ELECTRODYNAMIC EXCITER AND VEHICLE LAMP FITTING EMPLOYING SAME

WIPO Patent Application WO/2013/084639

A1

The purpose is to enhance the vibration characteristics in an electrodynamic exciter, and to ensure ample support strength of the magnetic circuit unit. The configuration is provided with three flexible arms (54) extending in the same circumferential direction, as a suspension (50) for supporting the magnetic circuit unit in displaceable fashion in the vertical direction with respect to a coil support member (40). This assures sufficient length of each of the flexible arms (54), enhancing the vibration characteristics. Next, arm insertion slots (40g) having approximately the same vertical width as the flexible arms (54) are formed at three locations in the circumferential direction in the coil support member (40). The distal end (54a) of each flexible arm (54) is then inserted into the arm insertion slot (40g), doing so in the aforementioned same circumferential direction, causing a barb (54a1) to engage an engaging part (40f1) and detain the flexible arm (54). The magnetic circuit unit is thereby supported over a certain length in the circumferential direction at the distal ends (54a) of the flexible arms (54), enhancing the support strength thereof.
