  "description": "自動車整備ガレージの床に置く、低い車輪付きフロアジャッキ。開いた左右シャーシ、固定前輪と後部旋回キャスター、持ち上げアームと水平リンク、丸いゴム付きサドル、油圧シリンダー、ポンプ機構と斜めの長いハンドルを個別造形しています。車両、ジャッキスタンド、荷物は含みません。外観用の静的プロップであり、揚重能力・安全性・実動作を示さず、設計・操作・安全指示や認証ではありません。 ゲーム・可視化向け。製造・構造設計・3Dプリント用途は未検証。 外接寸法（X×Y×Z）0.458 × 1.038 × 1.414 m、15,104三角形。単位m・Y-up、水平中央の接地用原点、最下点Y=0。部品ごとの重複UV0と単色PBR材質を収録し、画像テクスチャ・UV2・コライダー・LOD・リグ・動作は付属しません。静的表示用でUnity/VRChat実機検証は未実施。STLはm・Y-up座標の形状のみで色・材質・UV・階層を含みません。",
  "descriptionEn": "A low wheeled floor jack for automotive service-garage scenes, with an open paired chassis, fixed front rollers, rear swivel casters, raised lifting arm and leveling links, rubber-inset round saddle, hydraulic barrel, pump details and a long inclined handle. Vehicle, axle stands and load are not included. This is a static appearance prop, not load-rated, safe or functioning equipment; it provides no engineering, operation or safety instructions and no certification. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.458 × 1.038 × 1.414 m; 15,104 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or wall-mount pivot. Includes overlapping component UV0 and constant-color PBR materials, with no image textures, unique UV2, colliders, LOD, rig or runtime behavior. Static visualization only; Unity/VRChat editor and runtime tests have not been performed. STL uses metre-valued Y-up coordinates and contains geometry only, without color, materials, UVs or hierarchy.",
