The invention relates to a solenoid actuator. Adapters (551, 552) are provided to end parts of permanent magnets (521, 522) positioned at the side where plungers (651, 652) are placed. The adapter (551) collects flux of the permanent magnets (521, 522) and the collected flux is conducted to the plungers (651, 652). The adapters (551, 552) each includes a main body part (560) configured to be plate-shaped and a base (570), the base protrudes from the main body part (560) towards the plungers (651, 652) in a stepped manner and is opposite to the plungers (651, 652) at a distance, and the distance can realize effective magnetic transmission between the base part (570) and the plungers (651, 652). The base (570) is symmetrical about a vertical line (y) vertical to a reference line (x). The reference line (x) is a straight line connected between a central axis (M) of the main body part (560) and a central axis (Q) of the base (570). |
