In a door handle assembly: the number of parts of a handle holding mechanism for holding a handle (10) in its retracted, its projected and its swung position is reduced to the lowest possible one to accomplish its cost reduction, its downsizing and its improvement in handle holding power; a leaf spring (11) constructed of a pair of its elements stacked together is non-rotatably mounted on a boss (7) of a main pin (3) having a concave portion (13) in its front surface; the handle (10) with an engaging projection (14) is brought into abutting contact with the leaf spring (11); in its folded position, the handle (10) has its top portion (14a) oppositely disposed from its grip portion (15) with respect to a reference line (39) extending perpendicular to a door surface; in its projected position, the handle (10) has the top portion (14a) move across the line (39); a front element of the spring (11) has a pair of upwardly protruding portions (33, 34) be engageable with and disengageable from engaging grooves (31, 32) of a first (14a) and a second (14c) oblique surfaces of the engaging projection (14).
