PURPOSE:To provide a boot which is free from the generation of the slip between a fixed part and an installed member and possesses the high degree of sealing performance, and a metal mold for the easy blow molding of the boot with high precision and the molding method. CONSTITUTION:A boot is made of the thermoplastic elastomer, and each fixed part 3 which is closely sealed with an installed member is formed at a bellows part 2 and at both the ends of the bellows part 2, and an annular projection part 7 is formed on the outer peripheral surface of the fixed part 3. On the inner peripheral surface of the fixed part 3 corresponding to the annular projection part 7, an annular bulging-out part 8 is formed. |
