The hot water mixing faucet A can adjust the amount of water discharged by rotating the flow rate adjusting handle 61, and the amount of water discharged can be set to zero, that is, water can be stopped.

Further, the hot water mixing faucet A can adjust the water discharge temperature to a desired temperature by rotating the temperature adjusting handle 60. At this time, in order to set the temperature above a certain level, it is necessary to rotate the temperature adjusting handle 60 while pressing the safety button 52 provided on the temperature adjusting handle 60.

FIG. 12 is an exploded perspective view showing the inside of the temperature adjusting handle 60 corresponding to FIG. 2 of Patent Document 1. FIG. 13 is a cross-sectional view of the temperature adjusting handle 60. The temperature control handle 60 has a safety button 52, a bush 54, and a leaf spring 55 in a form of being attached to a cover portion 65 that covers the periphery thereof.

In the conventional hot and cold water mixing faucet A, when the user grasps and rotates the cover portion 65 of the temperature adjusting handle 60, the base portion (not shown) fitted with the cover portion 65 is rotated, and the hot and cold water mixing faucet A is rotated. The mixing amount of hot water of A is adjusted. Thereby, the temperature of the water discharged from the spout 62 can be freely adjusted from water to hot water (or vice versa).

Here, a safety device is provided for the rotation of the cover portion 65 so that hot water having a temperature higher than a certain temperature is not accidentally discharged. Specifically, as shown in FIGS. 12 and 14 (corresponding to FIG. 5 of Patent Document 1), a locking portion 53 connected to the safety button 52 is provided, and is provided in the hot water mixing faucet A. The cover portion 65 cannot rotate by coming into contact with the rotation restricting stopper 56.

When it is desired to discharge hot water having a temperature higher than a certain temperature, the safety button 52 connected to the locking portion 53 is intentionally pressed. As a result, the locking portion 53 is moved toward the inside of the temperature adjusting handle 60. As a result, the contact (cooperation) between the locking portion 53 and the rotation restricting stopper 56 is released, and the temperature adjusting handle 60 can be freely rotated (FIG. 15 (FIG. 6 of Patent Document 1). Corresponds to)).

Here, as shown in FIGS. 12 and 13, the safety button 52 is constantly urged by the leaf spring 55 toward the outer peripheral direction of the temperature adjusting handle 60, that is, toward the surface of the cover portion 65. Therefore, when the temperature adjusting handle 60 is rotated in the opposite direction (low temperature side) and returned to the lower temperature side than the position of the rotation restriction stopper 56, the safety button 52 automatically returns to the outer peripheral direction, that is, the figure. It returns to the state of 14.

As best shown in FIG. 13, the safety button 52 is provided so as to protrude from the cover portion 65 of the temperature adjusting handle 60. More specifically, a through hole is provided in a part of the surface of the cover portion 65, and the safety button 52 is inserted from the inside of the cover portion 65 so as to pass through the through hole.

A resin bush 54 is provided between the safety button 52 and the cover portion 65 (see FIGS. 12 and 13) so that the cross section of the cover portion 65 and the safety button 52 do not come into direct contact with each other. It has a structure. Further, the structure is such that a slight gap is secured between the safety button 52 and the bush 54 due to the sliding of the safety button 52.

Further, as shown in FIG. 13, the bush 54 is configured to cover the entire leaf spring 55. As a result, the occurrence of defects due to the sliding of the leaf spring 55 and the cover portion 65 is also suppressed.
