Abstract
In a cylinder for locks having an outer barrel and an inner cam with a keyhole. In order to lock the movement of the inner cam, a pin is provided in the outer barrel and the pin is engaged into a hole defined in the inner cam to lock the inner cam. The pin is urged by a spring so as to eject the pin from the hole and the pin is inserted into the hole by a driving mechanism utilizing a manual force. The engaging state of the pin with respect to the hole is held by a hold mechanism without any electric power consumption. The hold mechanism is responsive to an electric signal to release the engaging state between the pin and the hole.
