摘要： The die 18 of the self-piercing rivet fastening device is equipped with a center pin 25 for receiving the hollow section of the legs 5 on the self-piercing rivet 1 and a die main body 27 having a cavity 26 for guiding the distortion of the tip of the legs on the self-piercing rivet outward radially on the outer periphery of the center pin 25. The center pin 25 and the die main body 27 are supported so as to move relatively freely in the axial direction of the center pin 25 towards the punch 14. It also has a plate spring 41 allowing the center pin 25 to move relative to the die main body 27 so the center pin 25 comes into contact with the die end surface of the fastened member 3 on the receiving end when the self-piercing rivet 1 under pressure from the punch 14 is driven into the fastened members 2, 3 and the tip of the legs begins to pierce the fastened member 3 on the receiving end. This reduces or eliminates the constraints on the fastened members in the rivet-driving direction.
摘要翻译：自穿铆钉紧固装置的模具18配备有用于接收自穿孔铆钉1上的腿部5的中空部分的中心销25和具有空腔26的模具主体27，模具主体27用于引导穿刺铆钉在中心销25的外周径向外侧的自刺铆钉的顶端。中心销25和模具主体27被支撑成沿着中心销25的轴向方向相对自由地向着冲头14.还具有允许中心销25相对于模具主体27移动的板簧41，使得当自身的中心销25在接收端与接合件3的模具端面接触时来自冲头14的加压铆钉1被驱动到紧固构件2,3中，并且腿的尖端开始刺穿接收端上的紧固构件3。这减少或消除了铆钉驱动方向上的紧固构件的限制。

摘要： A suspension support member is mounted on a vehicle body to support a coil spring and a shock absorber forming a suspension, and is formed of a cast article including a spring seat for the coil spring and a pivot support section for the shock absorber, which are disposed independently from each other. Thus, the suspension support member is provided which ensures that the supported positions of the coil spring and the shock absorber in the suspension can be determined simply with a good accuracy, and which has a high rigidity and moreover, enables the generation of noises to be inhibited remarkably.

摘要： In a space frame type vehicle body structure, a floor member has a side sill inner half securely attached along each side edge thereof, and a side frame has a side sill outer half securely attached along a lower edge thereof, and these two halves are provided with mutually cooperating snap fit arrangement. Because the floor member and the side frame are individually provided with a sufficient rigidity, and they can be temporarily secured each other simply by pushing them against each other, they can be welded together with a high dimensional precision without requiring any massive or complex clamping fixture.
