PROBLEM TO BE SOLVED: To prevent the damage and breakage of a function by forming an abutting part deformable in the direction in which stress due to tightening of a tightening member is released in a member product in a device constituted by assembling member products such as a valve mechanism, strainer, etc., into a main body product of various equipment such as a valve device. SOLUTION: When this device is applied to an automatic combination faucet constituted by assembling a cartridge 2 in which a mixing valve mechanism and a thermoelement are built-in, a contact face (a) is formed on the upper face side of a shoulder part of a casing 20 of the cartridge 2, the contact face (a) is brought into contact with a body 1 in which the cartridge 2 is fitted and mounted, and a stopper part keeping the cartridge 2 at a predetermined position in the body 1 is protrusively provided. An abutting part (c) abutting on a support face (b) on the upper face side of a tightening member 3 is formed on the lower face side of the casing 20, and an escape groove (d) is formed above the abutting part (c). Consequently, when the tightening member 3 is screw-fitted in a mounting port of the body 1 and is tightened, tightening stress can be absorved due to the deformation of the abutting part (c).
