Claims

[Scope of utility model registration request]

In a wiper shaft that penetrates from the inside of the machine body toward the outside so as to be rotatable with respect to a sleeve that is integrally fixed to the machine body side, an engagement groove is formed in the sleeve penetrating portion of the wiper shaft, To prevent the wiper shaft from coming off by fitting the stopper ring into the engagement groove,
The stopper ring is formed using a ring-shaped elastic ring that elastically fits into the engagement groove and has an open end that is separated so that the ring can be forcefully expanded. A stop ring structure for a wiper shaft, characterized in that the end portion is retracted toward the outer diameter side so that the ring opening end is separated from the outer peripheral surface of the wiper shaft.
