Claims

[Scope of utility model registration request]

A governor body that rotates at a rotational speed that corresponds to the vehicle speed, a governor weight that is attached to a circumferential shaft provided on the governor body and that can move circumferentially in accordance with the rotational speed, and a governor weight that is linked to the movement of the governor weight. A governor valve device for an automatic transmission, which includes a governor valve that opens and closes with a pusher, and a snap spring that is provided at the tip of the outer circumferential shaft and prevents the governor weight from separating in the outer circumferential direction, which rotates integrally with the governor body. A governor valve device for an automatic transmission, characterized in that a stopper surface is provided on a portion thereof to prevent the governor weight from coming off the circumferential axis when the snap spring comes off the circumferential axis. .
