Snowboard binding and stopper device for snowboard binding

A snowboard binding comprising a base section attached to a snowboard and allowing a boot to be mounted thereon, a highback pivotably mounted on a rear part of the base section and capable of rotating in the longitudinal direction with respect to the base section, a strap provided in a position of the base section further frontward than the highback, and an unlockable lock mechanism for locking the highback in a state in which rearward rotation is impossible, the lock mechanism having a lock lever rotatably provided to a rear surface section of the highback and a connecting cord provided so as to span between the lock lever and the base section, and being configured so that when the lock lever is extended along the rear surface section of the highback by a rotating operation, the connecting cord is tensioned and the highback is placed in a locked state in which rearward rotation is impossible, and so that when the lock lever in the locked state is caused to project rearward from the rear surface section of the highback by the rotation operation, the connecting cord slackens and the highback is placed in an unlocked state in which rearward rotation is possible;

• the snowboard binding characterized in that an urging body for rotatably urging the highback rearward is provided to the highback, and when the lock lever of the lock mechanism is placed in an unlocked state by the rotational urging of the urging body, the highback automatically rotates rearward, and so that when the highback arrives at the rearward-rotation-limit position or near the rearward-rotation-limit position, the connecting cord is tensioned, the orientation at which the lock lever projects from the highback rear surface section is maintained, and the lock lever in the projecting orientation makes contact with the snow surface below the snowboard to bring about a slide-preventing effect.
