  • a through portion 85, a canopy portion 84 for preventing corotation of the protector 83 when the vehicle speed sensor 77 is tightened together, and a substantially rectangular opening 86 are provided.
  • the eaves portion 84 and the opening 86 of the protector 83 have a function of preventing the protector 83 from rotating together with the fastening member 81 when the vehicle speed sensor unit 76 is attached. Specifically, when protector 83 tries to rotate clockwise with tightening of fastening member 81, the end face of opening 86 abuts on the cylindrical side surface of vehicle speed sensor 77, and the eaves portion bent toward the lower side of the vehicle body The inner side surface of 84 abuts on the cylindrical side surface of the vehicle speed sensor 77. Thus, the rotational operation of the protector 83 is restricted. Further, since the output wiring passing portion 85 is formed in the protector 83, the protector 83 can be attached in a state where the output wiring 77a is connected to the ceiling surface of the vehicle speed sensor 77.
  • a relief 88 is formed at the edge of the flat plate 87.
  • the relief portion 88 suppresses the protrusion of the protector 83 to the outer side in the vehicle width direction. The specific effects will be described later.
  • the crankcase 64 is provided with a plurality of fastening bolts 75 for connecting the left case half 64L and the right case half 64R so as to be directed in the vehicle width direction.
  • the fastening bolt 75 disposed on the front side of the vehicle adjacent to the middle hanger boss 64b is disposed at a position overlapping the vehicle speed sensor unit 76 in a side view of the vehicle.
  • the middle hanger boss 64 b is disposed close to the vehicle speed sensor unit 76 so as not to overlap in a side view of the vehicle body.
  • FIG. 8 is a plan view showing the engagement relationship between the hanger plates 100L, 100R and the engine 23.
  • FIG. 9 is an enlarged layout view of the vehicle speed sensor unit 76 as viewed from above in the axial direction.
  • the vehicle speed sensor unit 76 is disposed so that the periphery of the fastening member 81 is exposed from the left hanger plate 100L, and the ribs 65, 66, 69 disposed around the bulging portion 89.
  • the end face of the relief portion 88 of the protector 83 is located inward of the end face of the rib 66 in the vehicle width direction by a distance T in FIG. Is shown.
  • the relief portion 88 formed in the protector 83 is configured to be directed in the front-rear direction of the vehicle body when the vehicle speed sensor unit 76 is fixed at a predetermined position. Thereby, the protrusion of the protector 83 to the outside in the vehicle width direction is suppressed, and the drive sprocket 127 attached to the end of the countershaft 35 and the drive chain 39 wound around this interfere with the protector 83 and the vehicle speed sensor 77. You can prevent.
  • the axis O of the cylindrical main body 78 of the vehicle speed sensor 77 is inclined toward the rear of the vehicle by a predetermined angle ⁇ in a side view of the vehicle.
  • a protector 83 covering the upper portion of the vehicle speed sensor 77 and a fastening member 81 are cofastened at a position on the vehicle body upper side of the countershaft 35 and a vehicle rear side of the shift drum 150, thereby fixing to the crankcase 64.
  • the vehicle speed sensor 77 is disposed on the vehicle body upper side of the auxiliary shaft 35, and the maintainability of the vehicle speed sensor 77 can be improved as compared with the structure attached to the rear surface of the crankcase 64.
  • the protector 83 protects the vehicle speed sensor 77. Furthermore, by fastening the vehicle speed sensor 77 and the protector 83 together, the number of fastening members 81 can be reduced, and the cost can be reduced.
  • the forms of the vehicle and engine, the structure and shaft arrangement of the transmission, and the shapes and structures of the crankcase, ribs around the bulging portion, vehicle speed sensor, protector, shift drum, etc. are not limited to the above embodiment, and various modifications Is possible.
