Lock construction
A lock construction that minimizes the friction coefficient between the slide pin and the slide pin hole through the design of an arc-shaped indentation formed on each interior wall of the slide pin holes, which receives the rectangular slide pin. The lock construction includes an outer fixed body and an inner rolling body, a hooking recess formed in an inner peripheral surface portion, a receiving recess formed in an outer peripheral surface portion of the inner rolling body, wherein a slide bar having a linearly formed inner side is elastically provided in the locking construction, wherein about five slide pin holes of rectangular shape are formed perpendicular to the receiving recess, wherein an arc-shaped indentation is formed on each interior wall of the slide pin holes. A plurality of rectangular slide pins with grooves differing in height and protrusions differently opposing the grooves so that the grooves may serve as the receiving recess and the protrusions may open to and be received by the openings.
