Title: FINE HOLLOW PROTRUSION IMPLEMENT
Abstract:
In a fine hollow protrusion implement (1) according to the present invention, a fine hollow protruding portion (3) which has an opening portion (3h) on a distal end side thereof and inside which is formed an internal space joined to the opening portion (3h) protrudes from a base member (2). When any longitudinal section passing through the apex of the fine hollow protruding portion (3) is viewed, the wall thickness (T1) of an apex-side part (TB) on the apex side is less than the wall thickness (T2) of a lower-side part (BP) further toward the base member (2) than the apex-side part (TB), and a gap (M1c) between inner walls (31, 31) in the apex-side part (TB) is smaller than a gap (M2c) between the inner walls (31, 31) in the lower-side part (BP). A root portion (34) of the fine hollow protruding portion (3) protruding from the base member (2) has a curvature, and an inlet portion (23) where a rear surface (25) of the base member (2) enters the fine hollow protruding portion (3), on the opposite side to a top surface (24) of the base member (2) which protrudes out to the fine hollow protruding portion (3), has a curvature.
