Abstract: A shifting mechanism in which an inclination of a sleeve with respect to a shift fork is reduced while maintaining a clearance between the shift fork and the sleeve. In the shifting mechanism, an engagement groove is formed entirely around a shift sleeve, and a cutout is formed on the engagement groove. A first diameter of the shift sleeve between predetermined sites of the bottom of the engagement groove within the cutouts is shorter than a second diameter of the shift sleeve between predetermined sites of the bottom of the engagement groove. A straight-line distance between the engagement ridges formed on both ends of the shift fork is longer than the first diameter but shorter than the second diameter.

Abstract: A power transmission apparatus for a vehicle includes an engagement mechanism and a switching mechanism. The switching mechanism includes: a hydraulic cylinder; a regulation valve regulates a hydraulic pressure to be supplied to a first oil chamber and a second oil chamber; a rocking valve switches a state of a hydraulic circuit between a closed circuit state and an open circuit state; and an oil pump supplies the hydraulic pressure to the hydraulic cylinder. The switching mechanism switches the engagement mechanism between an engaged state and a disengaged state after the hydraulic circuit is switched from the closed circuit state to the open circuit state by the rocking valve. The switching mechanism keeps the engaged state or the disengaged state of the engagement mechanism after switching the engaged state or the disengaged state of the engagement mechanism.

Abstract: A selectable one-way clutch includes an engagement mechanism. The engagement mechanism is configured to be switched between an engaged state and a disengaged state. The engaged state is a state in which relative rotation between a first and a second members in one of a positive rotational direction and a reverse rotational direction is restricted. The disengaged state is a state in which the relative rotation between the first member and the second member in both of the positive and the reverse rotational direction is permitted. The electronic control unit is configured to apply torque to the one of the first member or the second member by using a motor such that relative rotation in the other one of the positive or the reverse rotational direction is generated between the first member and the second member when the engagement mechanism is switched from the engaged state to the disengaged state.

Abstract: A selectable one-way clutch includes: a fixed plate; an annular rotating plate that faces the fixed plate and rotates relative to the fixed plate; an engagement piece that is held by the fixed plate to protrude toward the rotating plate; an engagement concave portion formed on the rotating plate to be engaged with the engagement piece; and an annular selector plate placed between the fixed plate and the rotating plate and switches states of the engagement piece, the selectable one-way clutch selectively switching between an engagement state in which the engagement piece engages with the engagement concave portion and a release state in which rotations of the rotating plate in both directions are allowed. Further, notch portions are formed on an outer periphery portion of at least one of the selector plate and the rotating plate to have a shape passing through the plate in a thickness direction.
