<p>PURPOSE: To provide a simple, low-cost, easily assembled/disassembled pivotable joint where a first part has pivot bores and a second part has resilient pivot pins. CONSTITUTION: The first part 1 with pivot bores 3 has a closed tubular cross section, and the second part 2, a throttle valve, has resilient pivot pins 5. The pivot pins 5 change the original three-dimensional position during assembling, and snap resiliently into the pivot bores 3 of the first part 1 when the second part reaches the desired assembled position.</p> |
