The present invention provides a binding machine for gardening which can reduce a load at the time of a handle operation by reducing a load related to an operation of a lock member of a tape gripping apparatus. Specifically, the tape gripping apparatus (35) comprises: a support portion (36) which is provided along a drawing direction of a tape (60)； a gripping member (37) which is provided so as to face the support portion (36)； a gripping member biasing means (38) which biases the gripping member (37) toward the support portion (36)； a lock member (39) which is engaged with the gripping member (37) to hold the gripping member (37) in a standby position against biasing force of the gripping member biasing means (38)； and a lock member biasing means (40) which biases the lock member (39) in an engaging direction with the gripping member (37). The lock member (39) is rotatably attached to a clincher arm (30).[課題] 提供一種園藝用綑紮機，該園藝用綑紮機係藉由減少與膠帶握持裝置之鎖定構件的動作相關之負載，而可減少操作把手時之負載。[解決手段] 膠帶握持裝置35包括：支撐部36，係沿著膠帶60之拉出方向所設置；握持構件37，係被設置成與支撐部36相對向；握持構件偏壓手段38，係在支撐部36之方向對握持構件37賦與偏壓；鎖定構件39，係藉由與握持構件37卡合，在抵抗握持構件偏壓手段38的偏壓力下將握持構件37保持於待機位置；以及鎖定構件偏壓手段40，係在與握持構件37卡合之方向對鎖定構件39賦與偏壓。鎖定構件39係被安裝成對緊箝臂30可轉動。
