Claim:
A mounting bracket structure comprising: a base part; and an attachment part having a mounting bracket that is fastened with a fasten member to the base part; wherein the mounting bracket, in which a slit extending in a direction intersecting a loading direction of a rupture load is formed, includes a rigid portion disposed at one side of the slit and a breakable portion disposed at the other side of the slit which is breakable because of the presence of the fastening member, wherein the slit has a width so as to enable the fastening member to pass therethrough with the breakable portion in an unbroken state, and when a predetermined rupture load is applied to the mounting bracket of the attachment part, a rupture is developed in the mounting bracket, so that the attachment part is separated from the base portion by this rupture; wherein the slit includes an opening portion at one end with the breakable portion in the unbroken state.
