FIXING MEMBER, PROXIMITY SENSOR, PROXIMITY SENSOR ATTACHING STRUCTURE, AND ROTATIONAL CONNECTION STRUCTURE AND ROTATIONAL CONNECTION STRUCTURE PRODUCING METHOD

Document Type and Number:

WIPO Patent Application WO/2011/039892

Kind Code:

A1

Abstract:

A fixing member (12) is comprised of a first fixed portion (21); an opening (24) which is spaced from and opposed to the first fixed portion (21); and a fastening portion (40) which is disposed and fixed in a space (23) between the first fixed portion (21) and a second fixed portion (22) which cannot be moved relative to the first fixed portion (21). The fastening portion (40) is shaped so as to rotate about the rotation axis (L) of the first fixed portion (21) extending in a direction in which the rotation axis penetrates the opening (24). Further, the fastening portion (40) is comprised of a first abutment portion (51) abutting with the first fixed portion (21), and a plurality of second abutment portions (52) abutting with a plurality of portions of the periphery of the opening (24). Each second abutment portion (52) has a guide inclined surface (42). The guide inclined surfaces (42) are arranged around the rotation axis (L). Each guide inclined surface (42) is inclined in the circumferential direction of the fastening portion (40) so that one end of the guide inclined surface in the rotational direction of the fastening portion is closer to the opening (24) than the other end thereof. Each guide inclined surface (42) is also inclined in the radial direction of the fastening portion (40) so that the portion of the guide inclined surface (42), which is closer to the rotation axis (L), is closer to the opening (24). The fastening portion (40) is secured by rotating the fastening portion (40) so that the guide inclined surfaces (42) are pressed against the second fixed portion (22).
