树脂部件、光电传感器以及树脂部件的制造方法
摘要：
本发明提供高品质且通过简单的制造工序获得的树脂部件、利用那样的树脂部件的光电传感器及那样的树脂部件的制造方法。树脂壳体具有：壳体（31），具有接合面（31c），由树脂形成；中间壳体（41），通过熔敷接合在接合面（31c），由能够透射激光的树脂形成；盖罩（21），相对于中间壳体配置在与壳体相反的一侧，立设在中间壳体上，由树脂形成。盖罩（21）具有：从中间壳体（41）立起的侧部（21a）；顶部（21b），在隔着中间壳体（41）与接合面（31c）相对的位置上与侧部（21a）相交叉。若以接合面（31c）为基准，则侧部（21a）和顶部（21b）相交叉的高度H在与接合面（31c）相对的任一位置都相同。
摘要（英）：

The present invention provides a resin part having high quality and produced by a simple manufacturing process, a photoelectric sensor using the resin part described above, and a method of manufacturing the resin part. A resin case includes a case (31) having a bonding surface (31c), and made of resin; an intermediate case (41) bonded to the bonding surface (31c) by welding, and made of resin that can transmit laser light; and a cap cover (21) arranged on the opposite side of the case (31) with respect to the intermediate case (41), standing on the intermediate case (41), and made of resin. The cap cover (21) includes a side portion (21a) standing from the intermediate case, and a top portion (21b) crossing the side portion (21a) on the position facing the bonding surface (31c) via the intermediate case (41). The height of the position (H) where the side portion (21a) and the top portion (21b) cross each other with the bonding surface (31c) being defined as a reference is the same on any position facing the bonding surface (31c).
