A frame structure of a saddle type vehicle that can easily secure the bending strength of welded portions by a structure that seat rails are welded to rear portions of pivot frames, etc. is provided. Elongated holesA extending along an axis L of a front portionF of the seat rail is provided to a side surface of the pivot frame, and the pivot frameand the front portionF of the seat rail are welded to each other at the peripheral edge of the elongated holeA.

A transmission casing for a bicycle has sufficient strength and rigidity and has a simple structure while being capable of hermetically sealing a transmission body of the bicycle. In a transmission casing for a bicycle is covered with a casing and a plurality of transmission shafts supported by the casing. The transmission casing includes a light-metal-made reinforcing member made of aluminum, a light alloy or the like which supports shaft portions of the plurality of transmission shafts, and a fiber-reinforced-plastic-made cover member which is integrally laminated to an inner surface of the light-metal-made reinforcing member so as to hermetically seal the transmission body. The light-metal-made reinforcing member has a strength necessary for supporting the plurality of transmission shafts, and the fiber-reinforced-plastic-made cover member has a residual rigidity by subtracting rigidity obtained by the metal-made-reinforcing member from the rigidity necessary for preventing the deformation of the whole casing.

A motor vehicle vibrating system vibrates a motor vehicle having front and rear axles rotatably supported on a motor vehicle frame to simulate the load which would be applied from an actual road to the motor vehicle. The motor vehicle vibrating system has a first vibrator for vertically vibrating the rear axle, a second vibrator for vertically vibrating the front axle, and a third vibrator for vibrating one of the front and rear axles back and forth in a longitudinal direction of the motor vehicle.
