  "description": "歩道沿いや施設周辺の清掃シーンに置く小型道路清掃車。前方の二枚の円形ブラシと分離した毛束、支持腕、吸込ノズル・スカート・底部吸引管、密閉型前部キャブと左右の乗降段、独立した後部回収ホッパーを備えます。細い四輪、車軸、底部フレーム、後部ハッチとラッチ、鏡・ワイパー・非発光灯も造形。窓は不透明な青灰色の表現で、キャブ内装は省略。一式を1モデルと数えます。静止展示用で、走行・清掃・吸引・油圧動作、実機性能や安全性の検証はありません。 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）1.756 × 2.237 × 3.097 m、33,600三角形。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 compact street-sweeper prop for pavement edges and civic-facility maintenance scenes. Twin leading circular brushes have separated bristle bundles and support arms; the pickup nozzle, flexible skirts and underside suction conduit lead toward a separate rear waste hopper. A closed forward cab has side entry steps, opaque blue-grey glazing, mirrors and a wiper; its interior is omitted. Four narrow road wheels, axles, underside chassis, hopper hatch and latches, and inactive lamps complete one whole vehicle counted once. Static display only, without driving, sweeping, suction or hydraulic operation, real-machine performance or safety validation. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 1.756 × 2.237 × 3.097 m; 33,600 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.",
