<p>PROBLEM TO BE SOLVED: To provide a magnetic lock device and a parking device including the magnetic lock device capable of restricting power consumption and increasing magnetic efficiency while restricting a large-sized formation of the device.SOLUTION: A lock shaft 21 and a shaft member 31 are locked under attraction between a permanent magnet 33 and a flange part 35a not to be retracted from a piston rod 12 when a coil 34 is not electrically energized. Accordingly, power consumption can be restricted. In addition, a large-diameter part 23 of the lock shaft 21 is inserted into a concavity 310 of the shaft member 31 (the permanent magnet 33 is positioned to enclose the outer periphery of the large-diameter part 23). With this arrangement as above, even if the lock shaft 21 is loosened in its radial direction, the looseness can be accommodated by a clearance between the outer circumferential surface of the large-diameter part 23 and the inner circumferential surface of the permanent magnet 33 and magnetic efficiency can be improved while a large-sized formation of the device is restricted.</p> |
