[0004]

The conventional retractable parking brake operating device as described above has a structure in which the operating lever is folded and stored in the middle (pin attachment portions of the first lever and the second lever). Therefore, not only is it impossible to take a sufficiently low storage position, but also a portion behind the pin attachment portion of the second lever base end portion (the rear portion has a moderation between the use position and the storage position with moderation). Since the engaging mechanism for holding is provided, the first lever is extended rearward to near the portion where the first lever is attached to the bracket.) When the second lever is pivoted downward, it pivots upward. In order to escape the upward rotation of the rear part of the lever, a projection projecting upward must be provided at the rear part of the upper surface of the first lever, and the downward rotation angle of the second lever is increased to increase the storage position. The more you try to lower it, the more its convex Upwardly projecting amount inevitably increases, there is a problem that is sometimes forced to change peripheral parts of the body side by the convex portions.

[0005] The present invention has as its main object to solve the above conventional problems.
