As to independent claim 1, Mori teaches a solenoid comprising: a first member (43) including a peripheral portion to cover a periphery of a coil (37) contained in a cylindrical housing (25), the first member (43) covering an opening of the housing (25); a second member(44) provided around an outer periphery of the first member (43), the second member (44) being configured to be disassemblable; and a sealing element (see figure 2) disposed inside the second member (44), the sealing element (see figure 2) being configured to prevent foreign matters from entering the housing (25), wherein the first member (43) and the second member (44) include restraining portions (inherent in a nut to restrict movement) configured to engage each other to restrain the second member (44) from rotating about a centerline of the housing (25) relative to the housing (25) as shown in figure 2. As to claims 2/1, 6/5 and 10/9, Mori teaches wherein the second member (44) is configured to be assemblable onto the housing (25) in a state where the second member (44) is coupled to the first member (43) as shown in figure 3. As to claims 4/1 and 8/5, Mori teaches wherein the sealing element (see figure 2) is configured to be assemblable onto the housing (25) in a state where the sealing element is coupled to the second member (44) as shown in figure 2. As to independent claim 5, Mori teaches a solenoid comprising: a first member (43) including a peripheral portion to cover a periphery of a coil (37) contained in a cylindrical housing (25), the first member (43) covering an opening of the housing (25); a second member (44) provided around an outer periphery of the first member (43), the second member (44) being configured to be disassemblable; and a single sealing element (see figure 2) configured to prevent foreign matters from entering the housing (25) through between the first member (43) and the second member (44) and between the housing (25) and the second member (44) as shown in figure 2. As to independent claim 9, Mori teaches a solenoid comprising: a first member (43) including a peripheral portion to cover a periphery of a coil (7) contained in a cylindrical housing (25), the first member (43) covering an opening of the housing (25), the first member (43) being provided with a recess depressed from a surface of the first member (43) that faces the opening; a second member (44) of a cylindrical shape provided around an outer periphery of the first member (43), the second member (44) having one end thereof contacting the recess, the second member (44) being configured to be disassemblable from the first member (43); a first sealing element (see figre 2) disposed on a contact surface between the first member (43) and the second member (44), the first sealing element (see figure 2) being configured to prevent foreign matters from entering the housing (25) through between the first member (43) and the second member (44); and a second sealing element (see figure 2) with a different radial size than the first sealing element, the second sealing element (see figure 2) being configured to prevent foreign matters from entering the housing (25) through between the housing (25) and the second member (44) as shown in figure 2. As to claim 12/9, Mori teaches wherein the second sealing element (see figure 2) is configured to be assemblable onto the housing (25) in a state where the second sealing element (see figure 2) is coupled to the second member (44) as shown in figure 2. As to independent claim 13, Mori teaches a method of assembling a solenoid, the solenoid comprising: a first member (43) including a peripheral portion to cover a periphery of a coil (7) contained in a cylindrical housing (25), the housing (25) including, in a portion of a circumference thereof, a cutaway portion depressed from an outer circumferential surface thereof, the first member (43) covering an opening of the housing (25); a second member (44) including a protruding portion configured to engage the cutaway portion, the second member (44) being provided around an outer periphery of the first member (43), the second member (44) being configured to be disassemblable; and a sealing element (see figure 2) disposed inside the second member (44), the sealing element (see figure 2) being configured to prevent foreign matters from entering the housing (25), the method comprising: inserting the peripheral portion into the housing (25) in a state where the protruding portion is fitted in the cutaway portion to restrain the second member (44) from rotating relative to the housing (25) and the second member (44) is coupled to an outer periphery of the first member (43) with the sealing element (see figure 2) disposed inside the second member (44) as shown in figure 2. Allowable Subject Matter Claims 3,7,and 11 objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
