Abstract: A torsion spring installation means for a vehicle sunroof, front frame and vehicle sunroof. The torsion spring may have spring coils, a first torsion arm and a second torsion arm. The torsion spring installation means has a recess, the recess being configured as a cavity having an opening, for the purpose of receiving the spring coils, and having a wall and a recess bottom; a receiving component, the receiving component having an opening part, in order to receive the first torsion arm; wherein a guide block is provided on a first wall face of the wall in a fixed manner, the guide block extending out from the first wall face in such a way that its size gradually diminishes. The present means provides convenience of installation and removal, ease of maintenance and replacement, effective prevention of water penetration, the ability to prevent jumping out and wobbling, an extended service life.
