Abstract
A linear solenoid is disclosed that includes a coil that generates magnetic force due to transmission of current therethrough. The linear solenoid also includes a plunger with an end face, a stator that movably supports the plunger, and a yoke including a bottom face. Furthermore, a biasing member is included that biases the plunger in a first direction along the axis. The stator magnetically attracts the plunger when current is transmitted through the coil so as to move the plunger in a second direction along the axis opposite to the first direction. Also, when current transmission through the coil is stopped, the biasing member biases the plunger to abut the bottom face of the yoke at least one abutted portion. Also a non-contact portion is included between the abutted portions where the plunger and the stator are spaced away from each other in the direction of the axis.
