PROBLEM TO BE SOLVED: To provide a parking brake mechanism capable of eliminating the need of the installation of a snapring for slip-off prevention of operating force transmission pins inserted into pin insertion holes in a parking lever. SOLUTION: A gap 67 into which one ends of link plates 61, 63 can be inserted is formed at one end of the parking lever 53 by bending a plate member in a generally U-shape. The pin insertion holes 71, 72 are formed through a pair of opposed plate parts 53a, 53b forming the gap 67. The operating force transmission pins 56, 57 have both end outer diameters corresponding to the pin insertion holes 71. 72. The intermediate parts of the pins are formed in a stepped structure smaller in diameter the pin insertion holes 71, 72. Since one ends of the link plates 61, 63 inserted into the gap 67 are engaged with the intermediate parts of the operating force transmission pins 56, 57, the operating force transmission pins 56, 57 are locked from the parking lever 53.
