    • A racket frame 2 includes a body 4 and a first vibration-damping portion 6 fixed to the body 4. The body 4 includes a head 8, a shaft 12, a pair of throats 10 extending from the head 8 to the shaft 12, and a grip 14 connected to the shaft 12. The body 4 includes a second vibration-damping portion 18, and the material of the second vibration-damping portion 18 is different from the material of the first vibration-damping portion 6. The ratio (R2/R4) of a side pressure rigidity R2 to a throat rigidity R4 is 0.26 or greater, a moment of inertia around an axis at a position of 10 cm from a grip end is less than 300 kg·cm2, and a vibration damping rate in an out-of-plane secondary mode is equal to or greater than 0.70 but equal to or less than 1.0.

    • Mat-base assembly comprises a base including a sheet integrally formed of an elastomeric polymer, a picture frame-like projection formed on the periphery of the sheet and a mat-containing portion formed on the inner side of the peripheral projection, a dust-controlling mat contained in the mat-containing portion and a temporary anchoring mechanism for anchoring detachably the base and mat at a plurality of points on the peripheral edge of the sheet, wherein an anchoring element comprising engaging pieces implanted on a base fabric is fixed to the base, a fiber loop element engageable with the engaging pieces is sewn to the mat and the peripheral portion of the anchoring element is fusion-bonded to the base sheet while in the remaining portion of the anchoring element, the engaging pieces are left as they are.In this mat-base assembly, the durability of the anchoring mechanism is highly improved and good adaptability to the operation of attaching and detaching the dust-controlling mat is maintained for a long time. Furthermore, movement of the dust-controlling mat or roll-up of the corner portion of the mat can effectively be prevented.
    • 垫基组件包括基底,其包括由弹性体聚合物一体形成的片材,形成在片材周边上的相框形突起和形成在周边突起的内侧上的垫片部分, 包含在垫子部分中的垫子和用于在片材的周边边缘上的多个点处可拆卸地固定基部和垫子的临时锚固机构,其中包括植入基底织物上的接合片的锚固元件固定到基部 可与接合件接合的纤维环元件被缝合到垫子上,并且锚定元件的周边部分熔合到基片上,而在锚定元件的剩余部分中,接合件原样保持。 在这种垫基组件中,锚固机构的耐久性得到很大改善,并且长时间保持对安装和拆卸防尘垫的操作的良好适应性。 此外,可以有效地防止防尘垫的移动或垫的角部的卷起。
