Claim 2:
3. The molding material supply device as claimed in claim 2, wherein the exhaust hole is formed in the second discharge member,
the second discharge member comprises an opening and closing valve which opens and closes the exhaust hole,
the opening and closing valve comprises an urging member, a limiting member, and a valve body,
the urging member is disposed between the second discharge member and the valve body, and generates an urging force in a direction in which the valve body retreats with respect to the second discharge member,
the limiting member limits the valve body from retreating over a limiting position with respect to the second accommodation member, and
the valve body is retracted from the second accommodation space by the urging force to close the exhaust port when being movable with the second discharge member with respect to the second accommodation member in a front-rear direction, and resists the urging force and protrudes into the second accommodation space to open the exhaust port when staying in the limiting position and being relatively movable with respect to the second discharge member in the front-rear direction.
