PROBLEM TO BE SOLVED: To reduce the number of pantiles to use and accordingly to reduce weight by providing an insertion piece to a back surface of a pantile main body of a slit on the head side, providing a covered piece to a surface of the pantile main body of a slit on the tail side and by increasing an area to use in the lengthy direction of the pantile. ;SOLUTION: A thin insertion piece 28 consisting of a slit on the head side, a head outer edge part 32a provided to a back surface of a pantile main body, a collar side outer edge part 32b and a mating edge part 32c of both of them is inserted below a thin covered piece 40 consisting of a slit on the tail side, a tail side outer edge part 42a provided to the surface of the pantile main body, a pantile side outer edge part 42b and a mating edge part 42c of both of them. The insertion piece 28 and the covered piece 40 are formed thin, and accordingly, thickness of both of them becomes equal to thickness of the pantile main body as they are accumulated, form the same surface as a front and back of the pantile main body, and an area of an accumulated part becomes half as large as conventionally. Consequently, an area to be used in the lengthy direction of the pantile increases, and it is possible to reduce the number of pantiles required for a unit area and to reduce the number of the pantiles to use.;COPYRIGHT: (C)1998,JPO
