Patent ID: 8276997

Claim:
In a motorcycle including: a body frame; an engine mounted on said body frame, said engine comprising an engine body and a cylinder head which is on an upper side of said engine body; a fuel tank disposed above an intake system which is connected to and which extends upwardly from said cylinder head; a wheel brake; and a manually operable brake operating element which is fluidly connected to said wheel brake; the improvement comprising a brake-by wire system comprising: an operation amount detector for detecting an amount of force applied to the brake operating element; a pressure-generating unit for generating a hydraulic pressure separately from an operation of said brake operating element, a pressure-regulating unit interposed between said hydraulic pressure generating mechanism and the wheel brake, and operable to regulate an output hydraulic pressure of said automated hydraulic pressure generating mechanism and to apply the regulated hydraulic pressure to said wheel brake, the pressure-regulating unit comprising a substantially box-shaped block having a plurality of components embedded therein, and a plastic cover member attached to the block and covering outwardly-projecting parts of the components embedded in said block, wherein the cover member comprises an integral terminal connector for matingly engaging a corresponding connector therein, and a control unit for controlling operation of said pressure-regulating unit on the basis of input from said operating amount detector, said control unit also operable to control operation of said pressure-generating unit; wherein said pressure-regulating unit is disposed between said engine body and said fuel tank; and wherein said pressure-regulating unit is flexibly supported, through a flexibly resilient member, by a support member which is operatively attached to said body frame, said flexibly resilient member comprising a two-part case including an upper case member and a lower case member which cooperates with the upper case member to substantially surround the block, and wherein said lower case member comprises a plurality of integrally formed spaced apart, substantially L-shaped corner projections for supporting said pressure regulating unit thereon.
