1. A vehicle shovel, comprising:
an arm rotatably attached to a boom rotatably attached to a revolving body, said arm being rotatable relative to the boom on a plane perpendicular to a horizontal plane;
a bucket rotatably attached to the arm;
a tilt mechanism including a tilt axis that extends on the plane and is configured to rotatably support the bucket so as to rotate the bucket around the tilt axis;
a bucket tilt angle sensor configured to detect a tilt angle of the bucket in the direction; and
a tilt angle controller configured to control adjusting the tilt angle,
wherein the tilt angle controller adjusts the tilt angle by automatic control of the tilt mechanism so that a bucket line of the bucket becomes parallel to a target excavation surface.
