたタイヤ用支持中子の保持部材を提供する。【解決手段】 空気入りタイヤ3が嵌合されるリム1の外周面と空気入りタイヤ3の内圧低下時に該空気入りタイヤ3を内側から支持する円環状の中子4との間に配設されるゴム製の保持部材5であって、中子4の基端部を受容する凹部51を外周面50Bに備えた環状体50からなり、該環状体50の内周面50Aに開口する内側通気穴52と、環状体50の凹部51から外れた位置において環状体50の外周面50Bに開口する外側通気穴53と、環状体50の内部を貫通して内側通気穴52と外側通気穴53とを互いに連結する貫通孔54とを有する。【選択図】 図1 |
