A seat capable of changing an inclination angle of a front end of a seat cushion, the seat comprising:

• a side frame forming a part of a framework of the seat cushion, the side frame being arranged on one end side of the seat in seat-width directions and extending in front-rear directions of the seat;
• a tilt arm configured to change an inclination angle of a front end of the seat, the tilt arm extending in the front-rear directions of the seat, a rear end of the tilt arm being pivotably coupled to the side frame;
• a pivot arm configured to pivotably displace the tilt arm, a front end of the pivot arm being pivotably coupled to a front end of the tilt arm, a rear end of the pivot arm being pivotably coupled to the side frame;
• and
• a tilt pin rotatably coupling the pivot arm to the side frame, the tilt pin being arranged anterior to a connecting portion connecting the side frame and the tilt arm, and extending in the seat-width directions,
• wherein a concave or U-shaped through hole is formed in a front end of the side frame, the through hole having the tilt pin inserted therethrough and being recessed rearward from an opening at the front end of the side frame, and
• wherein a falling-out inhibiting member is fixed to the side frame, the falling-out inhibiting member being configured to inhibit the tilt pin from falling out of the opening at the front end of the side frame.
