Claims

[Claims for Utility Model Registration] (1) A yoke, a coil housed in the yoke, a plunger that is attracted into the coil when the coil is energized, and a plunger that protrudes when the coil is de-energized. In a solenoid equipped with a return spring for returning to a return position, a high magnetic resistance portion provided on a part of the yoke, one arm facing the plunger and the other arm facing the high magnetic resistance portion. a double-armed lever which is pivotally connected to said yoke, said other arm being made of a magnetic material, and said other arm being magnetically coupled to said yoke at said pivoting portion; a pressing means for pressing one arm of the plunger toward the plunger; and a locking portion provided on the plunger that engages with the one arm to prevent movement of the plunger in the attraction direction when the coil is not energized. A solenoid comprising: when the coil is energized, the other arm is attracted toward the high magnetic resistance portion, causing the one arm to disengage from the locking portion. (2) The solenoid according to claim 1, wherein the high magnetic resistance portion is an opening. (3) The solenoid according to claim 1, wherein the high magnetic resistance portion is a thin portion with a recess formed therein. (4) The solenoid according to claim 1, wherein the high magnetic resistance portion is a notch. (5) The solenoid according to claim 1 of the utility model registration claim, in which the high magnetic resistance portion is formed on the top surface of the yoke. (6) Utility model registration claim 1, in which the other arm of the dual-arm lever is magnetically coupled to the yoke by forming a pivoting device for pivotally connecting the dual-arm lever to the yoke from a magnetic material. Solenoid. (7) Utility model registration claim No. 1 in which the other arm of the double-arm lever is magnetically coupled to the yoke by bringing the other arm close to the yoke at the pivot point of the double-arm lever to the yoke. The solenoid described in item 1. (8) The solenoid according to claim 1, wherein the locking portion is a protrusion provided on the peripheral surface of the plunger. (9) The solenoid according to claim 8 of the utility model registration, wherein the protruding portion is annular. (10) The solenoid according to claim 8 or 9, wherein the protruding portion is a spring holder for a return spring. 〓(11)１１〓 The locking portion is a recess provided on the circumferential surface of the plunger, and one arm of the double-arm lever has a protruding portion into the recess, according to claim 1 of the utility model registration claim. Solenoid listed. (12)12 The solenoid according to claim 11, wherein the recess is annular.
