Description of the Related Art Conventionally, according to Japanese Utility Model Publication No. 63-43925, two opposite sheets are partially adhered to form a large number of independent filling chambers, and a silicon gel material is filled in the filling chambers. In addition, there has been proposed a shock-absorbing shoe in which a shock absorber formed by inflating the filling chamber is bonded to a shoe upper portion fitted in a housing recess of a shoe sole provided with a housing recess on the upper surface. However, it is necessary to prepare a shock absorber in advance, provide a housing recess on the upper surface of the shoe sole, fit the shock absorber in the housing recess, and adhere the shoe sole to the upper, and the shoe must be used. There is a disadvantage that the manufacturing process becomes complicated and the cost increases.

Then Botomumo - emitted from the field emission road (B) (T 1) gate - through preparative (G 1), outsourcing - Le forming unit (K 1) and the lower cap forming part of the capsule (K 2) to a vinyl chloride resin, An outsole molding material made of a rubber-like elastic material such as EVA, thermoplastic rubber, or liquid polyurethane is injected, and the outsole (10) and the lower lid (121) of the capsule are injection-molded integrally. And at this same time or before and after this step, the third dummy - mode - field (D 3) injection gate from the injection canal (T 3) of - bets capsule lid forming portion through (G 3) (K 3)
Then, an upper lid molding material made of a rubber-like elastic material such as vinyl chloride resin, EVA, thermoplastic rubber, and liquid polyurethane is injected to integrally form the capsule upper lid (122) on the lower surface of the shell (5). Next, the bottom mold (B) is lowered, the first dummy mold (D 1 ) is extracted, and the outsole ( 1 ) is taken out.
The lower lid (121) of the capsule integrated with 0) was placed. Botomumo - field (B) the second dummy raising the - mode - field (D 2) and the combined, second dummy the lower lid of the capsule (121) - mode - field injection canal provided in (D 2) ( From T 2 ), a prescribed amount of liquid shock absorbing material (123) such as liquid silicon, liquid polyurethane, liquid rubber plastisol, etc. is injected and injected into the lower lid (121) of the capsule through the injection gate (G 2 ). After dropping the shock absorbing material (123) remaining in (G 2 ) into the lower lid (121) of the capsule, if necessary, the liquid shock absorbing material (12) injected into the lower lid (121) is used.
After partially cross-linking 3) to form a gel, the bottom mold (B) is lowered again to form the second dummy mold (D 2 ) and the third mold (D 2 ).
Dummy mold (D 3 ) is extracted, and the shock absorber (12
The bottom mold on which the outsole (10) integrated with the lower lid (121) of the capsule filled with 3) is mounted is raised again, combined with the side mold (S), and last (L).
After the upper lid (122) and the lower lid (121) of the capsule integrally formed on the lower surface of the cap (5) attached to the capsule are liquid-tightly polymerized, a mid-saw formed around the capsule (12) is formed. - Saidomo Le molding section (K 4) - outsourcing through field injection path formed in the (S) (T 4) - Le (1
A mid-sole molding material made of a rubber-like elastic material having a softer or more foamable composition than that of 0) is injected to form a mid-sole (13), and a capsule (12) is placed in the mid-sole (13). At the same time, the outsole (10) and the lower surface of the shell (5) are bonded to each other via the midsole (13). In the drawing, reference numeral 14 denotes an insole.
