PROBLEM TO BE SOLVED: To provide a fluid controller which employs a motor and prevents the motor from projecting to a body. SOLUTION: A transmission means 10 for converting the rotation of a motor 9 into linear motion to be transmitted to a stem 8 includes a ball bearing 21 fixed to the stem 8 and an eccentric shaft 22 fixed to an output shaft 9a in the motor 9 and formed so as to come into contact with the ball bearing 21 from above. When a radial distance R from an axial core of the output shaft 9a to a contact position of a large ball 25 and an outer peripheral edge of the undersurface 22a of an eccentric shaft 22 is short, the whole of the ball bearing 21 is situated relatively at an upper side. When a radial distance R from the axial core of the output shaft 9a to the outer peripheral edge of the undersurface 22a of the eccentric shaft 22 becomes long, the whole of the ball bearing 21 is moved downward by a distance D as shown by an arrow.
