PROBLEM TO BE SOLVED: To provide a technology capable of easily assembling a thermoactuator.SOLUTION: A sleeve 80 for supporting a piston 60 so as to be capable of advancing and retreating is installed in a case 20 of a thermoactuator 10, and a sleeve groove part 82 recessed toward the central axis PC of a rod 70 is formed on the outer periphery of the sleeve 80. When the rod 70 exists in a rear end position, a rod groove 75 recessed toward the central axis PC of the rod 70 is formed in a part exposed from the case 20 of the rod 70. A boot 90 is formed with a sleeve fitting part 91 fitted to the sleeve groove 82 and a rod fitting part 92 fitted to the rod groove part 75. The sleeve fitting part 91 is fitted to the sleeve groove part 82 and the outer periphery of the sleeve fitting part is pressed by the case 20. The rod fitting part 92 is fitted to the rod groove 75 and the outer periphery of the rod fitting part is pressed by a cap member 18 installed on the rod 70. |
