摘要：
A bulldozer blade (12) is set in contact with the ground under the following conditions:
A) upward pushing force components (Fu) that push dirt upward along the blade surface are generated;
B) an upper part of the blade surface (22c) has a release surface portion in which a forward-upward release force that rolls the dirt pushed upward by (Fu) forwards is generated;
C) when downward pressing force components (Fd) are generated in response to the generated release force, a total downward pressing force (Σ Fd) is less than a total upward pushing force (Σ Fu); and
D) if each (Fu) is given a positive value and if each Fd and a reduced amount of each Fu caused when the dirt hits the release surface portion are given negative values, a value of force at an endmost section of the release surface portion is positive.
