  • the lead wire holding grommet 40 is fitted into the left side groove portion 51c and the right side groove portion 51d of the fixed grommet 50 so as to be a part of the front side wall 54e of the fixed grommet 50. For this reason, the lead-out portion 12 of the motor body 10 and the lead-out portion 22 of the encoder 20 can be sealed with a simple structure of the lead wire holding grommet 40 and the fixed grommet 50. Can be improved.
  • the lead wire 11 of the motor body 10 and the lead wire 21 of the encoder 20 are bundled and twisted, and are covered with the heat shrinkable tube 4. Therefore, the through hole 42 of the lead wire holding grommet 40 and the lead wires 11 and 21 (lead wire 3) can be brought into close contact with each other.
  • the present invention is not limited to the above embodiments and includes all aspects included in the concept and claims of the present invention. Further, the respective configurations may be appropriately and selectively combined so as to achieve at least a part of the above-mentioned problems and effects. For example, the shape, material, arrangement, size, and the like of each component in the above-described embodiment can be appropriately changed depending on the specific usage of the present invention.
  • the embodiment of the present invention has been described by taking the case where the lead wire holding grommet 40 and the fixed grommet 50 are provided as separate bodies, but the present invention is not limited to this, and the lead wire is not limited thereto.
  • the holding grommet 40 and the fixed grommet 50 may be integrated.
  • the notch 44 of the lead wire holding grommet 40 is below the portion corresponding to the plate-shaped portion 41 of the lead wire holding grommet 40 at the center or substantially the center of the through hole 42 in the width direction (arrow cd direction).
  • the extending direction of the cut portion 44 is not limited to this, and it is sufficient that the cut portion 44 extends between the through hole 42 and the lower surface (the arrow b direction side) of the grommet 30.
  • the notch 44 is in contact with the outer surface of the motor body 10.
  • the notch 44 is not limited to being in contact with the outer surface of the motor body 10, and may extend from the outer surface of the grommet 30 not in contact with the motor body 10 to the through hole 42.
  • the cut portion 44 is not limited to the processing method.
  • the cut portion 44 may be provided by any method, and may be formed by various methods such as cut processing or integral formation by die molding.
  • the embodiment of the present invention has been described by taking the case where the fixed grommet 50 is formed in a square shape or a substantially square shape as an example, but the present invention is not limited to this and, for example, the fixed grommet 50. May be formed into various shapes such as a cylindrical shape and a prismatic shape. Further, the motor 1 has a position detector 20 as an encoder mounted on the rear side (in the direction of arrow f) of the motor body 10 as a detection device. However, the present invention is not limited to this, and may be, for example, a detection device or an electronic device having a brake mechanism, a lock mechanism, or the like, and has two or more detection devices, and all the drawer units. May be integrally covered with a grommet to be hermetically sealed.

Abstract

L'invention concerne un moteur qui est petit et peu coûteux et avec lequel il est possible d'améliorer l'aptitude au façonnage pendant l'assemblage. Le moteur (1) est pourvu d'une partie de corps de moteur (10) ayant une partie de sortie (12) pour conduire un fil de connexion (11) et un passe-fil (30) pour sceller la partie de sortie (12) de la partie de corps de moteur (10). Le passe-fil (30) a un trou traversant (42) pour maintenir le fil de connexion (11) de la partie de corps de moteur (10) et une partie découpée (44) servant de partie de séparation pour ouvrir le trou traversant (42).
