Assuming that the direction of movement is the left-right direction, it is preferable that the engaging part has a positioning part that defines the position of the top cover in the left-right direction with respect to the back cover. According to this configuration, when combining the top cover and the back cover, it is possible to easily position the top cover with respect to the back cover in the left-right direction.

In the faucet, the engaged part has a protruding wall extending in the thickness direction of the back cover, and the engaging part has a vertical wall extending downwardly of the top cover and a lower end of the vertical wall. It is preferable that the regulating portion has a horizontal wall extending laterally from the horizontal wall, and that the restricting portion is constituted by the horizontal wall. According to this configuration, upward deformation of the top cover can be suppressed by engaging the horizontal wall of the top cover with the lower surface of the protruding wall of the back cover. Therefore, it is possible to suppress the disengagement of the top cover and the back cover above the faucet main body.

Regarding the faucet, if the direction in which the faucet main body and the back cover overlap is defined as the front-rear direction, it is preferable that the vertical wall extends along the front-rear direction. According to this configuration, when the vertical wall of the top cover is engaged with the protruding wall of the back cover, the top cover can be guided in a stable state along the protruding wall. Therefore, the ease of assembling the top cover can be improved.

In the above faucet, it is preferable that the engaging part has a positioning part that defines a position of the top cover in the left-right direction with respect to the back cover, and the positioning part is formed of the vertical wall. . According to this configuration, since the top cover can be positioned in the left-right direction using the vertical wall, there is no need to separately provide a positioning section. Therefore, the configuration of the engaging portion can be simplified.
