PROBLEM TO BE SOLVED: To provide a motor driving valve capable of downsizing a motor.SOLUTION: In a motor driving valve 10, a linear motion shaft 50 including a valve body 31 on a tip part receives driving force from a stepping motor 13 and is driven in a valve opening direction and a valve closing direction. The leaner motion shaft 50 includes: a side protrusion piece 52 protruded to a side, and an assist spring 40 is inserted into a portion closer to a tip side than the side protrusion part 52. The assist spring 40, when a valve state is shifted from a valve opened state to a valve closed state, is compressed and deformed between the side protrusion piece 52 and a main base 21 and energizes the valve body 31 in a valve opening direction in the valve closed state. |
