<P>PROBLEM TO BE SOLVED: To provide an in-vehicle power supply device which can withstand a severe environment of vibration or the like. <P>SOLUTION: A DC-DC converter 130 and a plate body 161 are fixed (disabled from moving relatively) with a bolt as illustrated in Fig.6(a). As a result, when the plate body 161 is deformed minutely in accordance with vibration, the DC-DC converter 130 is vibrated minutely with the vicinity of a weak point S1 in the plate body 161 as a fulcrum. Furthermore, as illustrated in Fig.6(b), a low voltage battery 140 does not include a substantial fixed structure in such a degree as to disable relative movement and is clamped by a fastening force generated by a mounting implement which is configured independent of the low voltage battery, namely, in a mounting implement 163 and the plate body 161. The separation of the low voltage battery from the plate body 161 is limited by this fastening force so that, upon receipt of an impulse or vibration, minute free movement (sliding or deviation due to vibration) is incurred in the low voltage battery 140 by friction or minute elastic deformation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
