Housing for use with a variable resistor

A housing for use with a variable resistor consisting of a resistance element, a rotary shaft, a conductive slide plate and a top, said housing comprising:

• (a) a cylindrical body for supporting on its inner surface said resistance element, said cylindrical body having on its outer surface grooves elongated along its lengthwise direction;
• (b) a first cylindrical panel engaged with one open end of said cylindrical body to close the open end and rotatably supporting said rotary shaft;
• (c) a second cylindrical panel engaged with the other open end of said cylindrical body and rotatably supporting said rotary shaft;
• (d) at least one pair of resilient engaging projections extended from at least one of said first and second cylindrical panels along the axis of said cylindrical body, each of said pair of resilient engaging portions being formed as a plate-like shape and being guided by said grooves;
• and
• (e) engaging recesses formed on an outer periphery of said cylindrical body at predetermined positions and respectively engaging with said resilient engaging projections when said first and second cylindrical panels are engaged with said cylindrical body to make up said housing for the variable resistor.
