Claim 0:
1. An opening and closing device of a vehicle sliding door, comprising:
a first latch mechanism configured to maintain a sliding door in a closed state in cooperation with a first striker;
a second latch mechanism configured to maintain the sliding door in an opened state in cooperation with a second striker, the second latch mechanism differing from the first latch mechanism;
a power releaser configured to unlatch the first latch mechanism and the second latch mechanism by a first motor power;
a power closer configured to move a first latch of the first latch mechanism from a half-latched position to a fully latched position via a closing lever configured to transmit a second motor power to the first latch, the power closer being functionally different from the power releaser configured to unlatch the first latch mechanism and the second latch mechanism by the first motor power;
a cancel lever configured to cancel movement of the first latch toward the fully latched position by the second motor power, by blocking transmission of the second motor power from the closing lever to the first latch;
a lock mechanism configured to switch between an unlocked state and a locked state by a third motor power, the unlocked state being a state which allows unlatching of the first latch mechanism by operating the power releaser, the locked state being a state which does not allow unlatching of the first latch mechanism by operating the power releaser; and
a relay control mechanism that includes an inner handle, wherein
the lock mechanism, the power releaser, and the cancel lever are disposed in the first latch mechanism,
the relay control mechanism includes a handle lever configured to be coupled to the inner handle and to:
when a door opening operation is performed on the inner handle, rotate in a first direction to unlatch the first latch mechanism and activate the cancel lever, and
when a door closing operation is performed on the inner handle, rotate in a second direction to unlatch the second latch mechanism,
the inner handle is pivotally supported by a handle case of the relay control mechanism so as to be rotatable in two directions, and
the handle lever is pivotally supported by the handle case;

the relay control mechanism further includes a base panel that is fixed to an inner panel of the sliding door,
the handle case is fixed to the base panel,
a fully opened releasing lever and an inner relay lever are pivotally supported by the base panel,
the fully opened releasing lever is configured to rotate to unlatch the second latch mechanism when the handle lever is rotated in the second direction, and
the inner relay lever is configured to rotate to unlatch the first latch mechanism when the handle lever is rotated in the first direction.
