PURPOSE:To obtain the fixing method for the transmitter for the body of rotation whose fitting structure is simplified by using a nonmetal material for a support member and arranging the transmitter so that its signal transmission surface faces outward in a radial direction of a rotary shaft. CONSTITUTION:The transmitter 1 has its signal transmission surface 2 arranged facing outward in the radial direction of the rotary shaft 6 of the body of rotation and is fixed to the body of rotation by pressing the signal transmission surface 2 with the ring-shaped support member 11 surrounding the rotary shaft 6, and the support member 11 is made of the nonmetallic material. Therefore, antennas 7 and 9 can be arranged outside the transmitter 1 which rotates through the support member made of the nonmetallic material. Consequently, the support structure of the transmitter 1 is simplified and the fitting of the antennas is facilitated; and the structure is made compact. Further, the signal and electric power transmission efficiency between the transmitter 1 and antennas 7 and 9 is improved by using a composite material of glass and epoxy resin for the support member 11 which fixes the transmitter 1, so the interval between the both can be made large. |
