Gear motor and automatic opening and closing unit

Abstract

The invention provides a gear also difficult the emergence contacts that gear motor and automatic opening / closing means, though will to centre gripping train configuration the input / output portion configuration of the motor of tossing about mutually and detection part in a department, the wire with be used for the train. In gear motor (1), be provided with train (50) in one side (L1) of axis (L) direction for motor (40), detection parts such as potentiometer (91) of the angle position of detecting output shaft (3) are set up in one side of axis direction for the train. Be provided with from the outside of casing to motor (40) power supply and to the input / output portion (49) of the testing result of the outside output sense part of casing at the opposite side of axis direction for casing (2). When passing through between train and the casing in wire (95) that extend to input / output portion from the detection part side, make next door (832) of the 3rd supporting components (83) be present in between wire (95) and train (50).

Description

technical field [0001] The present invention relates to a gear motor having a detection member for detecting the angular position of an output shaft and an automatic opening and closing unit having the gear motor. Background technique [0002] In an automatic opening and closing unit that automatically opens and closes a toilet lid of a Western-style toilet or a lid of a washing machine, the lid body is driven by attaching a lid material to an output shaft of a gear motor. At this time, for the purpose of detecting the angular position of the output shaft, detection means such as potentiometers are provided on the output shaft and the rear-stage gear of the gear train. Here, the output shaft and the rear-stage gear of the train are provided on the opposite side of the motor with respect to the train (Patent Document 1).

Problems solved by technology

[0004] In the gear motor described in Patent Document 1, it is preferable to supply power to the motor from the outside of the casing and to output the detection result at the detection member to the outside of the casing at an input / output part provided at one place in the axial direction. The lead wire extending from the motor side or the lead wire extending from the detection part side is passed between the train and the housing. At this time, the lead wire may come into contact with the gear used for the gear train. This method is not preferable because of the situation of rotation and the damage of the coating of the wire to cause a short circuit and other unfavorable situations.
