PROBLEM TO BE SOLVED: To provide a linear solenoid which suppresses the lowering of magnetic attraction force of a stator core.SOLUTION: An O-ring 60 is provided between a magnetic interrupting portion 45 of a stator core 40 and a bobbin 21. The O-ring 60 contacts with both of an outer wall surface 56 of the magnetic interrupting portion 45 and an inner wall surface 57 of the bobbin 21 over the whole circumference. In this structure, foreign substances entering the inside through a clearance 51, a breath groove 52, and a clearance 53 are prevented from depositting on the outer wall surface 56 of the magnetic interrupting portion 45 or adhering to the inner wall surface 57 of the bobbin 21 so as to bridge a guiding portion 41 and a sucking portion 42. Therefore, the increase of magnetic flux among moving between the guiding portion 41 and the sucking portion 42 without a plunger 30 can be avoided, and the lowering of magnetic attraction force of the stator core 40 can be suppressed. |
