The invention relates to an improved clutch mechanism for electromechanical lock cylinders. The aim of the invention is to improve the performance of the clutch mechanism and to increase the useful life of the battery of the motor that forms part of the electromechanical cylinder of the lock. The improved clutch mechanism includes: an electromagnetic motor (2) comprising a screw spindle (3) on the shaft thereof; and a movable carriage (4) including a resilient device which is formed by two front springs (26), joined at one of the ends thereof by a common transverse portion (26') engaged in a thread root of the spindle (3), and which moves the movable carriage (4) by means of the common transverse portion (26') between a clutch-release position and a clutch-engaged position, such that, in both positions, the common transverse portion (26') pushes continuously against the spindle (3). |
