摘要： PROBLEM TO BE SOLVED: To provide a sealing structure of a hole capable of improving load for pulling out a plug member and improving durability of a sealing function.
SOLUTION: In this sealing structure of the hole constituted in such a way that the plug member 23 constituted to have diameter being smaller than diameter of an opening part 21a and larger than diameter of a hole inward part 21b and made of a material more easily deformable plastically than that of a shaft 19 is inserted into the hole 21 formed in the shaft 19 being a member arranged in an automatic transmission and forming a stepped part 21c in which the opening part 21a has larger diameter than that of the hole inward part 21b, the plug member 23 is abutted on the stepped part 21c, is pressed against it, and is plastically deformed, a part of the plug member 23 is pushed out in the hole inward part 21b, and a part of its outside diameter part comes into close-contact with the opening part 21a and is sealed, a filling part 21d having larger diameter than that of an opening end of the opening part 21a is formed in the vicinity of the stepped part 21c of an opening part inward part being more inward than the opening end of the opening part 21a.
