Abstract

A spring mounting structure includes a first structural member and a second structural member. The first structural member includes: a first abutting surface to abut on one end of a compression spring; and a temporary holding portion to temporarily hold the compression spring in an uncompressed state. The second structural member includes: a second abutting surface to abut on another end of the compression spring; and a tapered surface to, when the second structural member is assembled in a predetermined assembling direction intersecting a compression direction of the compression spring, guide the other end of the compression spring in the uncompressed state temporarily held by the temporary holding portion to the second abutting surface such that the compression spring is mounted in a compressed state between the first and second abutting surfaces.
