Vibration isolation structure

A vibration isolation structure for a device accompanied by vibration, the vibration isolation structure comprising:

• at least one mounting structure part configured to be secured to the device and having a tabular mounting portion and a locking surface facing the tabular mounting portion, the tabular mounting portion having an insertion hole extending therethrough in a thickness direction of the tabular mounting portion and extending in a longitudinal direction of the tabular mounting portion to a side surface of the tabular mounting portion;
• at least one elastic vibration isolation member having a narrow portion narrowed by a mounting groove formed therein, the at least one elastic vibration isolation member being attached to the tabular mounting portion in such a manner that the narrow portion is inserted into the insertion hole in the longitudinal direction so that the tabular mounting portion is partially located in the mounting groove;
• and
• at least one securing member secured to the at least one mounting structure part to hold the at least one elastic vibration isolation member to the tabular mounting portion, the at least one securing member having a first body portion and a second body portion opposed to each other across the tabular mounting portion in the thickness direction, a connecting portion connecting together a first end of the first body portion and second end of the second body portion, and a locking projection projecting from the first body portion away from the tabular mounting portion, the at least one securing member being secured to the at least one mounting structure part by engagement of the locking projection with the locking surface, and the at least one securing member holding the at least one elastic vibration isolation member to the tabular mounting portion by engaging the at least one elastic vibration isolation member at least from a side thereof closer to the side surface.
