Connector of wiper blade device

Provided is a connector (110) of a wiper blade device which connects a wiper blade (400) selectively to a first wiper arm (200) and a second wiper arm (200') of different sizes. The connector (110) includes: a body (111) which includes a pair of sidewalls facing each other and an upper surface formed adjacent to the sidewalls; a pin insertion portion (120) which is formed in the sidewalls in a widthwise direction of the body (111) and into which a first pin (210) of the first wiper arm (200) or a second pin (210') of the second wiper arm (200') can be inserted; and a plurality of slits (130) which are formed in the upper surface of the body (111) along a lengthwise direction of the body, wherein the slits (130) include a first slit (131a) into which a first leg (220) of the first wiper arm (200) can be inserted and a second slit (131b) into which a second leg (220') of the second wiper arm (200') can be inserted. The connector (110) is compatible with a leg-added side pin arm (200) regardless of whether a leg of the leg-added side pin arm is wide or narrow and is horizontally symmetrical to be suitable for use in either a left hand drive (LHD) vehicle or a right hand drive (RHD) vehicle.
