It is conventionally known that an electric lock device is attached to a door. For example, in the one disclosed in Patent Document 1, a bracket plate that is in contact with the inner surface of a residential door and is fixed to the residential door side, A casing that houses the electric drive means and makes one surface abut against the inner surface of the housing door is attached so that one surface of the casing is covered with the bracket plate, and transmits the power of the electric motor to the lock mechanism side. Is inserted through the through hole of the bracket plate.

Japanese Unexamined Patent Publication No. 2011-17242

By the way, as disclosed in the above-mentioned Patent Document 1, in a structure in which a bracket plate having a through hole through which the transmission shaft of the electric drive means is inserted is attached to one surface of the casing that contacts the inner surface of the house door. Condensation and rain water generated on the inner surface of the steel sheet may enter the casing through the through hole from the gap between the one surface of the casing and the bracket plate, and may adversely affect the electric drive means.

The present invention has been made in view of such circumstances, and provides an electric lock device for a residential door that can prevent condensation and rainwater from entering the casing from the inner surface of the residential door. Objective.

In order to achieve the above object, the present invention is for transmitting an electric motor and power exerted by the electric motor to the lock mechanism on the inner surface of a house door provided with a lock mechanism for switching between a locked state and an unlocked state. The one surface of the casing is fixed to the flat bracket plate fixed to the housing door side while abutting one surface of the casing housing the electric drive means having the transmission shaft. In the electric door locking device for a house door in which the casing is attached so that a part of the housing is covered with the bracket plate, and a through hole that penetrates the transmission shaft is provided in the bracket plate, It opens above the abutting bracket plate and opens on the upper surface of the casing, and on the left and right sides of the bracket plate on the side surface of the casing. Mouth to grooves, the first being formed on the one surface of the casing.

In addition to the configuration of the first feature, the present invention has a second feature that the pair of grooves are formed on the one surface of the casing so as to sandwich the bracket plate from above and below.

According to the first aspect of the present invention, the side surface of the casing is opened on the upper surface of the casing above the bracket plate that is fixed to the housing door side by contacting the inner surface of the housing door and on both the left and right sides of the bracket plate. A groove is formed on one surface of the casing, so even if condensation or rainwater that has traveled from the top of the casing to the inner surface of the door reaches between the casing and the housing door, the condensation or rainwater will remain above the bracket plate. In this way, the groove on one side of the casing will guide it to the left and right sides of the casing, and condensation and rainwater will not enter the casing through the gap between the casing and the bracket plate or through the through hole of the bracket plate. There is no adverse effect from condensation or rainwater. In addition, it is possible to expect a heat dissipation effect that releases heat generated by the electric drive means when air flows in the groove.

Further, according to the second feature of the present invention, since the pair of grooves are arranged so as to sandwich the bracket plate from above and below, it is possible to correspond to both a residential door for right opening and a residential door for left opening. Can do.
