1. An automatic brake device for an industrial vehicle comprising:
a brake pedal that is pivotably supported by a bracket;
a brake master cylinder in which brake pressure is generated by the brake pedal stepped on; and
an actuator that is operated during automatically braking, and configured to generate brake pressure in the brake master cylinder, wherein
the automatic brake device includes:
a first pivotable link member that is coupled to the brake master cylinder; and
a second pivotable link member that is coupled to the actuator,
the brake pedal includes a pedal-side contact portion that is configured to pivot the first pivotable link member,

the first pivotable link member includes:
a first contacted portion that is contactable with the pedal-side contact portion; and
a second contacted portion that is contactable with the second link-side contact portion,
the first pivotable link member is pivoted by the pedal-side contact portion pressing the first contacted portion while the brake pedal is stepped on, simultaneously the second contacted portion being moved away from the second link-side contact portion, and
the first pivotable link member is pivoted by the second link-side contact portion pressing the second contacted portion while the actuator is operated, simultaneously the first contacted portion being moved away from the pedal-side contact portion, and
wherein
the automatic brake device includes a pivot shaft that pivotably supports the brake pedal, the first pivotable link member, and the second pivotable link member,
