Support member and catalyst converter support structure

A catalyst converter support structure comprising:

• a catalyst converter;
• and
• a support member configured to support the catalyst converter on a vehicle, wherein the catalyst converter includes an attachment portion having a through hole, the support member includes
• a pair of first support members formed of an elastic material and provided to sandwich and support the attachment portion, one of the first support members being in contact with a vehicle side, and
• a second support member provided between the pair of first support members, formed of an elastic material separately from the first support members, and configured to support an inner peripheral side of the through hole,
• the support member has a groove portion which is formed in an entire outer periphery thereof and into which the attachment portion is inserted,
• the attachment portion is provided at an end portion of a plate spring member having another end portion fixed to the catalyst converter,
• vibration applied to the catalyst converter is absorbed by elastic deformation of the plate spring member, vibration in a thickness direction of the plate spring member is absorbed by elastic deformation of the first support members that vertically sandwich the end portion of the plate spring member, and vibration in a longitudinal direction of the plate spring member is absorbed by elastic deformation of the second support member disposed on the inner peripheral side of the through hole provided at the end portion of the plate spring member, and
• a predetermined gap is provided between the second support member and an inner peripheral surface of the through hole.
