Suspension arm attachment structure

A suspension arm attachment structure comprising:

• a suspension arm adapted to be mounted to a vehicle body and connected to a knuckle supporting a vehicle wheel;
• a tubular attachment part provided to the suspension arm and supported so as to be swingable toward the vehicle body;
• a tubular vibration-damping bush fitted in the tubular attachment part and adapted to be mounted to the vehicle body via a core member;
• and
• a stopper member for preventing axial movement of the tubular attachment part, wherein the stopper member comprises:
• a pair of opposite walls provided in opposed relation to end surfaces of the vibration-damping bush, said opposite end walls comprising a first end wall and a second end wall;
• a connection part integrally connecting the opposite first and second end walls together;
• and
• a pair of attachment parts each extending axially of the core member from the respective opposite first and second end walls;
• wherein the vibration-damping bush is disposed so as to extend in a longitudinal direction of the vehicle body, and
• wherein said first end wall of the stopper member is provided adjacent to a first end surface of the vibration-damping bush in the longitudinal direction of the vehicle body so as to nearly fully cover the first end surface of the vibration-damping bush, and said first end wall of the stopper member has a through-hole formed therein for receiving one side of the core member, while said second end wall of the stopper member is provided adjacent to a second end surface of the vibration-damping bush in the longitudinal direction of the vehicle body, and is configured so as to cover only a part of the second end surface of the vibration-damping bush which is on a side of the connection part.
