An electromagnetic solenoid, comprising: a cylindrical coil portion; a fixing portion (12, 42, 52) fixed inside the coil portion; a plunger extending in an axial direction of the coil portion; and a movable yoke to which the plunger is fixed, wherein the movable yoke is movably installed inside the coil portion in the axial direction of the coil portion, configured for advancing to be separated from the fixing portion (12, 42, 52) together with the plunger due to excitation of the coil portion, and configured for retreating to approach the fixing portion together (12, 42, 52) with the plunger due to demagnetization of the coil portion, wherein the movable yoke has a shock absorbing means for absorbing a shock when the plunger retreats together with the movable yoke and the movable yoke collides with the fixing portion (12, 42, 52), wherein the shock absorbing means has: a bearing member installed in an accommodating portion formed in the movable yoke for relatively moving with respect to the movable yoke in the axial direction and having a protruding portion protruding from an end portion of the movable yoke; and a spring installed between the bearing member and the plunger for biasing the bearing member to a surface formed in the accommodating portion, and when the plunger retreats together with the movable yoke and the protruding portion collides with the fixing portion (12, 42, 52), the movable yoke temporarily retreats against a biasing force of the spring to return to a predetermined position; characterized in that a cushioning material is installed between the bearing member and the plunger, wherein the cushioning material is configured for absorbing a shock between the bearing member and the plunger which is moved together with the movable yoke when the movable yoke retreats against the biasing force of the spring, and wherein the cushioning material is attached to an attachment portion of the bearing member and movable with the bearing member with respect to the movable yoke in the axial direction. a cylindrical coil portion; a fixing portion (12, 42, 52) fixed inside the coil portion; a plunger extending in an axial direction of the coil portion; and a movable yoke to which the plunger is fixed, wherein the movable yoke is movably installed inside the coil portion in the axial direction of the coil portion, configured for advancing to be separated from the fixing portion (12, 42, 52) together with the plunger due to excitation of the coil portion, and configured for retreating to approach the fixing portion together (12, 42, 52) with the plunger due to demagnetization of the coil portion, wherein the movable yoke has a shock absorbing means for absorbing a shock when the plunger retreats together with the movable yoke and the movable yoke collides with the fixing portion (12, 42, 52), wherein the shock absorbing means has: a bearing member installed in an accommodating portion formed in the movable yoke for relatively moving with respect to the movable yoke in the axial direction and having a protruding portion protruding from an end portion of the movable yoke;
