A straddled vehicle including: a vehicle body frame having a head pipe and a down frame extending downward and rearward from the head pipe; a steering shaft rotatably inserted in the head pipe; a front fork linked to the steering shaft, the front fork including an outer tube and an inner tube that is slidably inserted in the outer tube; a bottom bridge linking the front fork and a portion of the steering shaft that is downward relative to the head pipe; a radiator arranged rearward of the front fork, the radiator overlapping the outer tube in a front view; a front wheel supported by the front fork; a front fender arranged upward of the front wheel; and a rectifier member attached to a portion of the outer tube that is upward of the front wheel and downward of the bottom bridge, the rectifier member extending rearward.

A saddle-ride vehicle includes: left and right seat rails; left and right sub-frames; and a rear fender assembled from a lower side. The rear fender has a base portion and left and right vertical wall portions. The base portion forms a housing space for vehicle body components. Separation distance of the left and right vertical wall portions is smaller than separation distance of the left and right sub-frames. At upper parts of the left and right vertical wall portions each are provided with an eaves portion extending outward in a vehicle width direction to fill a gap between the vertical wall portion and the frames. The eaves portions overlap with the seat rails in an up-down direction, and the eaves portions each have a guide portion.

A pasting device for reducing wind resistance of a bicycle is disclosed. The pasting device includes a pasting body; a side of the pasting body is a pasting side, and other side of the pasting body is a windward side, and the pasting body includes a pasting layer disposed on the pasting side, and a plurality of granular parts protruded on the windward side. The plurality of granular parts can form a diversion effect to reduce wind resistance when the bicycle is traveling windward.

In an internal combustion engine, a gasket is disposed between joining surfaces of a cylinder block and a cylinder head, and a heat radiation rib that extends in a cylinder axis direction is formed on the cylinder block or the cylinder head. In such an internal combustion engine, the gasket includes: a portion to be sandwiched that is sandwiched between the joining surfaces; and an extending portion that protrudes toward an outside from the portion to be sandwiched as viewed in a cylinder axis direction.

A three wheeled vehicle is provided that can include a frame, a steerable front wheel secured to a front end of the frame, a first trailing wheel arm having a first rear wheel secured thereto and a second trailing wheel arm having a second rear wheel secured thereto, and a central suspension joint secured to the frame on which the first and second trailing wheel arm is rotatably secured on either side of the frame. Further, the vehicle can include a horizontal linkage pivotably connected on the frame at the midsection beneath the first and second trailing wheel arms and linked to an underside of the first and second trailing wheel arm between the first wheel and the central suspension joint proximal to a first end of the horizontal linkage and between the second wheel and the central suspension joint proximal to a second end of the horizontal linkage, respectively.

It is described a process for producing transparent ceramic bodies with at least two zones having different garnet composition, in particular in which one of said zones has composition Y.sub.3AI.sub.5O.sub.12. The invention is especially useful for the production of transparent ceramic bodies having preset complex shapes and/or a controlled complex distribution of doping ions.
