A steering damper apparatus (30) for a two-wheeled vehicle includes a steering damper housing (31) with a lower end portion fixed to the motorcycle's main frame. A first torque arm (33) has a first end (43) fixed to a pivotally movable shaft, and a second end (44) which is connected, via a first pin (34), to a first end (45) of a second torque arm (35). The second torque arm (35) has a second end (46) bolted to a top bridge (37) on the main frame. The first and second torque arms are pivotally movable relative to one another, via the pivot shaft (32) and the first pin (34). The apparatus is capable of accommodating a change in distance between the pivot shaft and the bolt on the second torque arm. A two-part cover is provided for the steering damper body, including a housing cover secured to a fixed side thereof, and a torque arm cover secured to a movable side thereof.

To provide a braking force control apparatus for a saddle ride-type vehicle, which causes braking force to act when a rider drives a vehicle body forward and backward at low speed while supporting the vehicle. A braking force control apparatus for a saddle ride-type vehicle, including a control device (106) configured to control a clutch device (108) which connects and disconnects driving force between an engine (100) and a transmission (40), and brake devices (BF and BR) which generate braking force of at least one of a drive wheel (WR) and a front wheel (WF). The vehicle (1) is configured to be able to switch between a normal driving mode and a slow speed mode assuming driving at a speed reduction ratio on a lower speed side than the normal driving mode. An inclination angle θ in a pitching direction of the vehicle (1) is detected when the slow speed mode is selected. The brake devices (BF and BR) generate braking force (B) when the inclination angle θ is not less than a predetermined value. Then, upon input of a driving operation in the slow speed mode, switching of the clutch device (108) to a connected state is started, and the braking force (B) is gradually released once the driving force starts to be transmitted to the drive wheel (WR).

Problem To enable an operator to easily connect a universal joint to an output shaft of an engine. Means for Resolution A drive shaft 40 is connected to an output shaft 21 of an engine 20 which is mounted on a vehicle body 10 by way of a universal joint 30, and a wheel is connected to a distal end side of the drive shaft 40. Projection portions 33, 34 which project outwardly are formed on a yoke 31 of the universal joint 30 which is connected to the output shaft 21 by way of splines 22, 32. A swing arm 50 is rockably supported on the vehicle body 10 using one shaft 12, and the universal joint 30 is arranged above the shaft 12. A boot 70 is mounted between a distal end 51 of the swing arm 50 and a peripheral portion 20a of the output shaft.
