Abstract: A feed control device includes a contact device, an output detector, a contact weld sensor, and an alarm device. The output detector is configured to detect the presence of power feeding into the side of an electrically-powered car from an external power supply. The contact weld sensor is configured to sense that the contact device is welded based on a detection result of the output detector if detecting the presence of power feeding from the external power supply to a feed line for the contact device when a state signal representing charge permission is not entered. The alarm device is configured, if the contact weld sensor senses that the contact device is welded, to indicate the occurrence of weld to the outside.

Abstract: An electricity feeding control device is provided with an air hole (31c) which is formed by penetrating a part of a peripheral wall of a body (31) constituting a part of a housing case (3). The housing case (3) is provided in its inside with an inner pressure adjusting sheet (5), formed with a breathable and waterproof member, and arranged so as to cover the air hole (31c) from the inside of the housing case (3). The air hole (31c) comprises a long recess (31c2) formed in an outer surface of the body (31), a communicating hole (31c1) consecutively formed in one end of a longi-tudinal direction of the recess (31c2) and communicated with an inner surface of the body (31), and a shielding plate (33) attached in the outer surface of the body (31) so as to cover a region other than the other end of the longitudinal direction of the recess (31c2), in a region of an opening section (31c3) of the recess (31c2).
