<p>PURPOSE:To automate the insertion of an insertion member in regard to a valve body whose hole diameter becomes smaller in plural steps. CONSTITUTION:In the case of work unit assembly method by which a work unit is assembled by inserting an insertion member 3 into the insertion hole 2 of a work body 1, the work body 1 is made to be the one that has a large diameter insertion hole 2a formed axially and a small diameter insertion hole 2b formed concentrically with this large diameter insertion hole 2a, and an approximately cylindrical guide means 6 whose outer diameter coincides approximately with the diameter of the large diameter insertion hole 2a of the work body 1 and whose inner diameter coincides approximately with the diameter of the small diameter insertion hole 2b, is temporarily inserted into the large diameter insertion hole 2a, and the insertion member 3 is inserted into the small diameter insertion hole 2b by the guide of the guide means 6.</p> |
