A steering roll connector for a vehicle comprising: a roll stator fixed to the vehicle; a roll rotor arranged coaxially and rotatably with respect to the roll stator, the roll rotor including a rotor connector provided with a steering wheel connector; a roller plate rotatably disposed between the roll stator and the roll rotor; and a locking unit configured to maintain the steering roll connector in a neutral position when a steering wheel shaft of the vehicle is not mounted on the steering roll connector, and enable the roll rotor to be rotated relative to the roll stator when the steering wheel shaft of the vehicle is mounted on the steering roll connector, wherein the locking unit comprises: a locking part disposed at a rotor locking mounting part disposed at a roll rotor side; and a locking mounting part disposed at a roll stator side to cause a change in an engagement state by the driving of the locking part, wherein the locking part comprises: a locking block movably disposed at the rotor locking mounting part; a locking elastic part configured to abut at one end thereof against the rotor locking mounting part and abut at the other end thereof against the locking block to elastically support the locking block; and a locking hinge part brought into close contact at one end thereof with the locking block and brought into close contact at the other end thereof with a steering wheel shaft side of the vehicle in such a manner as to be disposed at the other end thereof pivotally at the roll rotor, wherein the locking block comprises: a locking block body movably disposed at the rotor locking mounting part; an elastic part-mounting part disposed at one end of the locking block body to support the locking elastic part; a hinge contact part formed at the locking block body to come into close contact with the locking hinge part; and a movable part formed at the other end of the locking block body so as to be engaged with the locking mounting part. a roll stator fixed to the vehicle; a roll rotor arranged coaxially and rotatably with respect to the roll stator, the roll rotor including a rotor connector provided with a steering wheel connector; a roller plate rotatably disposed between the roll stator and the roll rotor; and a locking unit configured to maintain the steering roll connector in a neutral position when a steering wheel shaft of the vehicle is not mounted on the steering roll connector, and enable the roll rotor to be rotated relative to the roll stator when the steering wheel shaft of the vehicle is mounted on the steering roll connector, wherein the locking unit comprises: a locking part disposed at a rotor locking mounting part disposed at a roll rotor side; and a locking mounting part disposed at a roll stator side to cause a change in an engagement state by the driving of the locking part, wherein the locking part comprises: a locking block movably disposed at the rotor locking mounting part; a locking elastic part configured to abut at one end thereof against the rotor locking mounting part and abut at the other end thereof against the locking block to elastically support the locking block; and a locking hinge part brought into close contact at one end thereof with the locking block and brought into close contact at the other end thereof with a steering wheel shaft side of the vehicle in such a manner as to be disposed at the other end thereof pivotally at the roll rotor, wherein the locking block comprises: a locking block body movably disposed at the rotor locking mounting part; an elastic part-mounting part disposed at one end of the locking block body to support the locking elastic part; a hinge contact part formed at the locking block body to come into close contact with the locking hinge part; and a movable part formed at the other end of the locking block body so as to be engaged with the locking mounting part. a locking part disposed at a rotor locking mounting part disposed at a roll rotor side; and a locking mounting part disposed at a roll stator side to cause a change in an engagement state by the driving of the locking part, wherein the locking part comprises: a locking block movably disposed at the rotor locking mounting part; a locking elastic part configured to abut at one end thereof against the rotor locking mounting part and abut at the other end thereof against the locking block to elastically support the locking block; and a locking hinge part brought into close contact at one end thereof with the locking block and brought into close contact at the other end thereof with a steering wheel shaft side of the vehicle in such a manner as to be disposed at the other end thereof pivotally at the roll rotor, wherein the locking block comprises: a locking block body movably disposed at the rotor locking mounting part; an elastic part-mounting part disposed at one end of the locking block body to support the locking elastic part; a hinge contact part formed at the locking block body to come into close contact with the locking hinge part; and a movable part formed at the other end of the locking block body so as to be engaged with the locking mounting part. a locking block body movably disposed at the rotor locking mounting part; an elastic part-mounting part disposed at one end of the locking block body to support the locking elastic part; a hinge contact part formed at the locking block body to come into close contact with the locking hinge part; and a movable part formed at the other end of the locking block body so as to be engaged with the locking mounting part.
