Disconnector apparatus

A disconnector apparatus comprising:

• a casing having therein a support ring and one side gear, the one side gear being configured to engage with a pinion gear disposed in the support ring;
• and
• a clutch ring connected to an actuator device by a sleeve and movable by an operation of the actuator device, the clutch ring comprising a first clutch disposed on an inner-diameter portion of the clutch ring at one side of the clutch ring facing the one side gear, and a second clutch disposed on one inner surface of the inner-diameter portion,
• wherein the first clutch is configured to engage with a third clutch disposed on an outer-diameter portion of the support ring at one side of the support ring by a first moving operation of the clutch ring by a first operation of the actuator device, and
• wherein the second clutch is configured to engage with a fourth clutch disposed on one surface of the one side gear by a second moving operation of the clutch ring by a second operation of the actuator device,
• wherein the clutch ring has a plurality of leg parts, the plurality of leg parts extending toward the sleeve from another side of the clutch ring, and an end of each of the plurality of leg parts is disposed outside of the casing through a corresponding through-hole of the casing and connected to the sleeve, and
• wherein a contact surface of each of the plurality of leg parts in contact with the corresponding through-hole has an inversely tapered structure, wherein a width of the contact surface decreases in a direction from the end of each of the plurality of leg parts toward the corresponding through-hole.
