PROBLEM TO BE SOLVED: To easily suppress valve axial enlargement in an electromagnetically driven valve. SOLUTION: This electromagnetically driven valve is designed by arranging an armature stem guide 36 to a lower core 24 on a valve 6 side. An armature stem 32 is certainly supported by the armature stem guide 36, therefore, a bearing member such as a bush is not required to provide to an upper core 22 on a side opposite to a valve 6, and the linear displacement detecting coil 34a of a lift amount sensor 34 can be arranged in a passing hole 22a in the upper core 22. The base part 44a of a lower retainer 44 is arranged on the inner side of the base end of a lower spring 46, and a part of an upper retainer 38 is arranged in a storage space 44b arranged on the inner side of the base part 44a, thereby, a valve axial size can be shortened. A lash adjuster 48 is also stored in the storage space 44b, therefore, valve axial enlargement in the electromagnetically driven valve can be easily suppressed. COPYRIGHT: (C)2006,JPO&NCIPI
