Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reservoir with a level indicator.

For reservoirs with level indicators, if the switch case for level detection is engaged with the unevenness in the so-called snap-on type at the bottom of the reservoir, the reservoir may deform and leakage may occur.Also, when tightening the cap, do not insert a nut into the reservoir. It had drawbacks such as being time-consuming.

Therefore, the present invention was devised in view of the above points, and the rising portions at both ends of the switch case locking portion are
A switch case protruding from the reservoir bottom wall, the reservoir reinforcing bracket having a continuous outwardly bent fastening part formed at the tip of the rising part so as to hold the reservoir bottom wall and a part of the side wall connected thereto. The protruding end is locked to the switch case locking part, and a through bolt for tightening the cap is screwed into the fastening part.The purpose of this is to prevent liquid leakage from the switch case mounting part and to secure the cap. The purpose is to make installation easier.

An embodiment shown in the drawings will be described below.

Reference numeral 1 denotes a synthetic resin reservoir, and the vehicle body mounting portion 1a is connected to a bracket 2a of the vehicle body 2 with a bolt or the like (not shown).
Fix it by. Reference numeral 3 denotes a rotation preventing portion formed integrally with the synthetic resin reservoir 1, and is attached to the vehicle body 2 by a pin (not shown) inserted into a retaining pin hole 4. 5 is a synthetic resin reservoir 1 cap;
6 is a diaphragm held between the reservoir 1 and the cap 6, and 7 is a hose connection port for connection to the master cylinder.

8 is a switch case in which a reed switch, a resistor, etc. are fixed with adhesive, and the reservoir 1 is inserted into the switch case hole 9 formed in the reservoir bottom wall 1b.
Push in from the inside. 10 is an O-ring interposed between the reservoir bottom wall 1b and the switch case 8, 11 is a float having a magnet 12 on the inner circumference, and is loosely inserted into the switch case 8 established in the reservoir 1.
E-ring 13 prevents it from coming off. 1
Reference numeral 4 indicates an annular groove formed on the outer periphery of the protruding end of the switch case 8 which protrudes outward from the reservoir bottom wall 1b, and 15 indicates a lead wire.

16 is a reservoir reinforcement bracket made of metal etc.
Switch case locking part 1 with cutout 16a formed
6b, rising portions 16c and 16d at both ends thereof,
A fastening part 16e that is bent outward is continuously and integrally formed at the ends of both rising parts 16c and 16d, and a bolt hole 16f is formed in the fastening part 16e, and a nut 16g is welded to the fastening part 16e. 17 is a cap tightening through bolt.

Next, install reservoir 1 of this reservoir reinforcement bracket.
To install it, first insert the switch case 8 with the reed switch, resistor, etc. fixed with adhesive through the sketch case hole 9 in the reservoir bottom wall 1b, and then insert the O-ring 10 between the case 8 and the reservoir bottom wall 1b.
is established in reservoir 1 through
Loosely insert the float 11 into the switch case 8 inside,
The E-ring 13 is locked to the switch case 8 to prevent the float 11 from coming off.

Next, fit the reservoir reinforcing bracket 16 into the reservoir 1 from the direction of arrow A in FIG.
6a is fitted into the annular groove 14 of the switch case 8 to lock the switch case 8 to the locking portion 16b, and the locking portion 16b and both rising portions 16c and 16d are used to connect the reservoir bottom wall 1b and the reservoir side wall connected thereto. The portions 1c and 1d are provided so as to be held therein.

Then, put a specified amount of brake fluid into the reservoir 1, fit the cap 5 together with the diaphragm 6 into the reservoir 1, pass the cap tightening through bolt 17 from above the cap 5 through the side wall of the reservoir, and make it protrude from the bottom. It is inserted through the bolt hole 16f and screwed onto the nut 16g.

In the above embodiment, the nut 16g is welded to the fastening portion 16e of the reservoir reinforcing bracket 16.
A female thread may be formed directly on the fastening portion 16e. Further, in this embodiment, the master cylinder and the reservoir 1 are separated from each other for use in two-wheeled vehicles, but the invention is not necessarily limited to this, and they may be integrated.

In the present invention, as described above, the protruding end of the switch case is locked to the locking part of the reinforcing bracket made of a steel plate, etc., so that the switch case is securely engaged.
The deformation of the resin reservoir prevents liquid leakage, and even if the cap is removed when replenishing or replacing liquid, it will not disengage from the switch case, and the nut of the cap tightening bolt can be attached to the reservoir reinforcement bracket. Since it is integrated with the cap, it is easy to tighten the cap, making it an extremely excellent idea in practical terms.
