Abstract
A head light module includes: a lamp disposed to irradiate light; a shield disposed to be rotatable about a rotating pin so as to selectively block a light path of a portion of the light irradiated from the lamp; a plunger disposed to be moved in a longitudinal direction thereof in order to push or pull one side of the shield; a compressive roll pad disposed so that an outer circumferential surface thereof is in contact with the plunger, rotated in accordance with a forward and rearward movement of the plunger, and compressed by the plunger or returns back to an original shape thereof when the plunger is moved forward or rearward; and an actuator which moves the plunger forward or rearward so that the shield selectively blocks the light path of a portion of the light irradiated from the lamp.
