The antenna 26 is inserted and locked. A groove-shaped concave portion formed so as to be possible is a solder for fixing the antenna 26 on the meter substrate 23. According to the present embodiment, since the antenna 26 can be inserted and locked by the recess 32, the dead corresponding to the height of the antenna 26 (corresponding to the diameter of the antenna 26) on the fixed surface of the meter substrate 23 and the lower housing 1. There is no space, and the whole can be made compact. Other configurations, operation examples, and effects are the same as in the case of the first embodiment, so description thereof will be omitted.

１と同様の作用効果が得られる。Example 6. FIG. 8 is a vertical sectional view showing a state in which the antenna 26 according to one embodiment of the present invention is wound plural times and provided in the recess 36 of the lower housing 1. FIG. 9 is a side view of the recess 36 in FIG. In the drawing, reference numeral 36 denotes a concave portion which is an outer peripheral edge of the lower housing 1 and is formed on the meter substrate 23 side so that the linear antenna 26 can be wound plural times. According to the present embodiment, since the antenna 26 can be wound plural times by the concave portion 36, the length of the loop path of the antenna 26 can be arbitrarily and easily ensured, and moreover, the fixed surface between the meter substrate 23 and the lower housing 1 can be secured. There is no dead space corresponding to the height of the antenna 26, and the entire structure can be made compact. Other configurations, operation examples, and effects are the same as in the case of the first embodiment, so description thereof will be omitted. Also, when the antenna is insert-molded in the meter housing, the same operational effect as that of the first embodiment can be obtained.
