A dual plunger solenoid valve comprising: first and second valve bodies (2 1, 2 2), each being laterally disposed in a side-by-side positional relationship; first and second moving cores (3 1, 3 2), each having connected to one end thereof the first and second valve bodies, respectively; first and second guide tubes (4 1, 4 2), each having slidably inserted thereinto the first and second moving cores, respectively; first and second stationary cores (5 1, 5 2), each being disposed in an inner circumference of an opposite end portion of the first and second guide tubes, respectively, so as to face an opposite end of the first and second moving cores; first and second valve springs (6 1, 6 2) to urge the first and second moving cores in a direction away from the first and second stationary cores, respectively; first and second electromagnetic coils (7 1, 7 2) disposed to enclose the first and second guide tubes, respectively; and a common magnetic plate (8 1) disposed on the opposite ends of both the first and second guide tubes, whereby the first and second moving cores are sucked to each of the first and second stationary cores by a magnetic force transmitted through the common magnetic plate to the first and second stationary cores due to electric charging to the first and second electromagnetic coils, wherein each of the first and second guide tubes has a caulked portion formed to fix in position each of the first and second stationary cores by engaging the caulked portion with a recessed groove formed on on an outer periphery of the first and second stationary cores, respectively, such that, in a state in which the first and second stationary cores are fixed in position by each of the first and second caulked portions, those surfaces of the first and second stationary cores which faces the magnetic plate are either flush with, or are protruding beyond, the opposite ends of the first and second guide tubes, whereby, by thus disposing the magnetic plate on the opposite ends of the first and second guide tubes, those surfaces of each of the stationary cores which faces the magnetic plate are in contact with the magnetic plate. first and second valve bodies (2 1, 2 2), each being laterally disposed in a side-by-side positional relationship; first and second moving cores (3 1, 3 2), each having connected to one end thereof the first and second valve bodies, respectively; first and second guide tubes (4 1, 4 2), each having slidably inserted thereinto the first and second moving cores, respectively; first and second stationary cores (5 1, 5 2), each being disposed in an inner circumference of an opposite end portion of the first and second guide tubes, respectively, so as to face an opposite end of the first and second moving cores; first and second valve springs (6 1, 6 2) to urge the first and second moving cores in a direction away from the first and second stationary cores, respectively; first and second electromagnetic coils (7 1, 7 2) disposed to enclose the first and second guide tubes, respectively; and a common magnetic plate (8 1) disposed on the opposite ends of both the first and second guide tubes, whereby the first and second moving cores are sucked to each of the first and second stationary cores by a magnetic force transmitted through the common magnetic plate to the first and second stationary cores due to electric charging to the first and second electromagnetic coils, wherein each of the first and second guide tubes has a caulked portion formed to fix in position each of the first and second stationary cores by engaging the caulked portion with a recessed groove formed on on an outer periphery of the first and second stationary cores, respectively, such that, in a state in which the first and second stationary cores are fixed in position by each of the first and second caulked portions, those surfaces of the first and second stationary cores which faces the magnetic plate are either flush with, or are protruding beyond, the opposite ends of the first and second guide tubes, whereby, by thus disposing the magnetic plate on the opposite ends of the first and second guide tubes, those surfaces of each of the stationary cores which faces the magnetic plate are in contact with the magnetic plate.
