Claim Text:
1. A flat-blade wiper apparatus having an improved end cap structure, the flat-blade type wiper apparatus comprising: a wiper lip that is manufactured of an elastic material, so as to remove foreign substances on a surface of a windshield of a vehicle by contacting and sliding on the windshield; a spoiler-integrated lever that accommodates an upper part of the wiper lip and prevents the wiper lip from floating on a glass surface of the windshield while the vehicle is moving at a high speed; a vertebra that is assembled in the spoiler-integrated lever and elastically supports the wiper lip on the windshield; and an end cap that couples to one end of the vertebra and prevents the wiper lip from slipping in a direction of a length of the vertebra, wherein a cap fixing hole is disposed at one end of the vertebra in the direction of the length of the vertebra and passes through an upper surface and a lower surface of the vertebra; a first stopper protrudes from a ceiling surface of the end cap in a downward direction and couples to the cap fixing hole; a second stopper protrudes from a sidewall of the end cap toward the wiper lip, and prevents the wiper lip from slipping by being accommodated in a coupling groove that is formed in the wiper lip; and an auxiliary stopper that is disposed in a periphery of the first stopper in the direction of the length of the vertebra from the first stopper to a center of the vertebra, and that is smaller than the first stopper.
