Opening and closing hook
A switching type hook is provided whose hook base can be made small-sized without degrading strength and durability. A stopper portion formed at an inner side of a lower end of a hook member is caused to contact directly with a side surface of a head of a bolt for fixing of the hook base so that a load applied to the hook member is born.
