Title:
CYLINDER LOCK DEVICE
Document Type and Number:
Japanese Patent JPS61223372
Kind Code:
A
Abstract:
PURPOSE:To eliminate the need to use a high oil pressure, by providing an electromagnet device, which produces a magnetic repulsion force in a direction, in which it is separated from a plunger, when energized, and a resilient body which deviates the electromagnet device toward the plunger. CONSTITUTION:An electromagnet device 20 is formed with a yoke 15, a coil 19, and a shoe 21. A resilient body 14 is inserted between the rigid yoke 15, disposed in a state in that pole-faces 17 are positioned facing each other, and a rigid housing 10 in a state in that it is compressed against its resilient force. Thus, the resilient force of the resilient body 14 is transmitted to the outer peripheral surface of a plunger 4 through the yoke 15 and the shoe 21, an extremely high pressure is exerted between the plunger 4 and the shoe 21, and an extremely high drag is exerted when the plunger 4 is about to move from the shoe 21.
