Abstract
A locking structure of a cap-member to a cylindrical body, being capable of giving sufficient resilience to a locking arm formed on the cap-member, is provided, which consists of: a resilient locking arm provided on a peripheral wall of the cap-member in a peripheral direction thereof; and an engaging groove provided on the cylindrical body for engaging the locking arm simultaneously with fitting of the cap-member on the cylindrical body. The locking arm is provided with an engaging projection projecting from a free end portion thereof toward a longitudinal axis of the cap-member and having a tapered surface inclined in a fitting direction of the cap-member and an engaging plane on a back of the tapered surface to engage the engaging groove. A plurality of the locking arms are arranged on the peripheral wall of the cap-member. The locking structure may further include an annular sealing member to be retained between the cap-member and a holder body formed continuously from the cylindrical body. The cap-member is axially fixed to the cylindrical body by means of the engaging plane of the locking arm and an annular plane inside the cap-member. Thus, a locking structure capable of eas…
