Attachment of the gauge body 40 to the rail portions 48 is performed with respect to three rail portions 48 arranged at positions where the sender gauges 18 are arranged on the outer peripheral surface 39 of the unit case 38 . Therefore, in this embodiment, since the rail portion 48 is formed all over the circumference of the outer peripheral surface 39 of the unit case 38, the sender gauge 18 can be set at any position on the circumference. Hereinafter, description will be made in order with reference to FIGS. 8 to 11. FIG.

FIG. 8 shows the initial state (mounting process 1) of mounting the gauge body 40 of the sender gauge 18 to the outer peripheral surface 39 of the unit case 38 . In this state, only the first guide portion 54A of the first mounting portion 52A of the gauge body 40 is fitted to the rail portion 48. As shown in FIG. This state is indicated by a circle frame S1 in FIG. That is, in this state, since the lower guide portion 54Aa of the first guide portion 54A is at the lowest position, only this lower guide portion 54Aa is fitted with the rail portion 48. As shown in FIG.

The first guide portion 54A of the first mounting portion 52A, which is slide-fitted with the rail portion 48 first, is located at the center position between the second mounting portion 52B and the third mounting portion 52C on both sides. As a result, rattling when the gauge body 40 is attached to the unit case 38 can be suppressed. Then, by sliding down the gauge body 40 along the first guide portion 54A of the first mounting portion 52A, the second mounting portion 52B and the third mounting portion 52C that are to be fitted to the rail portion 48 after that. The alignment time can be shortened, and the ease of assembly can be improved. That is, by assembling in order of the guide portion 54 of the first mounting portion 52A, the snap-fit structure 56 of the second mounting portion 52B, and the press-fitting of the second mounting portion 52B and the third mounting portion 52C, the ease of assembly is improved. can be improved.

FIG. 9 shows a state in which the gauge body 40 is slightly lowered from the state shown in FIG. 8 (mounting process 2). This state illustrates the snap-fit formation 56 of the second mounting portion 52B beginning to engage the rail portion 48. As shown in FIG. This state is indicated by a circle frame S2 in FIG. In this state, the upper end of the rail portion 48 engages the locking portion 60 of the snap-fit structure 56, causing the post 58 to flex and deform. In this state, since rattling of the gauge body 40 is suppressed in the state shown in FIG. done. Therefore, in the subsequent downward sliding movement, the flexural deformation of the struts 58 is reliably performed, and the snap-fit action can be performed reliably.

FIG. 10 shows a state in which the gauge body 40 is further lowered from the state shown in FIG. 9 (mounting process 3). In this state, the upper end of the rail portion 48 faces the second guide portion 54B of the second mounting portion 52B and the third guide portion 54C of the third mounting portion 52C. This state is shown in FIG. 10 by circular frames S3 (second mounting portion 52B) and S4 (third mounting portion 52C). By moving further downward from this position, the rail portion 48 is press-fitted into the second guide portion 54B and the third guide portion 54C. As a result, the gauge body 40 is securely attached to the unit case 38 via the rail portions 48 .

FIG. 11 shows the state in which the gauge body 40 has been slid downward in one direction (mounting step 4). In this state, the rail portion 48 is completely press-fitted into the second guide portion 54B of the second mounting portion 52B and the third guide portion 54C of the third mounting portion 52C, and the sender gauge 18 is connected to the pump unit. 24 is securely positioned and attached. In this state, the locking portion 60 of the snap-fit structure 56 is positioned away from the lower end of the rail portion 48, and the post 58 is returned from the bent state to the free state. As a result, when the gauge body 40 attempts to move upward, the upper surface of the engaging portion 60 and the lower end surface of the rail portion 48 come into contact with each other to prevent the gauge body 40 from being pulled out. That is, it is possible to prevent the gauge body 40 from coming off the unit case 38 . When the gauge body 40 needs to be forcibly removed, it can be removed by manually releasing the contact state.

In addition, according to the assembly sequence described above, the assembly can be easily performed only by applying a downward force to the gauge body 40 in one direction. Moreover, since the first guide portion 54A of the first mounting portion 52A is guided and mounted earlier than the others, it is possible to assemble while suppressing rattling.
