A piezoelectric single crystal device is provided exhibiting excellent piezoelectric properties, within a specific high-temperature range of Trrt° C. to (Trt−20)° C., where Trt represents a transformation temperature between a pseudocubic system and a tetragonal system. Specifically, the piezoelectric single crystal device is composed of a single crystal having a composition represented by [Pb(Mg,Nb)O3](1-X)·[PbTiO3](X), where X is within the range of 0.26 to 0.29 and having a complex perovskite structure, wherein a specific inductive capacity at 25° C. is 5,000 or more, and a specific inductive capacity at the transformation temperature between a pseudocubic system and a tetragonal system of the above-described single crystal is 2.5 times or more larger than the specific inductive capacity at 25° C.

An inexpensive piezoelectric single-crystal device being excellent in the piezoelectric characteristics and having a complex perovskite structure can be provided by adding a specific additive to a lead magnesium niobate-lead titanate (PMN-PT) single crystal or a lead zinc niobate-lead titanate (PZN-PT or PZNT) single crystal. Specifically, the piezoelectric single crystal has a complex perovskite structure and is formed of a composition containing 35 to 98 mol % lead magnesium niobate [Pb(Mg1/3Nb2/3)O3] or lead zinc niobate [Pb(Zn1/3Nb2/3)O3], 0.1 to 64.9 mol % lead titanate [PbTiO3], and 0.05 to 30 mol % lead indium niobate [Pb(In1/2Nb1/2)O3] wherein calcium is substituted for 0.05 to 10 mol % lead in the composition.

A steering apparatus support structure includes a steering support member extending transversely in a vehicle body and secured to rigid side components of the vehicle body which are likely free from deformation during a frontal end collision and a support bracket device secured to and supported by the steering support member for supporting forward and rearward portions of the steering column. The support bracket device is releasably linked to a vehicle body part which can be deformed backward during a frontal end collision, and the vehicle body part is allowed to be disconnected from the support bracket device when backward deformation is caused in the vehicle body part.
