Claims

[Claims for Utility Model Registration] (1) A coil bobbin is housed in a case whose bottom is closed, and two coils are wound around the coil bobbin in directions orthogonal to each other to form a cross coil. A cross coil is formed by disposing a magnet rotor inside so as to be freely rotatable about a rotation axis, and the lower end of this movement is loosely fitted into an opening formed in a wiring board that conducts electricity to each of the coils. A cross-coil type indicator, characterized in that a protrusion is formed at the lower end of the coil bobbin, the protrusion coming into contact with the bottom plate of the case body. (2) A coil bobbin is housed in a case body with a closed bottom, and two coils are wound around this coil bobbin in directions orthogonal to each other to form a cross coil, and a magnetic rotor is attached to the rotating shaft inside this cross coil. In a cross-coil type indicator in which a movement is arranged horizontally so as to be freely rotatable around the case, and the lower end of this movement is loosely fitted into an opening formed in a wiring board that conducts electricity to each of the coils, the above-mentioned case A cross-coil type indicator characterized by having multiple small holes drilled in the bottom plate of the body. (3) A coil bobbin is housed in a case body with a closed bottom, and two coils are wound around this coil bobbin in directions orthogonal to each other to form a cross coil, and a magnetic rotor is attached to the rotating shaft inside this cross coil. In a cross-coil type indicating instrument, the movement is configured such that the lower end of the movement is loosely fitted into an opening formed in a wiring board for energizing each of the above-mentioned coils, the above-mentioned case body A cross-coil type indicator characterized by having multiple reinforcing ribs formed on the bottom plate.
