Abstract
To enhance the positioning accuracy between primary members and auxiliary members without need of latch parts such as rivets, an insertion frame structure includes: a pair of primary members having L-shaped cross-sections and placed with the L shapes facing to each other symmetrically; and several auxiliary members having angular U-shaped cross-sections between the primary members. The primary members and the auxiliary members are joined at latch portions. The latch portions of the primary members have clearance-shaped latch holes. The latch portions of the auxiliary members have convex portions to be inserted into the latch holes. Each latch hole has a clearance with a larger dimension than a plate thickness t of the auxiliary members, and continuously from the clearance, a clearance with a dimension smaller than the plate thickness t of the auxiliary members.
