Abstract: A rear vehicle body structure including a rear side member, a side sill inner, and a rear floor. The rear side member includes a front portion connected to the side sill inner, a middle portion, and a rear portion disposed on a transversely inner side of the front portion. The rear portion has a first wall on its transversely outer side, and the middle portion has a second wall continuously provided from the first wall to the front portion. The side sill inner has a third wall accommodated within width of the rear side member and connected to the rear side member and the rear floor. The third wall has, on its rear end, a flange portion fixed to the rear side member at a vicinity of a transition point from the first wall to the second wall, on substantially the same plane as the third wall.

Abstract: A polishing machine of the present invention is capable of uniformly polishing a member to be polished with high flatness, and polishing cloth, which is employed in the polishing machine, is uniformly abraded. In the polishing machine, a polishing plate is capable of rotating. A supporting table rotatably supports the polishing plate. A rotary driving mechanism is mounted on the supporting table, and it rotates the polishing plate. A base supports the supporting table. An orbital driving mechanism moves the supporting table along a circular orbit without spinning about its own axis.

Abstract: A vehicle body structure comprises a cowl member, serving as a transversely extending vehicle structural member, having lateral end portions thereof secured to right and left strut towers at top ends of the strut towers to bridge the strut towers.

Abstract: A multifrequency piezoelectric sound-generating system is provided with a piezoelectric vibrator for generating audible sound at two or more resonance frequencies, an oscillator circuit connected to the piezoelectric vibrator for oscillating at one of the resonance frequencies, and a modulator circuit connected to the oscillator circuit for amplitude-modulating the oscillator circuit with a modulating frequency substantially equal or close to a frequency separation between the resonance frequencies to energize the piezoelectric vibrator with frequency-modulated waves to generate multifrequency audible sound.The modulator circuit may have a frequency divider that is operative in response to an oscillating frequency in the oscillator circuit for dividing or counting down the oscillating frequency into the modulating frequency to modulate the oscillator circuit therewith.

Abstract: An improved sealing structure for receiving a gas-filler hose in a vehicle is described. The sealing structure comprises a neck member having pair of stepped flange portions. Annular sealing members are applied on respective flange portions and clamped between the respective flange portions and a gas-filler base and an outer panel of a rear wheel housing.
