Non-adhesive type vibration reduction apparatus

A non-adhesive type vibration reduction apparatus (100) disposed between a vibration source (600) and a structure (700) spaced apart from each other in a z direction based on a 3-dimensional xyz coordinate system, and using an elastomer to reduce a vibration of the vibration source (600) comprising:

• a support (200) formed on an xy plane and coupled to a side of the vibration source (600) which is toward the structure (700);
• a body (300) including an upper side wall (310), a lower side wall (320) spaced apart from the upper side wall (310) by a predetermined distance, and a connection portion (330) connecting between the upper side wall (310) and the lower side wall (320), and coupled to a side of the structure (700) which is toward the vibration source (600);
• the elastomer (400) including a base (410) being coupled to the body (300), a first elastic portion (420) protruding and extending from the base (410) in the z direction, and a protruding portion (430) protruding from the first elastic portion (420) toward the support (200);
• a first cover disposed where the body (300) and the elastomer (400) are coupled;
• and
• a second cover disposed where the support (200) and the elastomer (400) are coupled,
• wherein an end of the support (200) is provided with a first groove (210),
• wherein the protruding portion (430) is formed to correspond to an inside shape of the first groove (210) and is inserted into the first groove (210) to be coupled thereto,
• wherein the body (300) includes a second groove (340) which is formed on an inner surface of the upper side wall (310) and the lower side wall (320),
• wherein the base (410) has an outside shape corresponding to an inside shape of the second groove (340) and is inserted into the second groove (340) to be coupled thereto,
• wherein the connection portion (330) comprises a side wall (330) enclosing the upper side wall (310) and the lower side wall (320) and a third groove (350) formed on an inner surface of the side wall (330),
• wherein the elastomer (400) further includes a side wall base (440) having an outside shape corresponding to an inside shape of the third groove (350) and the side wall base (440) is inserted into the third groove (350) to be coupled thereto.
