Claims (1)

[Scope of Claim for Utility Model Registration] A reinforcing core and a reinforcing core extending from the core at a predetermined position inside the skin, which has a perforated annular shape with a hollow space in the center and is entirely bag-shaped. A core body equipped with a pair of stays is inserted and set with the stays protruding outside the skin, and a foam material is foamed inside the skin to fill the inside of the skin with the foam. In the foamed molded product with a skin, the core of the core is formed by cutting out a ring body having a shape corresponding to the skin over a certain range, and the pair of stays are extended from both ends of the core. On the other hand, an opening for inserting the core is formed in the skin, a sealing member is provided at each of a pair of opposing edges of the opening, and after the core is inserted, the foaming material is prevented from foaming. The opening in the skin is sealed by first engaging the sealing members, and the sealing member is provided with a core reinforcement that is disposed in the cut-out portion of the core and forms a ring together with the core. When the members are integrally provided and the opening is closed by the sealing member, both ends of the reinforcing member are attached to both ends of the core portion or to the upper end portions of the pair of stays extending from both ends of the core portion, respectively. A foamed molded product with a skin, which is characterized by being connected.
