Abstract
A stand device for a motorcycle includes an interlocking mechanism having a coil-formed stand spring connected to a stand at one end thereof. A spring support member has a spring support portion connected with the other end of the stand spring and is interlocked and connected to an operating element so that the position of the spring support portion can be changed according to a manual operation of an operating element. The position of the spring support portion determined according to the operation of the operating element toward the erect position side is so set that the stand spring is put in the state of urging the stand toward the erect position side.

  • 3. The stand device for a motorcycle as set forth in claim 2, wherein said interlocking mechanism includes: an erecting operating force transmitting mechanism by which a manual operating force for operating said operating element toward a side for turning said stand from said stored position to said erect position side is transmitted to said spring support member side; anda storing operating force transmitting mechanism by which a manual operating force for operating said operating element toward a side for turning said stand from said erect position to said stored position side is transmitted to said spring support member side, and the position of said spring support portion determined according to an operation of said operating element to the stored position side is so set as to put said stand spring into the state of urging said stand toward said stored position side.
  • 4. The stand device for a motorcycle as set forth in claim 2, wherein said interlocking mechanism includes: a turning lever turned about an axis parallel to the axis of turning of said spring operating member according to a manual operation of said operating element; anda transmission mechanism that transmits a turning force of said turning lever to said spring support member, said transmission mechanism being provided between the other end portion of said spring support member and said turning lever.
  • 5. The stand device for a motorcycle as set forth in claim 3, wherein said interlocking mechanism includes: a turning lever turned about an axis parallel to the axis of turning of said spring operating member according to a manual operation of said operating element; anda transmission mechanism that transmits a turning force of said turning lever to said spring support member, said transmission mechanism being provided between the other end portion of said spring support member and said turning lever.
  • 6. The stand device for a motorcycle as set forth in claim 1, wherein a shock absorber is provided between said stand and a vehicle body frame.
  • 7. The stand device for a motorcycle as set forth in claim 1, wherein an auxiliary urging mechanism designed for changeover between a state of urging said stand toward said erect position side and a state of urging said stand toward said stored position side is provided between said stand and said support body, separately from said stand spring.
  • 8. The stand device for a motorcycle as set forth in claim 1, wherein the center of a turning shaft of said spring support member is disposed in a region surrounded by a locus along which the point of connection of said one end of said stand spring to said stand is moved according to turning of said stand, a straight line connecting the point of connection of said one end of said stand spring to said stand with said spring support portion at the time when said stand is in its stored position, and a straight line connecting the point of connection of said one end of said stand spring to said stand with said spring support portion at the time when said stand is in its erect position.
  • 9. A stand device for a motorcycle, comprising: a stand shaft attached to a stand, said stand shaft being borne on a vehicle body frame or a support body fixed to said vehicle body frame, in such a manner that said stand can be turned between an erect position for obtaining a parking condition and a stored position for canceling the parking condition;a one-way clutch having an outer ring, said one-way clutch being mounted to said stand shaft; anda clutch operation control mechanism that is capable of inhibiting rotation of said outer ring in the condition where said stand is in the erect position,wherein said one-way clutch is mounted to said stand shaft in such a manner that in the condition where said stand is in said erect position, rotation of said outer ring is inhibited by said clutch operation control mechanism, and turning of said stand toward said stored position side is inhibited.
