Abstract:
This repairing-material injecting device is equipped with a check valve provided within a tubular part integrally formed by using a single material. The tubular part has a rear end provided with an attachment seat to be attached to an object to be repaired and a front end provided with a pump connection section. The check valve includes a valve seat provided at the inner periphery of the tubular part, a ball serving as a valve body, and an elastically-deformable stopper that regulates the moving distance of the ball. The inner periphery of the tubular part has an inlet surface extending toward the valve seat, and the front end of the inlet surface is provided with a stopper support section that supports the stopper. The stopper includes a ball receiving section, a plurality of engagement sections engaged with the stopper support section, and a converting mechanism that converts a force with which the ball receiving section is pressed by the ball into a force that causes the diameter of the engagement sections to increase.
