Abstract
A cross coil type indicating instrument including a coil bobbin having first and second chambers separately formed inside, a rotary shaft to which a magnet rotor and a rotary gear are secured in the first chamber, and an eccentric shaft to which a transmission gear is secured in the second chamber so as to engage with the rotary gear. A pointer is secured to an end portion of the eccentric shaft. Further, the coil bobbin has a coil winding portion with a flat surface outside where the first chamber is formed, and two coils are wound on the coil winding portion in such a manner that they are perpendicular to each other. Hence, the coils are guided linearly when wound on the coil winding portion.
