The safety valve unit is provided with a rotary barrel member (), in which a cracking-pressure adjusting portion (and) is incorporated and driven by the barrel member () in order to adjust the cracking pressure. The barrel member () has its female screw portion () threadably engaged with a male screw portion of the cracking-pressure adjusting portion () that is a movable spring support (). When the barrel member () is rotated, the spring support () is axially and linearly displaced to adjust the cracking pressure of the valve unit.
