Abstract
Official abstract text for this publication.
An air pump device includes an electric pump unit including a pump mechanism and a motor configured to drive the pump mechanism, a case housing the electric pump unit, and a vibration-proof member interposed between the electric pump unit and the case. The vibration-proof member is a plate-shaped member made of an elastic resin material and is wound around the electric pump unit to wrap the electric pump unit therein. A part of the vibration-proof member is sandwiched between the electric pump unit and one of facing surfaces that are inner surfaces of the case and face each other inside the case. Another part of the vibration-proof member is sandwiched between the electric pump unit and the other one of the facing surfaces.
First claim
Opening claim text (preview).
What is claimed is: 1. An air pump device comprising: an electric pump unit including a pump mechanism and a motor configured to drive the pump mechanism; a case housing the electric pump unit; and a vibration-proof member interposed between the electric pump unit and the case, wherein the vibration-proof member is made of an elastic resin material and is wound around the electric pump unit to wrap the electric pump unit therein, a part of the vibration-proof member is sandwiched between the electric pump unit and one of a plurality of facing surfaces that are inner surfaces of the case and face each other inside the case, another part of the vibration-proof member is sandwiched between the electric pump unit and an other one of the plurality of facing surfaces, the case has a divided structure including a first divided case and a second divided case, the vibration-proof member includes a sandwiched portion extending in a joint portion of the first divided case and the second divided case and interposed between the first divided case and the second divided case, the case has a structure in which the first divided case and the second divided case are joined to each other through engagement between a locking piece protruding from one of the first divided case and the second divided case and a locked portion provided on an outer surface of the other one of the first divided case and the second divided case, and the sandwiched portion of the vibration-proof member has a through hole through which the locking piece is inserted. 2. The air pump device according to claim 1 , wherein the vibration-proof member has a slit extending in a predetermined pattern. 3. A seat apparatus comprising: an airbag disposed on an inner side of a seat; and the air pump device according to claim 1 that pressure-feeds air to the airbag. 4. The air pump device according to claim 1 , wherein the sandwiched portion is compressed directly between the first divided case and the second divided case.
