Zusammenfassung:	PROBLEM TO BE SOLVED: To mold a lamp part for a vehicle having an undercut part without complicating a mold. SOLUTION: This molding machine for molding the lamp part for the vehicle is equipped with the ejector plate 40 positioned on the side opposite to a fixed mold and capable of moving a mold clamping/opening direction. The mold surface corresponding to the undercut part of a movable mold 30 is formed by a push-up block 32, the push-up block 32 is integrally fixed to the leading end of a push-up pin 42, the push-up pin 42 is revolvably inserted in the insertion hole 34 to be positioned in the ejector plate 40, a gap enabling the tilting of the push-up pin 42 is formed to the insertion hole 34, the lamp part for the vehicle is released from the movable mold when it is released from the movable mold and the mold surface of the push-up block is pressed in the direction crossing the mold clamping/opening direction by the inclined surface of the undercut part by the further movement of the lamp part for the vehicle therefrom to release the push-up block from the undercut part by the revolution of the push-up pin integrated with the push-up block with respect to the ejector plate.
