Suspension apparatus

A suspension apparatus comprising:

• a leaf spring in which a front end and a rear end are rotatably supported by a frame of a car and an intermediate portion in a longitudinal direction is attached to an attaching member for a wheel, wherein only one leaf spring is equipped in the apparatus, and is supported by the frame such that a portion to a rear of a breaking point of the leaf spring can rotate and contact the ground in a case of the breakage of the leaf spring at a portion to a rear of the intermediate portion;
• and
• a blocking means for blocking rotation of the portion to the rear of the breaking point of the leaf spring only when the leaf spring is broken at the portion to the rear of the intermediate portion,
• wherein the blocking means is a stay in which the portion to the rear of the breaking point of the leaf spring rotates and comes into contact with the stay in a case of the breakage of the leaf spring at the portion to the rear of the intermediate portion, and
• wherein the stay is supported by the frame so as not to rotate
• wherein the stay is spaced a predetermined distance from the leaf spring before breakage of the leaf spring, wherein the predetermined distance is greater than a maximum deflection of the leaf spring so that the leaf spring and the stay do not come into contact with each other unless the leaf spring is broken at the portion to the rear of the intermediate portion.
