<p>Provided is an in-vehicle power source device capable of withstanding severe conditions such as vibrations. As illustrated in figure 6(a), a DC-DC converter (130) and a plate body (161) are secured (incapable of relative movement) by a bolt. Therefore, when the plate body (161) deforms slightly due to vibration, the DC-DC converter (130) ends up vibrating slightly with the vicinity of the weak point (S1) on the plate body (161) functioning as the pivot point. Moreover, as illustrated in figure 6(b), a low-voltage battery (140) does not have a substantive secured structure such that the low-voltage battery (140) is incapable of relative movement. Additionally, the low-voltage battery (140) is held by means of the clamping force generated by means of the plate body (161) and an attachment tool that is independent from the low-voltage battery, in other words, attachment tool (163). The low-voltage battery is prevented from separating from the plate body (161) by means of said clamping force. As a consequence, when the low-voltage battery (140) is subjected to impact or vibration, a minute free movement (such as sliding and misalignments due to the vibration) occurs due to friction and minute elastic deformation.</p> |
