In a brake system for a motorcycle in which the operation of a pressure-regulating unit interposed between fluid pressure generator and a wheel brake is controlled by a control unit on the basis of a value detected by operating amount detector for detecting an operating amount of a brake operating element, to prevent the influence of vibrations transmitted from an engine from being exerted on the pressure-regulating unit. A support member for supporting the pressure-regulating unit is flexibly supported, though elastic members, by a pair of frame sections which are arranged on both the left and right sides of an engine body and by a crossmember which connects both the frame sections to each other on the rear side of the engine body so as to constitute a part of a body frame F together with the frame sections.

A motorcycle includes a liquid pressure-generating unit, a pressure-regulating unit interposed between the liquid pressure-generating unit and a wheel brake, and a control unit for controlling operation of the pressure-regulating unit. The motorcycle also includes a support case, supportively containing the control unit and disposed on a lateral side of an engine body mounted on a body frame of the motorcycle, with the support case interposed between the control unit and the engine body. Further, a running airflow leading-in part for permitting traveling airflow to pass toward said control unit is formed at a front part of the support case, and a traveling airflow leading-out part is formed at a rear part of the support case for leading out the traveling airflow after the airflow has passed through at least one lateral side of the control unit. This arrangement lessens the influence of the heat from an engine upon the control unit while disposing the control unit in the vicinity of the engine body.

A brake system for a motorcycle includes a pressure-regulating unit interposed between a fluid pressure-generating unit and a wheel brake. Operation of a pressure-regulating unit is managed and controlled by a control unit, based primarily on an applied force detected by an operating amount detector. The fluid pressure-generating unit is disposed between an engine body, mounted on a body frame, and an exhaust pipe which is connected to a front surface of a cylinder head of the engine body, and which extends downwardly from the cylinder head. The fluid pressure-generating unit is arranged on the body frame such that, during operation of the motorcycle, the fluid pressure-generating unit is substantially shielded and isolated from heat emitted by the engine body and the exhaust pipe.

In a brake-by-wire brake system for a motorcycle, a pressure regulator is interposed between a pressure-generating unit and a brake caliper to regulate an output hydraulic pressure of the pressure generator, and to apply the regulated hydraulic pressure to a brake caliper. The pressure regulator is controlled by a control unit, based on input from an applied operating force detector, to minimize or prevent influences of engine vibration and heat on the pressure regulator. The pressure regulator is arranged between an engine body and a fuel tank disposed in back of an intake system connected to and extending upwardly from a cylinder head of the engine body; where the intake system is disposed on an upper side of the engine body. The pressure regulator is flexibly supported, through a flexibly resilient case, by a support cage attached to a body frame.

The present invention relates to a polyimide metal laminate which is a metal laminate comprising a stainless steel layer/a conductor layer/a polyimide resin layer/a metal layer, wherein the conductor layer is interposed between the stainless steel layer and the polyimide resin layer as a ground, and having a strong adhesion between the conductor layer and the polyimide resin layer, thus being able to be processed and used as a hard disk suspension. Specifically, the metal laminate of the present invention is characterized in that a surface of the conductor layer in contact with the polyimide resin layer is not smooth (preferably its 10-point average surface roughness is 0.5 μm or more).
