<P>PROBLEM TO BE SOLVED: To improve sitting and riding comfort on a seat and to reduce pressure to femoral regions. <P>SOLUTION: A slit 28 extending in the width direction is arranged in the front edge side of a pad front surface in a sitting portion 12. The slit 28 is formed in an attitude tilting backward towards the pad back surface side from the pad front surface, and a front edge part 30 on the front side beyond the slit 28 is formed of a foam body with lower hardness than that of a sitting portion body 32 on the back side. In a molding die 50, a sitting portion molding region 64 of a lower die 52 is divided, by a separation board 78 protruded on a cavity bottom face 76, into a front edge molding region 80 for molding the front edge part 30 and a body part molding region 82 for molding the sitting portion 32, and the separation board 78 is formed in an attitude tilting backward toward the upper side from the cavity bottom face 76. <P>COPYRIGHT: (C)2012,JPO&INPIT |
