Abstract: There is provided an electrical accessory mounting device capable of adjusting an electrical accessory to the position viewable from a rider. The mounting device of the navigation apparatus 20 mounted on the steering stem pipe 3 of the saddle-type vehicle 1 comprises the fixture 4 mounted on the saddle-type vehicle 1, the bracket 5 holding the navigation apparatus 20, and the angular setting means 37 making at least part of the bracket 5 movable to the fixture 4 in the longitudinal direction of the saddle-type vehicle 1 and setting an angle of the bracket 5 to a predetermined angle by the position corresponding to the movement of the bracket 5. The angular setting means 37 includes a pair of long holes 34, 35 provided on the fixture 4 and a pair of screws 36F, 36B moving along a pair of long holes 34, 35 provided on the bracket 5.

Abstract: A method and apparatus for manufacturing an exhaust pipe assembly which are capable of decreasing a temperature difference between a seam-welded outer and inner surface at the time of seam welding. The apparatus comprises an outer circumferential electrode wheel abutted on an outer circumference of a mounting ring, a pressing means pressing the outer circumferential electrode wheel to the mounting ring, an inner circumferential electrode wheel abutted on an inner circumference of a pipe making up an exhaust pipe assembly, a transformer serving as a voltage supply means for supplying a predetermined voltage to the outer and inner circumferential electrode wheels and, and a controller for controlling voltage of the transformer. Thickness T1 of the outer circumferential electrode wheel is larger than thickness T2 of the inner circumferential electrode wheel.

Abstract: There is provided an accessory mounting device for a saddle riding type vehicle. An accessory mounting device for mounting a navigation device on a fuel tank comprises a base body on which the navigation device is mounted, and permanent magnets caused to stick to the fuel tank and thus allowing the base body to be mounted thereon. The permanent magnets are provided on the base body via spherical joints. In this sense, the permanent magnets are caused to stick to the fuel tank in a manner such that directions thereof are changed depending on a shape of the fuel tank, thus obtaining a stable mounting structure. Further, since there is no need to provide flexible members around the permanent magnets, an excellent durability is achieved. Furthermore, the base body comprises a bracket for holding the car navigation device, and an angle of the bracket can be adjusted.

Abstract: A silencer capable of preventing a damage of a metallic layer formed on an inner surface of an external cylinder formed from CFRP, and the external cylinder for the silencer. The silencer 1 includes the external cylinder 2, an internal cylinder 3 and an acoustic absorbent (not shown). A posterior end 2r of the external cylinder 2 is detachably provided with a tail cap 4. An anterior end 2f of the external cylinder 2 is detachably provided with a coupling body 5. An inner circumferential surface of the posterior end 2r of the external cylinder 2 includes a posterior covering portion 30 while an inner circumferential surface of the anterior end 2f thereof includes an anterior covering portion 32. This posterior covering portion 30 covers a posterior end portion 8r of a metallic layer 8 while the anterior covering portion 32 covers an anterior end portion 8f thereof.
