Abstract

PURPOSE:To make machining of an oil level angle side unnecessary by providing a cut at the oil level angle side contiguous to or in vicinity to a contiguous point of a seal angle side and the oil level angle side of a seal lip. CONSTITUTION:A so called cut (E) is made at an oil level angle side (B) of a seal lip 3, contiquous to or in vicinity to a contiquous point (C). Rubber lining at thic cut (E) forms an acute angle, while thin film is generated at a section contiguous to the oil level angle side (B). These rubber linings can be cut by a press or like instruments or manually torn off and the cut (E) and the oil level angle side (B) are easily separated.
