A magnet holder (10) for use in an analogous or digital throttle position sensor for sensing the angle of a butterfly valve in a fuel supply unit of an internal combustion engine, said magnet holder (10) including a throttle lever member (11) adapted to be fixed to a shaft of the butterfly valve and carrying at least one magnet (17). A recess (12) for the magnet (17), or for each magnets if more than one magnet is used, is provided in the throttle lever member (11), the magnet (17) is located in said recess (12), or the magnets are located in said recesses if more than one magnet is used, and throttle lever member material (18) located around an entrance to the recess (12) or entrances to the recesses is staked over the magnet (17) or magnets, respectively, to cover each magnet (17) sufficiently to retain it in its associated recess (12). Thereby, the magnet/magnets (17) will be securely retained in the magnet holder (10) and the manufacturing of the holder can be done in production, particularly in large numbers such as mass production.
