Clutch-by-wire system

1. A clutch-by-wire system comprising:

a clutch lever body which is operated by an occupant;

a main body support portion which engages with the clutch lever body and rotates around a rotation axis;

a reactive force generation device which engages with the main body support portion and generates an operation reactive force on the clutch lever body; and

a rotation sensor which detects a rotation angle of the main body support portion,

wherein the main body support portion is formed to have a U-shaped cross section which opens in a direction orthogonal to the rotation axis and in which the clutch lever body is inserted inside, engages with the clutch lever body at a first location in an opening direction with respect to the rotation axis, and engages with the reactive force generation device at a second location in a direction opposite to the opening direction with respect to the rotation axis.

2. The clutch-by-wire system according to claim 1 , further comprising a shaft member which rotates around the rotation axis together with the clutch lever body and the main body support portion,

wherein the rotation sensor detects a rotation angle of the shaft member.

3. The clutch-by-wire system according to claim 1 , wherein the clutch lever main body is in close contact with the main body support portion directly or via another member at a plurality of locations in an axial direction of the rotation axis.

4. The clutch-by-wire system according to claim 1 , wherein the clutch lever body is sandwiched by the main body support portion from both sides in the axial direction of the rotation axis.

5. The clutch-by-wire system according to claim 1 , wherein the main body support portion includes a roller which is in contact with the reactive force generation device.

6. The clutch-by-wire system according to claim 1 , wherein the rotation sensor is disposed below the clutch lever body.
