PROBLEM TO BE SOLVED: To enable transmission of torque surely at all times from a rotor to a drive shaft even under a server environment of temperature change in the rotary solenoid device, so that the difference in thermal expansion/ contraction amounts between the rotor and a rotor support can be damped. SOLUTION: This rotary solenoid device mounts a rotor 13 constituted by a hollow cylindrical permanent magnet to be fitted to a rotor support 11 formed in a drive shaft 5. The rotor 13 is slidably fitted to the rotor support 11, and it is provided with a thrust receiving part 11a supporting axially at one end face of this rotor 13, and an elastic member 20 compressively holding the rotor 13 with elastic force relating to this thrust receiving part 11a is secured to the rotor support 11.
