Oral sleep appliance

A coupling member includes a sliding member and a sleeve. The sliding member has one axial direction end portion coupled to a first attachment portion provided at a first attachment that is mounted to one of a maxilla or a mandible. The sleeve has one axial direction end portion coupled to a second attachment portion provided at a second attachment that is mounted to the other of the maxilla and the mandible. The sliding member is inserted into the sleeve so as to be slidable. A restricting section is formed at the sleeve between two axial direction end portions of the sleeve so as to restrict sliding of the sliding member in both directions along an axial direction of the sliding member.

A dental coupling member related to a first aspect of the invention comprises: a rod having, at one end region, a first coupling part that is coupled to a first attachment part of a first dental tool, and having a screw part at the other end region; and a cylindrical body having, in an inner circumferential surface of one end region, a screwed part into which the screw part is screwed, and having, at the other end region, a second coupling part that is coupled to a second attachment part of a second dental tool. This dental coupling member comprises a different-torque part at the screw part and/or the screwed part, the different-torque part having a different torque for screwing against the other of the screw part and the screwed part. This dental coupling member suppresses the occurrence of loosening between the screw part and the screwed part.

The purpose of the present invention is to provide a method for efficiently producing an olefin (co)polymer containing a constituent unit derived from 1-butene, the (co)polymer having a molecular weight that is sufficiently high even for high temperature conditions that are beneficial for industrial production methods. This purpose can be achieved by means of a method for producing an olefin (co)polymer containing a constituent unit derived from 1-butene, wherein at least 1-butene and, if necessary, an &#x3b1;-olefin having 2 or more carbon atoms (excluding 1-butene) and other monomers are (co)polymerized in the presence of an olefin polymerization catalyst that contains (A) a crosslinked metallocene compound represented by general formula [I] and (B) at least one type of compound selected from among (b-1) an organic aluminum oxy compound, (b-2) a compound that forms an ion pair upon a reaction with the crosslinked metallocene compound (A), and (b-3) an organic aluminum compound, at a polymerization temperature of 55-200&#xb0; C. and a polymerization pressure of 0.1-5.0 MPaG.
