In this report, results of the vibrational analysis in a bal-anced states and various unbalanced states for 300Hz and 120Hz tuning fork oscillators by using in-plane method by speckle pat-tern are given. Especially, the U-shaped part near the fixed part is analyzed. In a balanced state, the vibrational amplitude decreases as the point approaches to the fixed point, and the direction of the vibrations is almost perpendicular to the fork and is symmetric with respect to the fixed point. In unbalanced states, the direction of the vibrations near the fixed point turns to the direction along the fork. The amplitude is much larger thean that in a balanced state even near the fixed point and is independent of the distance from the fixed point.
