PROBLEM TO BE SOLVED: To enable easy fitting and positioning of a vibration exciter to an instrument.SOLUTION: There is provided a fitting structure having a vibration exciter body 41 of a vibration exciter 40 fixed to a housing 11 of an instrument via a support part 50, where the support part includes a positioning engaging part 56A that screws a fixing screw 91 from a contact surface 54a side of the support part with which the vibration exciter body is in contact, and engages with the vibration exciter body while the vibration exciter body is in surface contact with the contact surface to regulate the movement of the vibration exciter body in a direction along the contact surface. The vibration exciter body has a head insertion hole part 436A having the dimension of the inner diameter larger than that of the head of the fixing screw, and a shank insertion hole part 436B having the dimension of the inner diameter smaller than that of the head of the fixing screw and larger than that of the shank of the fixing screw, which are formed in continuation. After the head of the fixing screw is inserted into the head insertion hole part, the vibration exciter body is moved with respect to the support part in the direction along the contact surface to insert the fixing screw into the shank insertion hole part and engage the positioning engaging part with the vibration exciter body.SELECTED DRAWING: Figure 3 |
