    • In a structure of mounting a wheel cap to a wheel, a plurality of pairs of support plates are projectingly provided on an inner wall of the wheel cap made of a synthetic resin and arranged annularly so that the support plates in each pair are opposed to each other in a circumferential direction. A pair of elastic support legs extending from opposed surfaces of the support plates in each pair are integrally connected to each other to form a V-shape. A locking claw is formed on a connection between the support legs and capable of being engaged into a locking recess in an inner peripheral surface of a rim of the wheel. An annular setting spring is connected to the locking claws for biasing the locking claws in a direction to come into engagement in the locking recess. Thus, it is possible to form each of the support legs supporting each of the locking claws sufficiently long to enhance the flexibility of the support leg, thereby improving durability of the support legs and mounting property of the wheel cap.
    • 在将轮盖安装到车轮的结构中,多个支撑板突出地设置在由合成树脂制成的车轮盖的内壁上,并且环形地布置,使得每对中的支撑板与每个支撑板相对 另一个在圆周方向。 在每对支撑板的相对表面上延伸的一对弹性支撑腿彼此一体地连接以形成V形。 锁定爪形成在支撑腿之间的连接部上并且能够接合到车轮边缘的内周表面中的锁定凹部中。 环形固定弹簧连接到锁定爪,用于沿着锁定凹槽中接合的方向偏压锁定爪。 因此,可以充分地形成支撑每个锁定爪的每个支撑腿以增强支撑腿的柔性,从而提高支撑腿的耐久性和车轮盖的安装性能。

    • Disclosed is a method for producing blow moldings of essentially polycarbonate resin. The blow moldings may have a relatively high percentage of hollowness, and may have a ribbed structure, and their wall thickness is uniform. Forming ribs in the blow moldings is easy. Also disclosed is a polycarbonate resin composition for the method. The polycarbonate resin composition is for gas assist injection molding and comprises (A) from 30 to 100% by weight of a polycarbonate resin and (B) from 0 to 70% by weight of a styrenic resin. The melt viscosity ratio, &eegr;H/&eegr;L, of the melt viscosity of the resin composition, &eegr;H (Pa·sec), measured at a shear rate of 10 (sec−1) at the optimum molding temperature to the melt viscosity thereof, &eegr;L (Pa·sec), at a shear rate of 1000 (sec−1), is at least 5. When the polycarbonate resin composition is molded into blow moldings in a mode of gas assist injection molding, the mold cavity volume is expanded while the pressure gas is still in the resin melt in the mold cavity. Provided are the blow moldings of the polycarbonate resins produced in the gas assist injection molding method.

    • An inner and outer pressure difference alleviating device for an air tight case (10) is provided including a housing (20) and a cover (30). The cover is adapted to close an opening in housing (20). A diaphragm portion (34) that is made from a flexible material is formed integrally with cover (30) or a side wall of the housing (20). When a pressure difference between the inside and outside of the airtight case (10) is produced by heat generated by electric and electronic components contained in housing (10) diaphragm portion (34) elastically deforms to change the inner volume of airtight case (10) and eliminate the pressure difference between the inside and outside of airtight case (10) automatically, while retaining the air-tightness of the airtight case (10).
