A blow mold for blow-molding a resin container equipped with a grip portion, comprising:
- a cavity mold composed of a pair of split molds for forming a cavity in which a bottomed cylindrical preform is to be housed;
- a link member having one end side pivotably supported by a shaft member, and having on another end side a recess insert die which presses the preform during blow molding to form the grip portion;
- and
- a cam member which is provided lateral to the cavity mold so as to be linearly movable, and which presses the link member in accordance with a linear movement thereof to pivot the link member, wherein
- the cam member has a first cam portion for pressing the link member toward the cavity in accordance with the linear movement to pivot the link member, and
- the cam member has a second cam portion for pressing the link member toward an outside of the cavity to pivot the link member.
