Document Type and Number:
Japanese Patent JPS6263253
Kind Code:
A
Abstract:
PURPOSE:To improve sealability, by providing seal members at suitable portions in a casing into which a foreign matter such as dust tends to penetrate. CONSTITUTION:A seal member 101 is interposed between a spacer 90 and a pusher member 40 to seal a gap defined between the inner surface of the spacer 90 and the outer surface of the pusher member 40. A seal member 102 is engaged externally with an insert portion 42a of a cap 42, and is interposed between the insert portion 42a and the pusher member 40 when the cap 42 is inserted into the pusher member 40. Accordingly, all gap portions in a casing 20 are sealed by the seal members, thereby preventing dust, water, oil or the like in an equipment from penetrating into the casing. Thus, sealability may be improved.
