PROBLEM TO BE SOLVED: To improve efficiency in the bonding work of a spacer and to facilitate recycling about a sleeve partition 1 of a seat for a train obtained by insert-holding the spacer between an inner side case 3 and an outer side case 4 made of synthetic resin and bonding it. SOLUTION: The sleeve partition 1 of the seat for the train has an uneven sheet 7 of a thermally-molded product which is made of the same kind of synthetic resin as the inner side case 3 and the outer side case 4 and where large projecting parts 10 and small projecting parts 11 are formed adjacently to each other in the alternate state of a front surface and a rear surface. As to the large projecting parts and the small projecting parts, when setting respective projecting heights to be H<SB>1</SB>and H<SB>2</SB>, top surface areas to be S<SB>1</SB>and S<SB>2</SB>, forming densities to be D<SB>1</SB>and D<SB>2</SB>, and the inclinations of (draft) of peripheral side face to beθ<SB>1</SB>andθ<SB>2</SB>, H<SB>1</SB>/H<SB>2</SB>=0.5 to 2.0, S<SB>2</SB>/S<SB>1</SB>=0.3 to 0.8, D<SB>1</SB>=4 to 10 pieces/100 cm<SP>2</SP>, D<SB>2</SB>=4 to 10 pieces/100 cm<SP>2</SP>,θ<SB>1</SB>=5 to 25°,θ<SB>2</SB>=5 to 25°are satisfied, and the side of the large projecting parts 10 is on the side of a mold recessed form when performing thermal forming.
