Title:
AIR SPRING LOCKING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/138141
Kind Code:
A1
Abstract:
A seated part 13 of an air spring 10 has a first contact part 19, a first opposing surface 20, and a shaft part 14. A spring support part 30 had a second contact part 31 that comes into contact with the first contact part 19 in a seated state, a second opposing surface 32 that is set apart from and that opposes the first opposing surface 20, a shaft insertion hole 33, and a shaft-movement-restricting part 34 protruding from the second opposing surface 32 so as to section off a shaft insertion space 35 that communicates with the shaft insertion hole 33. The shaft part 14 is inserted through the shaft insertion hole 33 and the shaft insertion space 35 in the seated state. The tip end of the shaft part 14, which withdraws from the shaft insertion hole 33 due to the rising of an upper structure from the seated state, moves through the shaft insertion space 35. The tip end of the shaft part 14 withdrawn from the shaft insertion hole 33 enters the shaft insertion hole 33 from the shaft insertion space 35 due to the lowering of the upper structure to the seated state.
