A seatbelt apparatus that is capable of improving seatbelt wearing operability may comprise a webbing, a tongue plate moveably attached to the webbing, which are provided with a grip portion to be gripped by an occupant and an engagement portion extending from the grip portion, and a buckle that receives and releases the engagement portion of the tongue plate for engagement and disengagement. A leather cover is applied to a front surface (corresponding to the palm of the occupant's hand for gripping) of the grip portion of the tongue plate.
