置とを有することを特徴とする筋力測定装置。(1) While the subject is sitting on a chair, the tip of the lower leg is attached to a pedal attached to a movable rod extending forward from the chair in the area from the position where the lower limb is bent to the position where the lower limb is extended. This is a muscle strength measurement device that applies force to measure the muscle strength of the subject, and includes a horizontal force sensor that is attached to the pedal and detects the force applied from the lower limb in the longitudinal direction of the rod; a vertical force sensor that is attached to a pedal and detects a force applied from the lower limb in a direction perpendicular to the longitudinal direction; and a rod drive device that moves and stops the rod in the axial direction under preset movement conditions. A muscle strength measuring device comprising:
ていることを特徴とする請求項（１）に記載の筋力測定
装置。(2) The muscle strength measuring device according to claim (1), wherein the chair is configured to be movable in a direction perpendicular to the rod.
