1. An optical receptacle, comprising:
an optical component assembly including:
a light-guiding member;
a cylindrical member which retains the light-guiding member in a through hole thereof; and
a projection which is provided at one end of the cylindrical member so as to extend beyond an outer periphery of the cylindrical member, and is engageable in a groove which is formed in a cylindrical shell so as to extend in an axial direction of the cylindrical shell and then turn in a circumferential direction of the cylindrical shell;
a sleeve disposed at a front end part of the light-guiding member; and
a cylindrical shell which covers an outer periphery of the sleeve, and has a groove which is formed at a rear end part of the cylindrical shell so as to extend in the axial direction of the cylindrical shell and then turn in the circumferential direction of the cylindrical shell, wherein
a protrusion is disposed on one end face of the cylindrical member,
the protrusion protrudes in an axial direction of the cylindrical member from the one end face,
the projection is placed at a side face of the protrusion,
the cylindrical shell is fixable by engagement of the groove with the projection, and
a rear end face of the sleeve abuts on a front end face of the protrusion, and a gap is present between the rear end face of the sleeve and one end face of the cylindrical member.
