Transfer for vehicle

A transfer for a vehicle, the transfer comprising:

• an input shaft;
• an output shaft arranged on a common axis that is in common with the input shaft;
• a high/low switching mechanism that changes a speed of rotation of the input shaft and transmits the rotation to the output shaft;
• an output member that outputs motive power to a destination that is different from that of the output shaft;
• a clutch that transmits a part of motive power from the output shaft to the output member or shuts off the transmission, or adjusts a transmitted torque to be transmitted to the output member;
• a motor;
• a ball cam including a first annular member, and a second annular member positioned on the clutch side, the first annular member and the second annular member being each supported on the output shaft so as to be rotatable relative to the output shaft, including respective inclined recess grooves formed in surfaces facing each other and being prevented from moving in the common axis direction, and a spherical rolling element housed in the inclined recess grooves of the first annular member and the second annular member, either of the first annular member and the second annular member being driven to rotate around the common axis by the motor to move the second annular member to the clutch side;
• a transmission mechanism that transmits movement in the common axis direction of the second annular member to the clutch;
• a fork shaft disposed in parallel to the common axis and supported so as to be movable in an axis direction;
• a cam engagement member connected to the fork shaft;
• a drum cam including a cam groove formed in an outer peripheral portion, the cam groove engaging with the cam engagement member, being connected to either of the first annular member and the second annular member and pivoting around the common axis to move the cam engagement member to the axis direction of the fork shaft;
• and
• a fork connected to the fork shaft, the fork transmitting movement in the axis direction of the fork shaft to the high/low switching mechanism that switches between a high gear and a low gear.
