Transfer for four-wheel drive vehicle

A transfer for a four-wheel drive vehicle, comprising:

• a case;
• an input shaft that is supported by the case so as to rotate with respect to the case;
• a output shaft that is supported, concentric with the input shaft, by the case so as to rotate with respect to the case, the output shaft configured to output power to first left and right driving wheels;
• a output member that is supported concentric with the output shaft so as to rotate relatively with respect to the output shaft, the output member configured to output power to second left and right driving wheels;
• a friction clutch configured to transmit some of the power of the output shaft to the output member;
• an actuator;
• a pressing mechanism configured to apply engaging force to the friction clutch by output of the actuator;
• a locking sleeve that is arranged relatively non-rotatable with respect to the output shaft, the locking sleeve configured to move in a first axial direction along an axis of the output shaft with respect to the output shaft, the locking sleeve configured to selectively connect to the output member by moving in the first axial direction, an outer peripheral surface of the locking sleeve including a cam groove such that a groove width of the cam groove in a rotational direction of the locking sleeve decreases from the output shaft toward the output member;
• a first locking sleeve driving mechanism configured to drive the locking sleeve toward the output member side by the output of the actuator;
• and
• a second locking sleeve driving mechanism configured to move the locking sleeve independently of the actuator and the first locking sleeve driving mechanism, the second locking sleeve driving mechanism including a pushpin, the pushpin configured to move in a second axial direction that is perpendicular to the first axial direction and engage with the cam groove, the pushpin configured to move the locking sleeve toward the output member side as the locking sleeve rotates when the pushpin is engaged with the cam groove.
